Learning Nuances of Biosafety Cabinets for Multiple Uses

In laboratories and specific educational setups, dealing with hazardous microorganism and pathogens becomes necessary. So, adopting safety measures and devices to contain contamination becomesmandatory. This is where Biosafety Cabinets come into the picture. The units are used extensively in such setups to minimize risk of infection. They are available in various types nowadays.

In several clinical and educational setups, students, professors and scientists need to deal with potentially hazardous microorganisms. These include various types of bacteria, viruses and pathogens. It becomes necessary to deal with these hazards for teaching, demonstration, scientific research etc. To ensure the microorganisms do not get spread though air or other means, specific devices have to be used. That is why doctors, researchers and staffs in similar setups make use of Biosafety Cabinets. They came into vogue in the 1950s.

The ideal way to keep bio hazards contained
Biohazards need to be contained properly, whether it is in laboratory of a college or a clinical research institute. The usage of Biosafety Cabinets has become popular in these setups over the years. When apt precautions are taken and safety measures are adopted, these cabinets play a pivotal role in keeping biohazard contained. Generally, these cabinets are equipped with HEPA filters which are also fitted in Fume hoods. These cabinets are also used to keep contents sterilized.

The available options
There are broadly 3 kinds of Biosafety Cabinets and each offers a specific level of protection against biological hazards. The main purpose of using these units is safeguarding laboratory workers as well as the environment from hazardous biological organisms. The air within these cabinets is made to go through a HEPA filter when exiting and thus microorganisms are removed. However, these devices are not the same as laminar flow clean benches. Fume hoods cannot offer the environmental protection offered by a top notch cabinet.
The CDC has segregated these cabinets into 3 main types.
Class I cabinets give environmental and personnel protection but they should not be used for product protection. These devices are mostly linked to the building’s exhaust system.
In Class II cabinets, both the environment and contents can be safeguarded against pathogens. There are 4 sub segments- A1, B1, A2 and B2. Each type is made to comply with NSF global standards. In these cabinets, a top mounted fan draws sterile air atop the products. The air is then made to pass through the work surface. Then it passes through top mounted HEPA filters.
Class III cabinets are used largely in laboratories dealing with highly contagious bio hazards. The enclosure is mostly gas-tight and materials are entered by a double-door autoclave or dunk tank.
Buying the right device
Buying the right type of Fume hoods and cabinets to contain microorganism may not be an easy task. You have to think of aspects like work needs, ergonomics and available space at your setup. Modern cabinets also have noise reduction mechanisms deployed.

There are quite a few companies that manufacture such products and sell them online. If you want a reliable solution, try the products from MoonMed see website at: www.moonmed.com.

Immaculate Medical Equipment Sterilization with Plasma Sterilizer

Medical equipment and instruments are sterilized thoroughly to avoid all kinds of infections. Plasma sterilization is one of the latest and best techniques that are applied for the process. A plasma sterilizer is required for it and the medical equipment is put in the device for complete sterilization. Medical equipment unsuitable for low temperature sterilization cannot be sterilized via this system.
Infections are not uncommon in the medical industry. In fact instruments and equipment which have not been sterilized and disinfected in a proper manner lead to grave infections, even causing death of patients. To combat such issues successfully, different kinds of sterilization techniques are being implemented. Plasma sterilization is one of the most effective and highly used technique for sterilizing medical equipment and instruments with low temperature. And for this, a plasma sterilizer is needed with the help of which this sterilization process can be carried out. Hospitals, nursing homes as well as outpatient departments (OPD) now have sterilization machines installed so that risks of infections can be minimized.

Plasma Sterilizer Machines

Plasma technology behind sterilization
It is important to understand the technology that makes this kind of sterilization so very effective. Plasma is a gas-like substance, which contains electrons and positive ions. Basically for sterilization process, hydrogen peroxide gas plasma is used. Hydrogen peroxide is extremely reactive in nature and turns into a gaseous state when it is vaporized. To this gaseous state, an electric field is applied. The gas ionizes and electrons and positive ions are generated. This is the gas plasma. A free radical is also formed during this stage. The setup of plasma sterilization is ready. When infected and used medical instruments are placed in the chamber, the process of purification and disinfection begins immediately. Inside the plasma sterilizer, the entire process is carried out and sterilization takes place in the best manner and the cycle is quick compared to other low temperature sterilization methods.

Sterilization of different sensitive devices
The implementation of plasma technology in sterilization is greatly useful for instruments and equipment that are heat sensitive and moisture sensitive. Some examples of such devices include cameras, scopes, light cords etc. and other kinds of sensitive medical equipment. There is a specific temperature range in which plasma sterilization takes place in the best manner – the temperature remains between 104°F - 131°F.or 50-60°C.Aeration is just not required in this process and it has proved to be secure and safe. Once the sensitive instruments come out of the sterilizer, they are absolutely safe for use without risks of any kinds of infections taking place from them.

Investing in high quality sterilization device
Since sterilization has a very important role in the medical industry, it is important to choose the right kind of sterilizer for the same. Investing in a plasma sterilizer is a great idea as it provides high quality sterilization without any kinds of complaints. There are many companies that manufacture such sterilizers and Moonmed deserves a special mention(see the MoonMed website at: www.moonmed.com ). Before purchasing the device, check the warranty offered by the company so that you get coverage in case something goes wrong with the device.

Washer disinfectors and laboratory autoclaves are the most commonly used machines for carrying out such work and more knowledge about them, is a must.

Sterilization of medical equipment is one of the most important aspects in medical science. Washer disinfectors are one of the most needed and wonderful inventions in the world of life sciences. These are the preferred methods used to clean medical equipment and devices. It’s a requirement to achieve the best practice compliance. Rather, it is the efficient aid for cleaning and thermal disinfection of the medical instruments and equipment. Laboratory autoclaves are one of the most effective and efficient tools used in the fields like microbiology, medicine, tattoo and body piercing, veterinary medicine, podiatry, mycology, funeral homes, dentistry and prosthetics fabrication.There are also giant pressure chambers used to carry out sterilizing processes in large Hospitals, Labs, and Pharmaceutical and Dental practices/hospitals.

Medical Washer disinfectors

Importance of sterilization
Sterilization is the process which removes, kills and deactivates all forms of biological agents and lives which pose a danger, threat and harm to mankind. Surgical instruments and medication that already enter an aseptic part of a body is covered with blood, solid and fluid debris, tissue debris, bits of bones and other fluids. Hence they must be washed and sterilized. Washer disinfectors and Laboratory Autoclaves are just the ideal ways of doing this.

Parts of a washer disinfector
The solution to efficient aid in the process of cleaning and sterilizing medical equipment and accessories is one of the most sought answers for the growth, proper care and the well being of mankind.

The various parts of this equipment include the Flush, which removes the otherwise difficult gross contamination such as blood, tissues, bone fragments, solid debris and other fluids. The Wash removes any remaining soil by the use of mechanical and chemical processes. Rinsing helps remove the detergent used during the cleaning process having multiple sub-stages of its own to ensure a clean, unmarked and sterilized product after its use. Moonmed offers high quality, updated technology and variety of washer disinfectors.

Important things to know about autoclaves

Laboratory autoclaves can be thought of as a giant pressure cooker working under larger amounts of pressure to blast and kill all of the germs and infections on the medical equipment long enough to sterilize them. A large steel vessel in which steam or a form of gas is circulated to sterilize instruments, perform scientific experiments and carry out industrial processes. Some autoclaves have cylindrical chambers for better durability of high pressure.

Sterilization Methods And Its Impact On Medical Devices

Plasma Sterilizers

There are many information available on the internet about the sterilization methods and its equipment as well, but only here you will get to know about the impact of sterilization on electronics equipment.

In this article, you will get to know about the popular plasma sterilizer methods and their suitability with electronics.

A  Big thanks to the technologies, semiconductor that are widely found in equipment that includes medical devices. A wide range for medical applications is the requirement of today’s world  to maintain the product sterile that is free from the harmful contaminants like Fungi, viruses, bacteria and spore forms as well.

Physical Methods
There are numerous methods of plasma sterilizer , the most effective methods that combine humidity, heat and pressure in a single device is known as a Plasma Autoclave.

Autoclave Steam Sterilization
In ancient time, the heat sterilization of medical tools  is used. Under the same, the availability of moisture usually speeds up the heat penetration. Basically, the Plasma Autoclave is founded in 1879 which is a combination of heat, moisture along with an elevated pressure.

How It Works
Generally, the Plasma Autoclave sterilizer is a container that looks a lot like a pressure cooker.  It is completely filled with the stuff  that needs to be sterilized and get sealed.  The high-temperature steam is forced  under a really high pressure that displacing air in it. Whereas,destroy microorganisms with the help of irreversible  denaturation and coagulation of structural proteins and enzymes.  The time and temperature to reach the same totally depend on upon the pressure  and the form of microorganisms to be inactivated. When the required time passed, it would release steam and plasma sterilizer objects are taken out. This entire process can take around 15 to 60 minutes. It is found that there are several manufacturers that are selling the plasma sterilizer or autoclave sterilizer, but among the all, Moonmed technologies have come out as the best producer. It provides the plasma sterIlizer of high quality at an affordable price.

Issues basically Plasma sterilizer is for the stuff that can take the burden of humidity, high temperature, high pressure and much more. Basic examples are surgical equipment.Those which are semiconductor devices can handle up to 125-degree Celsius.

However, by exposing embedded batteries at a  high temperature notably reduces their lifetime.  A few gadgets that use floating-gate, inclusive of EEPROMs, can be sensitive to excessive temperatures. In any other case, one has to every now and then refresh  the reminiscence data to repair the overall charge at the floating gates. This works for laser-trimmed EEPROMs. Since the form of trim is usually no longer specified in product information sheets, it may be essential to contact the vendor for information.

There are bodily, chemical, and radiation methods to sterilize items for clinical packages. Every sterilization technique has its unique characteristics, which may additionally or won't be well matched with semiconductor devices. When choosing a particular approach, one need to do not forget the potential side effects, particularly whilst electronics are worried.

Efficacy Of Autoclave And Its Usage In Clinical Setups


Medical Autoclaves are specialized devices used in clinical setups for steam sterilization of medical apparatus. These devices may vary in size but the operating principle is the same as the pressure cookers.

In clinical setups like hospitals, clinics and diagnostic centers, doctors and nurses have to use a wide range of equipment's and specialized devices. They need such equipment's to carry out myriads of tests, perform treatments and operations etc. At any cost, maintaining hygiene and eliminating germs is a prime requirement in such setups. Keeping surgical and clinical apparatus and stuffs away from contamination is absolutely necessary. That is why doctors and medical staffs resort to precise sterilization methods and devices. One such example is Medical autoclave.

Usage of Autoclaves
The major usage of autoclaves is in clinical setups and it is used for sterilization. They are also used for neutralizing bio hazard materials before disposing them. Sometimes, equipment's used for tattooing are made germ free using these devices. Dental autoclaves are used to sterilize plenty of equipment's used by dentists.

Nuances of autoclaves
Autoclave was invented way back in 1879 by a French Microbiologist named Charles Chamber land. He was a contemporary of Pasteurization's inventor Louis Pasteur. The working mechanism of a Medical autoclave is not actually different from that of a pressure cooker. The autoclave generates supersaturated pressurized steam which is used to sterilize devices. A vent is kept on top of the device to let excess steam find a way out. The majority of autoclaves have a cylindrical shape since it helps the steam develop in a uniform way in chamber. The temperature and pressure gauges are also used.

The Medical autoclave is used to sterilize equipment's with heated steam. The heated steam and pressure eliminates nearly all kinds of microorganisms. It is way more effective than using regular method of boiling water in an open pot. When water is heated inside an autoclave the steam and pressure leads to rise in boiling temperature by almost twenty percent. This ensures the germs are killed effectively. You may find a number of Dental autoclave units in market that are computer controlled. This ensures the devices can be used to achieve accurate temperature and pressure levels as per needs.

Types of autoclaves
As a matter of fact, autoclaves come in various builds and sizes. You will find entry level small Dental autoclave devices that look quite like microwaves. They have cart like mountings beneath. This ensures smooth portability which can be a necessity in medical setups. Large sized autoclaves can be like a dishwasher in dimension. In such large sized autoclaves, sterilizing oodles of medical equipment is not a problem. It saves time and makes things easy for carrying out medical procedures.

Earlier, autoclaves were mostly manual in nature but in present generation products much human intervention is not necessary. They are mostly one touch automated devices. These devices also take less time for sterilization. In recent years, the autoclaves are not used as widely as they were in some setups. Disposable syringes and needles are preferred by such clinics and hospital managements. However, sterilization is something medical professionals cannot do without and so the importance of autoclaves will be there.
