How do you decontaminate a cell culture hood?
Wipe down all surfaces in the hood with soapy water and then 70% ethanol starting from the back and working your way forwards. Again, products that contain bleach are not ideal here as you do not want to damage the hood. Don’t forget the sash and the outside of the hood.
How do you clean a tissue culture room?
Maintaining the Tissue Culture Room
- Thoroughly clean water baths regularly and replace with fresh, clean water.
- Leave hood equipment in its place.
- Observe cell cultures microscopically daily to become familiar with the morphological appearance of different cells.
How do you clean a BSC hood?
Decontaminate the BSC before and after every use to prevent cross-contamination. Use a 1:10 fresh bleach solution followed by a 70% ethanol rinse to avoid corrosion and achieve good disinfection, or contact EHS if you need a bleach alternative. You can review Disinfectant Selection for further guidance.
What is HEPA filter in tissue culture?
An essential component in any clean bench or biosafety cabinet is the high efficiency particulate air filter, commonly called a HEPA filter. The HEPA filter removes particulates (generally called aerosols) such as micro-organisms, from the air. The HEPA filter does not remove vapors or gases.
How do you minimize contamination in a tissue culture lab?
How To Prevent Cell Culture Contamination
- Wear gloves, lab-coats and use hoods.
- Use your hood correctly.
- Clean your incubator and water bath regularly.
- Spray EVERYTHING with ethanol or IMS.
- Minimize exposure of cells to non-sterile environments.
How do you remove mycoplasma from incubator?
Autoclaving the contaminated cell cultures is the best way to get rid of the infections. In the case of valuable cells contaminated by mycoplasmas, autoclave cannot be helpful and an elimination method should be used without harming the eukaryotic cells.
How do you clean up cell culture?
Wipe out the cabinet used with 2.5% sodium hypochlorite….
- Discard all cell culture flasks.
- Discard all aliquots of penicillin /streptomycin, glutamine and fetal bovine serum and any open bottles of water for irrigation.
- Decontaminate the Class I / II cabinet by formaldehyde fumigation if possible.
What are the steps you should take to decontaminate the BSC after you finish working?
When you have finished working and with the BSC blower still running, decontaminate all containers and equipment. Wipe down the work surface, the sides and back of the BSC, and the inside of the glass with 70% Ethanol. Do not spray Ethanol inside a BSC. 5.
How cleaning and decontamination is done inside of the cabinet?
The cabinet must be completely cleared of any equipment, pipettes, waste, liquids and tubing. Decontaminate the surfaces of the BSC with an appropriate disinfectant, such as a 10% bleach solution followed by 70% ethanol solution.
How do you sterilize cell cultures?
For routine cleaning, wipe the work surface with 70% ethanol before and during work, especially after any spillage. You may use ultraviolet light to sterilize the air and exposed work surfaces in the cell culture hood between uses.
What is HEPA filter in microbiology?
It is an acronym for “high efficiency particulate air [filter]” (as officially defined by the U.S. Dept. of Energy). This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm).
How would you prevent contamination in a microbiology lab?
We always use pipette tips that have filters in them to avoid cross-contamination of samples. We wear gloves and use sterile forceps to collect and transport samples. Samples are frozen during transportation and once [they are] in the lab.”
