Aspirator jars must be emptied before the pumps get flooded. Put some hycolin into the jars before reconnecting. It is your responsibility to empty full autoclave bags. Tied bags should be placed in the containers outside established cell culture for the porters to take away. Never endanger the support staff by disposing of waste inappropriately.
Users are to supply their own sterile tips and pasteur pipettes.
Make sure the waterbath is switched off. Centrifuges are a potential source of contamination, in case of spills, clean thoroughly with an appropriate disinfectant. Only items used regularly for culture should be stored within the cell culture facilities. The hycolin solution in the pipette stacks must be changed every Monday morning. The old solution must be poured down the sink through a sieve and the tips and glass in the sieve must then be disposed of in the sharps bin.
