Health Sciences Laboratory Services:
Sterilization Services

You can deliver materials between 8:00am & 5:00pm to T-276.

HS Laboratory Services provides sterilization of biohazardous materials, reagents and lab supplies, and cell culture work.

If you would rather not take care of collecting your biohazardous wastes yourself, you can use the UW contract vendor for collection, treatment, and disposal of your waste.

Biohazardous Waste

HS Laboratory Services (HSLS) has one large steam sterilizer dedicated to the sterilization of biohazardous waste with a 60 minute cycle at 121° C. Last load is run at 3:30 pm. For all biohazardous waste, load your materials into plastic trays on the processing cart in T-276, filling up the lower shelves of the processing cart first. Each filled plastic tray is considered one load. We can process 9 loads of biohazardous waste at a time. Remember to fill out the Sign-In Sheet.

Standard Operating Procedures for Biohazardous Waste

SOP must be followed before bringing your waste for processing.

Reagents and Laboratory Supplies

HSLS has two autoclaves dedicated to the steam sterilization of reagents and laboratory supplies, such as pipette tips, caps, mixed glassware, and instruments. Please drop off supplies in T-276, loading your supplies onto a small autoclave cart. Special exposure times and temperatures can be requested. Once autoclaved these can be picked up from T-286.

Cell Culture Work

For those laboratories doing cell culture work, HSLS has an oven available to do high-heat dry sterilization. Please drop off materials in T-276 to be processed for 3 hours at 195 C. Once autoclaved these can be picked up from T-286.
