Chem Stores has a number of bulk solvents that may be purchased. They are dispensed in 2L volumes, in glass bottles. A deposit is charged for all bottles, and when they are returned to Chem Stores, the deposit is credited to the holder's account. Due to the high cost of replacing bottles, we ask that customers not use solvent bottles for waste. Appropriate containers can be acquired from the Environmental Safety Facility for waste. To avoid contamination of the solvents, please do not rinse the solvent bottle with any reagent. Please notify Chem Stores staff when returning bottles if you suspect anything other than the labelled solvent was in the bottle.
For bulk solvents, labs have the option to provide their own 4L amber bottles for solvent refills. In this case, solvents are dispensed in 4L increments (must order 4L per amber bottle). Bottles must be given to us with proper WHIMIS workplace labels (sample labels (PDF)) and labels identifying your lab (e.g., supervisor name and location). Bottles without either label will not receive refills!
All bottles and carts dropped off will be refilled the next day and available by the afternoon. If more than four (4) solvent bottles are needed, we ask that customers drop off a cart for refilling. For carts, please submit the solvent refill form (DOCX) prior to drop off.
Please bring a container (bottle, tote, bin, etc.,) to transport chemicals. Totes and large bins can be purchased if needed; Chem Stores does not have any available to borrow. If more than one bottle is required, please bring a cart or an additional person to help.
When ordering via the email form, please specify if you are returning 4L bottles for refill or are using our bottle deposit system. This should be clearly reflected in the quantity section of the form (e.g., CACE27, drum acetone, 2 x 4L).
