Cleaning glassware
- Dirty glassware and plasticware goes on the carts.
- There is one outside of 32-306 and inside 32-311.
- Periodically, wheel the carts to the dishwasher in 32-322 and load the glassware into the dishwasher.
- Cylinders must be handwashed. They won't get washed properly in the dishwasher.
- Before you start a load, also check 32-316 to see if there are gel trays and combs that need to be washed.
- Add Alconox dishwashing detergent to the soap container and outside the soap container.
- Don't add too much detergent or it won't all dissolve in the wash.
- Start the dishwasher on the heavy cycle (setting 2).
- Set the cardboard sign on the dishwasher to clean.
- Once finished, unload the dishwasher onto the table next to the autoclaves.
- Add autoclave tape to each piece of glassware.
- Doing this immediately helps to identify the glassware as clean.
- Fold a side of the autoclave tape under to make it easy to remove later.
- Beakers and cylinders can be covered with foil and autoclave tape added to the foil.
- If available, load autoclavable glassware and plasticware into the clean autoclave.
- Make sure the lids are loose.
- Sterilize the glassware for 1hr at 121°C.
- Once the autoclave cycle is finished and the pressure returns to zero, open the autoclave. If the autoclave is still hot, the heat should dry the glassware.
- If the glassware and plasticware is still wet, move it to the oven (on the ground, next to the autoclave).
- Heat in the oven for 1 hr at 50°C.
- Replace the glassware to the appropriate cabinets.
Some things to remember
- Do not wash cylinders in the dishwasher. You must wash them by hand.
- Do not put clean glassware on the dirty glassware cart. Otherwise, it will just get washed again.
- Do not overload the dishwasher with detergent.
- Do not leave dirty glassware in the sink.
