Washing glassware by hand in your lab is not the best or easiest way to keep your glassware clean. Instead, the right glassware washing device can help improve the efficiency of your lab, reduce your lab’s energy and water consumption, and save your lab money. This equipment cleans glassware more effectively than handwashing and limits your lab workers’ exposure to potentially harmful substances.

6 Questions to Ask When Buying a Glassware Washer:
- How much glassware does your lab use in a day and what capacity will you require?
- Is the glassware used for sensitive analyses?
- What applications are you using the glassware for and what washing conditions are required (e.g., high temperatures or forced-air drying using HEPA filters)?
- How long does it take to run a full wash cycle?
- What temperature and wash cycle options are available?
- How energy efficient is the unit and how much water does it require?
Consider the Residues
Some glassware residues are soluble in basic detergent; others require more acidic detergents to dissolve. Ensure that the residue in question is dissolved by following a basic wash with an acid rinse.

Maintaining the Washer
As a rule of thumb, a washer used four to six times a day should be fine with one preventative maintenance visit from a qualified technician per year. However, if the machine is used for eight hours straight or more, have the washer serviced every six months.
