Labware Washer
Published: August 20, 2018

Q. When cleaning labware, Liquinox foams too much to use as a labware washer detergent. We test for phosphate, so we need a phosphate-free detergent. We need a cleaner that will clean off any testing residual on glass and plastic without leaving any interference. Can you recommend a detergent?

A. Correct.  You may decide to pre-soak in Liquinox® Critical Cleaning Liquid Detergent but it is not meant for automated washer use, due to foaming.

Note that your labware washer will be set up to use powdered detergent in a little cup in the door or basket; or it will have a liquid dosing system for a liquid detergent.

For powdered detergent, use Tergajet® Low-Foaming Phosphate-Free Detergent. For a liquid detergent, use Solujet® Low-Foaming Phosphate-Free Liquid.

Like all laboratory grade liquid automated washer detergents, Solujet ships as a hazmat due to the potassium hydroxide ingredients.  Both Tergajet and Solujet are laboratory grade detergents intended for use in automated laboratory washers that can deliver glassware with no interfering residues.
