Lab Test Tubes

Minimum Detergent Concentration?

My question is related to a minimum detergent concentration.  We manually wash labware of all sizes in 0.3% Liquinox solution. We also pre-wash or pre-rinse the labware and control our parts load.  We rarely have failures. We want to change our protocol to extend the wash water use for one day instead of based on a numerical parts load.  Do you think a 0.3% Liquinox concentration is sufficient detergent capacity to go an entire day?

Automated Labware Washer Detergent

Q. Liquinox foams too much to use in the labware washer. 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.
A. Detergent choice for cleaning labware in an automated laboratory washer depends upon whether you use powered or liquid detergent. Click for details. For powdered detergent, use Tergajet phosphate-free low foaming powdered detergent, catalog number 2204 for the 4 lb box size. For a liquid detergent, use Solujet phosphate free low foaming liquid detergent, catalog number 2101 for the 1 gallon size.
