Q: Which of your detergents would be recommend to wash glassware used to clean Fecal MPN test tubes in a lab washer. Does it have an Inhibitory Residue Test?
A: The borosilicate glass test tubes typically used in fecal Most Probable Number (MPN) assays need to be reliably clean each and every time.
Typical smaller scale washers have a cup-in-door type detergent compartment that is used in many labs. If so, we would certainly recommend Alcojet® Low Foaming Powdered Detergent. If a phosphate free detergent is needed, as many water and environmental labs do require, Tergajet® Low-Foaming Phosphate-Free Detergent would be the choice.
Finally, if you have a liquid dispensing washer in which a liquid concentrate detergent is needed, Solujet® Low-Foaming Phosphate-Free Liquid would be the way to go.
These above detergents will help remove fecal and other organic matter in a low-foaming, washer safe detergent format with their low foaming emulsifiers and alkaline hydrolysis removal mechanisms.
In all washer style applications, Citrajet® Low-Foam Liquid Acid Cleaner/Rinse is an excellent detergent for a washer’s rinse aid cycle.
The inhibitory residue tests are found on our website once you establish your detergent’s master lot from the COA. Linked below, respectively.
