Pharmaceutical Cleaning — Insoluble Residues
For best results removing water insoluble pharmaceutical residues in a labware washer there are several factors to pay attention to:
1) Be sure to load glassware separated from other glassware in a way that will not trap wash solution between pieces of touching glassware.
2) Be sure to load glassware tilted in a position that will drain all surfaces so as to avoid any upturned “cup” that will retain wash solution and carry it in the rinse cycle where it gets redeposited all over other glassware – a classic example of this happens when you load a graduated cylinder straight upright and the base of the cylinder holds wash solution – it is best to load graduated cylinders at a bit of an angle.
Cleaning Glassware with Acid Rinse
Q. I use a Miele glass wash machine and currently use Alcojet. I am wondering if I need to use a two step wash with an acid rinse to be sure the glass is residue free. What detergents would you recommend for either a one or two step cleaning process?
A. Alcojet detergent is free-rinsing, meaning it rinses completely away with water and without rinse aids. There are no softeners, brighteners, fragrances or other residues that are not involved with the specific action of aqueous cleaning. Having said that, we know of many applications that do still involve an acid rinse/wash.
Citrajet as an Alternative to Deconex 26 PLUS
Q. Our current cleaner is no longer available. We need a suitable replacement for Deconex 26 PLUS. This was specified by Inst. Mfgr. with no alternatives.
Food Contact Surface Cleaners
Q. What are two Alconox brand cleaners are low foaming and USDA approved for cleaning food contact surfaces?
A. Alconox, Inc. manufactures cleaners for food contact surfaces with no interfering residues.
Industrial Laser Chiller Cleaning
Q. Chillers get scale build-up that reduce their heat transfer efficiency, thereby reducing their chiller performance. In particular industrial lasers need good chiller performance.
Therefore, use a 2% Citranox or Citrajet solution to remove calcium scale build-up. Be sure a 100 micron filter of adequate flow rating is installed in the coolant path. Be sure no galvanized pipe is in the system. Learn More.
