Note: To avoid contamination of glassware, ensure that supplied items have never been washed with detergent, washed with other glassware, or washed in facilities that might have detergent residue. Washing glassware in a common dishwashing facility can contaminate glassware with detergent residues, which may contain polyethylene glycol and other "sticky" substances. Vinyl-coated steel racks can be additional sources of contamination.

For detailed information on properly cleaning laboratory glassware, see Controlling Contamination in LC/MS Systems (715001307).
