Good Laboratory Practice Series: Glassware


The measurement of trace constituents demands methods capable of maximum sensitivity. This is especially true for metals and trace organics such as pesticides, as well as for the determination of ammonia and phosphorus. In addition to sensitive methods, however, there are other areas that require special consideration. One such area is that of the cleanliness of laboratory glassware. Obviously, the very sensitive analytical systems are more sensitive to errors resulting from the improper use or choice of apparatus, as well as to contamination effects due to an improper method of cleaning the apparatus. The purpose of this course is to discuss the kinds of glassware available, the use of volumetric ware, and various cleaning requirements.

7.2 Types of Glassware
7.3 Volumetric Analyses
7.4 Federal Specifications for Volumetric Glassware
7.5 Cleaning at Glass and Porcelain
7.6 Special Cleaning Requirements
7.7 Disposable Glassware
7.8 Specialized Glassware
7.9 Fritted Ware
7.10 Special Considerations (perhaps a discussion on claims of Teflon Class A labware)
