Stage 1: Process Design. This stage requires a validation strategy. A cleaning validation master plan should already be in place and include items such as cycle development, selection of cleaning agents, analytical and sampling methods, calculating acceptance criteria, handling and storage procedures for cleaned components, and cleaning equipment validation.

You can degrease ground glass joints by wiping them with a lint-free towel soaked with ether or acetone. Wear gloves and avoid breathing the fumes. The deionized water rinse should form a smooth sheet when poured through clean glassware. If this sheeting action is not seen, more aggressive cleaning methods may be needed.

after these initial steps you can go on to more aggressive cleaning protocols. Scrape away any thick solid material from the glass if possible. Wipe away any grease from the glass joints with a solvent like acetone which can be used to help remove the grease. Put the glassware in a warm cleaning solution of detergent and water.
Rinse bottles by shaking or swirling, then drain the rinsate downstream or along streambank. Rinse once for chemistry samples or three times for toxicity samples. Use certified pre-cleaned bottles for toxicity samples. Where possible, collect samples near stream center by submerging sampling bottles less than 0.3 m below water surface. Fill
The following protocol was used to assess pH shift in autosampler glass vials from different sources. In this case 1st hydrolytic class tubes have been used with examples of 33, 51 and 70 expansion type raw glass tubes. • 1 mL 18MΩ HPLC water (Thermo Scientific™ Smart2Pure™ system (P/N 50129845)) was added to
clear glass vials are Type 1, 33-expansion glass. Type 1, 51-Expansion Glass More alkaline than 33-expansion glass and is adequate for many laboratory uses. It has an expansion coefficient of 51x10–7 ˚C and is composed primarily of silicon and oxygen, with trace amounts of boron. All Waters amber glassware is Type 1, 51-expansion glass.
Lot numbers are printed directly on the barrel of gold standard syringes, with a corresponding Certificate of Conformance ensuring certified performance to all specifications. The gold protective cap on the fused needle of the gold standard syringes prevents the glass syringe barrel from chipping as it is pressed against the inlet.
