Approved TDS Analysis StableWeigh™ Vessels for Standard Methods for The Examination of Water and Wastewater

TDS testing
StableWeigh™ vessels, from Environmental Express, reduce hours of preparation time.

When you use StableWeigh™ vessels for TS and TDS analysis, you can rest assured you are in compliance. StableWeigh vessels, from Environmental Express, are compliant with the requirements for evaporating dishes in ASTM D5907-13, listed in 40CFR part 136 for total solids (TS) and total dissolved solids (TDS). They are also mentioned by name in SM2540 2015 in the 23rd edition of Standard Methods for the Examination of Water and Wastewater™.

What is Standard Methods

Standard Methods is the water and wastewater industry’s trusted source of accurate and proven methodology for analysis of natural water, water supplies and wastewater. The publication is a reference book covering all aspects of water and wastewater analysis techniques. Standard Methods is a joint publication of the American Public Health Association (APHA), the American Water Works Association (AWWA), and the Water Environment Federation (WEF).

StableWeigh Vessels for TDS Analysis

StableWeigh vessels reduce time spent preparing, weighing, cooling, and cleaning evaporation vessels for TS and TDS analysis. Each StableWeigh vessel is preweighed with the tare weight printed on it, so it’s ready to use right out of the box. The vessels are inert to common water and wastewater components, and heat-resistant at the temperature required by the method. The vessels do not hold as much heat energy and will cool much faster. Because StableWeigh vessels weigh much less than a traditional glass or ceramic crucible, they give results with greater precision and accuracy. Combined, these factors reduce the number of drying and weighing cycles needed to obtain a constant weight. Once the analysis is complete, the StableWeigh vessels can be disposed of which eliminates the need for washing and the possibility of carryover contamination from one sample to the next.
