This test method is a procedure for the measurement of viscosity of liquids using a digital rotary viscometer. This method can capture data points at a multitude of temperatures, rotational speeds, and rotor diameters, and is especially effective for data determination in non-Newtonian fluids
This test method measures the volatile suspended solids (VSS) content in water or wastewater samples—representing the organic portion of suspended solids, which is essential for monitoring biological treatment processes.
The USP method for Carbon Dioxide in Water quantifies the amount of dissolved CO₂ in water samples. This method ensures accurate measurement of CO₂ content in water, important for quality control in pharmaceuticals and other industries where water purity is critical.
This test method is an approved method for determining the anaerobic plate count or total viable count in food and dairy products. It is widely used in food safety, quality assurance, and environmental monitoring as a rapid, space-saving alternative to traditional agar methods, with an incubation period of 48 hours in an anaerobic environment.
This test method is an approved method for determining the aerobic plate count (APC) or total viable count in food and dairy products. It is widely used in food safety, quality assurance, and environmental monitoring as a rapid, space-saving alternative to traditional agar methods, with an incubation period of only 24 hours.
This test method quantifies the volume of solids in a sample that settle out of suspension within a specified time under quiescent conditions. It is used to assess the settleability of solids in treatment processes, such as sedimentation in wastewater systems.
This test method is a gravimetric procedure for determining Total Solids (TS) in water, wastewater, and sludge samples by measuring the residue remaining after drying.
This test method determines Total Suspended Solids (TSS) in water and wastewater samples. TSS refers to the dry weight of particles trapped by a glass fiber filter.
This test method is used to determine the temperature of a substance using a certified thermometer.
This test method is a procedure for determining Total Volatile Solids (TVS) in water, sludge, or wastewater samples. TVS refers to the portion of total solids that is lost upon ignition at 550°C, representing the organic matter content.
