The carbon residue test serves as an approximation of the tendency of the test material to form carbonaceous deposits. The test material is subjected to evaporation and pyrolysis under certain conditions and the residue is weighed and the mass percentage calculated.

Dropping point determinations are used for identification and quality control purposes, and can be an indication of the highest temperature of utility for some applications. The sample is heated at a prescribed rate in a precision machined cup whose sides slope toward an opening at its center. The temperature at which a liquid drop first falls from the cup is the dropping point of the sample.

Cloud point and pour point are indicators of the lowest temperature of utility for petroleum products. The sample is periodically examined while it is being cooled in the cloud and pour point apparatus.

Calibrated Glass Capillary Kinematic Viscometers Koehler offers a full selection of glass capillary viscometers for measuring kinematic viscosity of liquid petroleum products in accordance with ASTM D445 and related standard test methods.

The DT Series of analytical and high precision balances from LabPRO delivers the accuracy and performance required in a host of laboratory, industrial and educational applications.

The high precision micropipette series are essential to those who relies on accuracy, especially users in the fields of molecular biology, microbiology, immunology, cell culture, analytical chemistry, biochemistry, and genetics.

LabPRO products are specially designed to offer high performance with Swiss accuracy yet with economical value. The new LabPRO high precision micropipette is the only mechanical pipette that offers both lock/unlock mechanism and tip ejection system in one.

The LabVantage Enterprise platform is designed to scale from small single-site deployments all the way up to a global enterprise. Complex organizations tackling a large volume of data and a wide variety of work, often across multiple labs in multiple geographies and languages, can rely on the LabVantage Enterprise solution hosted from a single data center. There is no need for costly Citrix farms or complex distributed systems.

LabVantage also goes beyond a traditional LIMS to incorporate functionality found in multiple lab systems – such as ELN and LES.
