Our UHPLC fittings are manufactured from a proprietary PEEK blend (PK) which allow them to be used at higher temperatures (up to 200 °C) and higher pressures. The VHP PK One-Piece fittings are available for 10-32 coned, 6-32 coned, or M4 coned ports, and Two-Piece fittings are available to connect either 1/16 inches or 1/32 inches outer diameter tubing into 10-32 coned ports in multiple styles. VHP MicroFerrules are made from a proprietary high performance PEEK polymer blend, a material which is unique in its ability to enable the use of capillary tubing in UHPLC environments. The new high pressure MicroFerrules are available for use with 1/32 inches or 360 μm outer diameter tubing, and they are incorporated into several of our VHP products for capillary tubing.

Our 1/32 inches outer diameter PEEK Tubing Sleeves is designed to be used with any fitting made for 1/32 inches outer diameter tubing when smaller tubing must be connected. It is 1.6 inches in length. Select the appropriate sleeve from the product listing for your capillary tubing OD size. The 1/32 inches outer diameter PEEK Tubing Sleeves have a maximum recommended temperature of 125 ºC and have a pressure rating of 5,000 psi (345 bar).

All-glass assemblies are ideal for biodiesel testing, aggressive solvents, and applications where you need to minimize the materials that contact sample or filtrate. Filter holder mounts on filtration flask using a ground glass joint; order standard 47-mm filter paper separately below.

The Koehler Benchtop EDXRF Elemental Analyzer can be used to determine the amount of sulfur in petroleum and petroleum products that are single-phase. This product may be used to determine the amount of lead in gasoline as well.

The Copper Strip Tarnish Test assesses the relative degree of corrosivity of petroleum products, including aviation fuels, automotive gasoline, natural gasoline, solvents, kerosene, diesel fuel, distillate fuel oil, lubricating oil and other products. A polished copper strip is immersed in 30mL of sample at elevated temperature. After the test period, the strip is examined for evidence of corrosion and a classification number from 1-4 is assigned based on a comparison with the ASTM Copper Strip Corrosion Standards. For aviation fuels and natural gasoline the sample tube is placed inside a stainless steel pressure vessel during testing.
