OEM PRODUCTS

Mott pump inlet filters are used for the protection of HPLC pump inlet check valves, and can also be used as a sinker to hold pump inlet tubing at the bottom of the solvent supply. The offering includes three types and are offered in 316L SS or titanium depending on the strength and corrosion resistance required. For other materials, consult factory.

Model 6500 – Easily adaptable to flexible tubing or compression fittings.

Model 6510 – Complete with a compression-type tube connection.

Model 6515 and 6515T – For use with ¹/₈" Teflon^® tubing, these filters are threaded for a self-tapping, positive grip connection.

Mott also offers three types of frits or porous metal discs for use in the HPLC column. This includes the UniDense, Concave and Dual-Density Chromatography Frit designs.

UniDense Chromatography Frits – Used for uniform flow across entire frit surface.

Dual-Density Chromatography Frits – Used to limit flow to the interior region of the frit, greatly reducing dead volume that can cause peak asymmetry.

Concave Chromatography Frits – Used to enhance flow uniformity, eliminating the need for a flow distribution plate.

Other product offerings Mott supplies to this industry include:

• Flow restrictors
• Standard encapsulated flow restrictors
• Filter cups (316L SS and titanium)
• Duplex frits
• Welded assemblies
