A support for a coalescer filter element comprising first and second ends, and a fluid flow bar having at least three fluid channels extending from the first end to the second end; and a filter system including a coalescer filter element arranged on the support, and a method of removing undesirable contaminants and/or fluids from gas using the filter system, are disclosed.

A buffer management system includes at least one workstation configured to support a supply of concentrated buffer solution and an inline dilution skid having a manifold. The manifold is in fluid communication with the supply of concentrated buffer solution and is adapted to be placed in fluid communication with a source of water for injection (WFI). The manifold includes a buffer inlet line in selective fluid communication with the supply of concentrated buffer solution, a WFI inlet line in selective fluid communication with the source of WFI, and a discharge line in fluid communication with both the buffer inlet line and the WFI inlet line. The inline dilution skid is configured to variably mix the supply of concentrated buffer solution and the source of WFI to obtain a range of diluted buffer solutions.

The invention provides a material comprising (i) a crown ether of formula (I), (ii) a crown ether of formula (II), and/or (iii) a crown ether of formula (III), or a salt thereof, wherein each m independently is an integer from 1 to 8, p is an integer from 1 to 1000, each “ ” designates an optionally present bond and/or structure, each X is an optionally present substituent, each * independently represents —H, ═O, or a bond to a remainder of the material, provided that at least one * is a bond to the remainder of the material, and wherein the remainder of the material is bound via a sp3-sp3 carbon-carbon bond, a method of making the material, and a method of using the material.

An inertial separator including an inlet tube with an undercut, an outlet tube with a spiral ramp, and a scavenge flow outlet, is disclosed.

A filter for filtering particulates from a fluid stream includes a filter element, a first end cap, a second end cap, and a wrap. The end caps are respectively secured to the ends of the filter element to form a fluid tight seal therebetween. At least one of the end caps defines an opening therethrough in fluid communication with the interior passage of the filter element. The wrap is in the form of a strip secured to at least the filter element. The wrap comprises a conductive layer comprising an electrically-conductive material. The wrap is wrapped around the filter element such that at least forty percent of the outer surface area is covered by the conductive layer.
