The user-friendly Hand-Tight OPTI-SOLV® In-Line Filter System is well suited for a number of applications, such as high temperature, high-pressure environments where quick changes are imperative. The unique swivel design allows frits to be changed without removing the connecting tubing. Just plumb it once and leave it. The frictional forces generated at the piston/seal interface inevitably lead to particulate shedding. Placement of a filtering element between the pump and injector/ auto sampler removes these particulates, preventing problems with downstream components and costly downtime.
