HPLC Pump piston

The  single piston reciprocating pump was the first of its type to be used  with high efficiency LC columns (columns packed with small particles)  and is still very popular today. It is simple in design and relatively  inexpensive.

Pistons  are, by design, a consumable part of the HPLC pump and should be  replaced on a regular preventative maintenance schedule. To maintain  peak performance and avoid unplanned downtime, sapphire pistons require  inspection every six months with yearly or as-needed replacement.  Optimize sapphire pistons offer optimal concentricity and resistance to  wear. Each sapphire rod is specifically cut in relation to the grain of  the crystal lattice, yielding maximal resistance to breakage and  superior wear characteristics. Attachment of the rod to the piston  ferrule is performed through a proprietary process ensuring  concentricity. This is an important, often overlooked procedure  parameter that has a direct effect on seal lifetime.

 JH OPTEK can provide series of Piston rods by customer request.
