Synthetic sapphire crystal has excellent mechanical properties, hardness, abrasion resistance and corrosion resistance. Therefore, it can be used as a piston / plunger rod in high-performance liquid chromatography ( HPLC ) systems. The sapphire piston / plunger rod is mounted in a stainless steel rod. The piston is part of the pump, which pushes the solvent through the system.
Creator Optics can offer all kinds of standard or customized sapphire piston / plunger rods. And can also provides assembled piston / plunger for HPLC as well. They involve multiple brands of HPLC such as Agilent, Shimadzu, Hitachi, etc.
