JL White, LLC represents manufacturers of products machined from ultra-hard materials, including sapphire and ceramic. Whether you are looking for sapphire or ceramic pistons, windows, or other specialty parts, JL White is your contact for high quality sapphire and ceramic products. Our partners produce "build-to-print" parts with precise tolerances and excellent quality. They also manufacture parts using corrosion-resistant metal materials, like stainless steel, Hastelloy, Inconel and other materials, and can provide complete turnkey assemblies.

Sapphire and ceramic components are used in Analytical Instrumentation and Biotech applications (such as pistons, check valve components, bearings, mechanical parts, nozzles and assemblies), as well as in Medical and Dental equipment (as laser tips, lenses, and blades). Sapphire windows and lenses are required components of many optoelectronic applications such as sensors, detectors, and blue LEDs.

Check valves for high and low pressure pumps can come as complete assemblies. Check valves can operate to pressures up to 25, 000 psi and check valve cartridge assembly components can be made out of a variety of materials such as PEEK, stainless steel, sapphire, ruby, titanium, and Kel-F materials.

The valve and the actuator (solenoid) of these valves are sectioned by a diaphragm so the fluid does not come into contact with the metal parts of the solenoid. The wetted materials are PTFE, PEEK, or PPS, etc so as to be compatible with a wide range of fluids.

These are a type of valve that directly pinches tubing made of a soft material such as silicone in order to open and close it. The only wetted material is the tubing, therefore cleanliness of the flow path can be maintained and cross-contamination avoided through changing tubing after use.
