We recently introduced our new semi-synthetic hydrocarbon oil with superior chemical stability and performance. An anti-oxidation additive extends the useful life of the oil, which, with its low vapor pressure, makes this oil the ideal choice for a variety of applications. Another highlight in this segment is our exclusive partnership with Solvay Specialty Polymers, bringing their successful Fomblin® and Galden® fluids and greases to our stable of top quality oils.

Vacuum Pumps

KJLC makes it easy to find the right product. Navigate the online menu to shop by pump type, technology or manufacturer to access the most comprehensive range of vacuum pumps available from any single supplier. We proudly represent only the finest pump manufacturers in the world. Since some customers shop by ‘brand loyalty’ while others choose on price/performance alone, we have listed our pumps for easy access using either approach.

Traps & Filters

The Vacuum Mart Division offers a full range of traps, filters, and abatement systems required to protect the vacuum chamber from vapors produced by the pumps. These devices also protect the pumps from gases and particulates originating in the chamber, and protect people and the atmosphere from materials in both pumps and chamber. Customers can select foreline traps, system traps, mist eliminators, oil filtration units, and complete exhaust gas abatement systems, as well as a reclaim service for expensive vacuum fluids trapped in contaminated oil filters.

Pressure Measurement

KJLC offers a full line of gauges and gauge controllers, including convection, thermocouple (T/C), Pirani, diaphragm and capacitance manometers, hot and cold cathode gauges,leak detectors, and all ancillary inlet systems, replacement parts, and filaments. Most items can be purchased online, including those with a complex option list, since KJLC features ‘configurators’ to help select the exact option list and automatically build the part number and price.

Gas & Liquid Mgmt

Because modern vacuum processes require regulated gas flows, calibrated helium leaks, cooling water, liquid nitrogen, compressed air for pneumatic valve operations, and other considerations, KJLC’s Gas/Liquid Management line carries all necessary valves, flow regulators, plastic tubing, and compressed air fittings.

Thermal box sources can occasionally be used when heating the same material multiple times.Select tantalum baffle box and the appropriate baffle cover per application.

Thermal Rod Sources

These products help to produce thin films of chromium by evaporation for the electronics and optics industries. They represent several advantages over chromium chips, including good thermal efficiency, better regulation of film thickness, elimination of spalling, and a 99.9% pure chromium composition.

Crucibles & Crucible Heaters

Intermetallic crucibles, a proven reliable choice for thermal evaporation of aluminum, are available through KJLC. Due to the wetting characteristics of liquid aluminum, taller crucibles help inhibit material spillover by maintaining a cool lip around the top while also extending the life of both the crucible and crucible heater. Thin films of titanium also can be evaporated from intermetallic crucibles. Film thickness may be limited to 500Å. The crucible may need to be replaced for each subsequent run

Target Bonding

KJLC remains a leader in target bonding technology. Our in-house service allows the Materials Division to serve our customers more quickly and ensure a quality bond every time.Indium – the preferred material for bonding sputtering targets due to its superior thermal conductivity and efficiency in drawing heat away from the target – also is more malleable and forgiving than other solders. Certain applications may require an alternative optionsuch as elastomer bonding or different backing materials. Let the experts in the Materials Division help you determine what is right for your process.
