##### Products & Services
Vacuum Furnaces
Vacuum furnaces are heat-treating furnaces that use a low atmospheric pressure instead of a protective gas atmosphere. This helps to alleviate surface reactions.
Vacuum Flanges and Fittings
Vacuum flanges and fittings connect runs of pipe and tubing in vacuum or process gas system to other tubing sections, pipe, hose, valves, pumps, chambers or other vacuum components.
DC-DC Converter Chips
DC-DC converter chips provide a regulated DC voltage output from a different, unregulated input voltage.&nbsp;
Biosensors and Microarrays
Biosensors, microarrays, biochips and lab-on-chip (LOC) products are microscale devices for biological, biochemical and chemical arrays. They consist of microfluidic channels and a biodetector or microsensor arrays.
Vacuum Pumps and Vacuum Generators
Vacuum pumps and vacuum generators provide sub-atmospheric pressure for a variety of industrial and scientific applications where a vacuum is required.
