Capability Matrix

Temperature range × form factor × typical use. Custom builds extend any axis.

Form factor	Range	Typical use
Heating jackets & tapes	up to 450 °C	UHV chamber bakeout
Bakeout tents	up to 300 °C	Synchrotron / accelerator beamlines, multi-chamber UHV systems
Heating cartridges	up to 800 °C	Sample stages, manipulators, effusion cells
Tube furnaces	up to 1000 °C	CVD, catalysis, materials synthesis
Flow / gas-line heaters	up to 600 °C	ALD / MOCVD precursor lines, carrier-gas preheat
Insulation jackets	passive	Heat retention on chambers and lines
Temperature controllers	multi-zone PID	Programmable ramp / soak with safety interlocks

Materials

• Silicone — flexible, UHV-friendly up to ~200 °C, good for chamber and component wrapping.
• Glass-fiber — workhorse insulator, sustains 450–550 °C, the default jacket material.
• Ceramic — rigid mantles and hoods, 1000 °C class, used for tube furnaces and high-temp process heating.
• Inconel-sheathed elements — cartridges and tube heaters for corrosive / high-temp environments.

Short Lead Times & Custom Builds

Catalog jackets and tapes ship from stock. Custom geometries are quoted directly — chamber drawings or a measured sketch is enough to start. No minimum order quantity.
