EZE-Seal® Stirred Laboratory Reactors

Seal this (100 to 4,000ml) high pressure laboratory reactor with low torque

The EZE-Seal® high pressure & high temperature, laboratory chemical reactor is easily sealed using low torque. The "Double Delta" metal gasket creates a seal with low clamping force by a wedging action in V-shaped grooves. The 3,300 psi @ 850°F (227 bar @ 454°C) pressure rating is based on the stress level limits of ASME Boiler and Pressure Vessel Code Section VIII Division 1. (An ASME code stamp is optional). See the "EZE-Seal® Pressure Vessels" bulletin for pressure ratings at other temperatures.

  • The closure design can be sealed with O-rings for improved sealing ease with compatible process fluids / temperatures

  • 316SS & HASTELLOY® C-276 materials are standard; other corrosion resistant alloys are offered

  • Standard capacity range of 100 to 4,000 ml is suitable for lab use as a continuous stirred tank reactor (CSTR) & slurry

  • Access to the interior is easy since the vessel can be lowered with all the process fittings & tubing attached to the cover

  • A large diameter fitting (with valve) in the cover is used for adding powders & solids including catalysts & initiators

  • Sparging, charging, blowpipe, sampling & cooling coil process connections are ideal for most chemical reactor processes

  • The stirred reactor uses a 3,300 rpm MagneDrive® magnetic mixer that eliminates dynamic seals for trouble free mixing

  • Optional process control instrumentation measures & controls temperature, mixing speed & pressure

  • Obtain expert, process equipment advice from the manufacturer & ongoing support from the local, factory approved supplier



Ease of cleaning & elimination of foot bearings reduces the risk of cross-contamination. It offers easy access for high pressure & high temperature, chemical synthesis of corrosive, hazardous & very reactive chemicals / petrochemicals as well as solvothermal reactions. It is delivered custom configured & after full functional testing for fast & easy start-up. See ZipperClave® Reactors for pressures up to 2,200 psi (151 bar). See Bolted Closure Reactors for pressures up to 5,000 psi (379 bar).
