Description
Parr Instruments® Micro Benchtop Stirred Pressure Reaction Vessel, 25 mL 4590-25ML-T-SS-M-115-VS.12-600-4848 [Representative Image]
Features:
- 25 mL stainless steel vessel (T316)
- Flat PTFE gasket for 350 °C
- Magnetically coupled T316 stainless steel guide (180 nm) for stirrer
- 115 V power supply
- Variable speed motor 1/8 hp
- Pressure guage and rupture disc: 600 psi
- Process controller managed by PID (Proportional-Integral-Derivate) algorithm for programming and controlling ramps, isotherms and thermal cycles
- Use of Series 4590 Reactors also helps minimize quantities of waste products which may require special disposal procedures
- Now available in high pressure (5000 psi) or high pressure/high temperature (500 °C) versions
- These micro reactors have been designed to provide as many features of larger vessels as possible in limited space available
- All standard head fittings are provided, with optional cooling available with aluminum block heaters with cooling capability, welded jackets or Cold Fingers
- These systems are offered in both fixed head and moveable head vessel styles with choices of self sealing O-ring for temperatures up to 225 °C or with FFKM O-ring for temperatures to 275 °C or with flat PTFE gasket for temperatures to 350 °C, or with Flexible Graphite gasket for temperatures to 500 °C with HP/HT option (for fixed head versions only)
- Split ring closure is standard
- All three volumes use the same ceramic fiber heater
- Can be easily converted from one size to another by simply substituting larger or smaller cylinder and corresponding internal fittings
- Support system can also be readily adapted to accept any of the vessels from 4560 Mini Reactor Series
- Opportunity to modify these small reactors is restricted because of limited head space available
