Bottom Stirred Autoclaves

Salient Features

  • For high through-put catalyst screening / testing / research / QC
  • 4 nos. or 6 nos. parallel reactors
  • 25ml to 750ml volume
  • Pressures upto 200 bar (2900 psi) & temperatures upto 200°C
  • Available in different Material of Constructions (MOC) like SS-316, SS-316L, Hastelloy B/C, Monel, Inconel, Titanium etc.
  • Bottom Magnetic Stirring
  • Very compact, economical & maintenance free
  • Automated PC controlled option to continuously monitor, control & record various parameters like temperature, pressure, motor speed, gas / liquid flow, pH, turbidity, IR etc.
  • Our Bottom Stirred Autoclaves / Reactors are used in laboratories for less viscous liquid and gas applications. We can supply volumes right from 25ml upto 2Ltrs with pressure and temperature combination of 100 bars and 180°C respectively. This gives a price competitive alternative to our overhead stirred reactors. It is compact in size with built in control panel for easy accessibility
