How to enquire / order

» Metal / Glass / Multiple / Interchangeable SS & Glass / Interchangeable Metal Stirred Autoclave



E.g. to order a 2 ltr. Stirred Autoclave of SS 316 with 100 bar pressure @ 250°C, with split clamp bolt sealing, removable head with FLP top mounted IIB motor, Electrical Ceramic Heater & Trolley model, code should be made A-2Ltr.-316-100-250-N-H-XB-EC-TL
Similarly for Glass it will be, G-2ltr.-316-6-150-N-H-X-EF-TL (where 316 is the MOC of other wetted parts like head & fittings)
For Interchangeable Autoclaves mention the first size only, 2nd will automatically be considered, Use IM or IG as prefix.
» Bottom Stirred Autoclave : The coding remains the same as above, except remove the head mounting style code, stirring motor code, heating style code & temperature code. i.e. B-2 ltr. - 316 - 100 - N-TL
» Non Stirred Pressure Vessel - the coding remains the same as above, except remove the stirring motor type code in between i.e. P-2Ltr-316-100-250-N-H-EC-TL
» For Pilot/Plant Scale Reactor give following code & details of the internal & external fittings required.
» Rocker/Shaker Hydrogenator - It has common single setup to accommodate all the vessel sizes of different MOC



For e.g. a Rocker Autoclave with 100ml, 500ml & 2 ltr. Glass & SS 316 vessels with Electrical heating & Table Top Mounting, will generate following code.
R-100ml-GLS-316-500ML-GLS-316-2Lit-GLS-316-TT-EC
