How to enquire / order

1. Metal / Glass / Multiple / Interchangeable SS & Glass / Interchangeable Metal Stirred Autoclave

Product Coding , Selection, Ordering

E.g. to order a 2 ltrs. 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?2ltrs.?316?100?250?N?H?XB?EC?TL
For multiple autoclaves prefix should be M4 or M6 rest all same
Similarly for Glass it will be, G?2ltrs.?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.

2.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 ltrs. ? 316 ? 100 ? N?TL

3.Non Stirred Pressure Vessel ? the coding remains the same as above, except remove the stirring motor type code in between i.e. P?2ltrs?316?100?250?NH?EC?TL

4.For Pilot / Plant Scale Reactor give following code & details of the internal & external
fittings required.

5.Rocker / Shaker Hydrogenator ? It has common single setup to accommodate all the vessel sizes of different MOC
Rocker / Shaker Hydrogenator / Rocker Autoclave
For e.g. a Rocker Autoclave with 100 ml, 500 ml & 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
