EMS Poly III embedding instrument

The EMS Poly III is an instrument for the embedding of specimens by the proper combination of pressure and temperature. Central to the instrument is a specimen chamber that is temperature controlled and which can be heated up from room temperature to 70°C. The pressure in the chamber can be reduced from ambient pressure to a controlled level with an inbuilt vacuum-pump. 

The instrument chamber accepts up to 52 BEEM specimen vials. The vacuum pressure the specimens are exposed to is controlled within narrow limits and warrants solvents will evaporate in a controlled way without the risk of explosive boiling. The exhaust of the vacuum pump is connected to a chemical vapour resistant hose, which can vent into a fume hood in compliance with laboratory practices and general health and safety regulations when working with volatile substances. The instrument features preset programs which can be modified according to the user's preference. In the presets pressure and temperature settings have been coordinated and optimised for an efficient removal of solvent from the specimens eliminating the risk of boiling. Bulk removal of solvent is followed by steps for the thorough removal of trace amounts. As a practical approach the instrument can be loaded by the end of a workday and (when using acetone or propylene oxide) by the next morning the vials are ready for polymerisation after the vials have been topped off with pure resin. A lengthy and sometimes tedious manual procedure now reduced to a few simple steps.

Alternatively, to free up the instrument for a next run, polymerisation can take place in a stove. The instrument is (after cooling) immediately available for a next run.
