Electromatles EME and EMEA
Controlled Heating for Soxlet Extraction - Electrothermal

Choice of 3 or 6 recesses for 100, 250, 500 or 1000ml flasks - and stirring!

The Electromatle EME extraction apparatus has been designed to maximise safety. Each recess is provided with a new electronic controller that enables easy regulation of each heater. These controllers use solid state electronics to remove the sparking normally associated with mechanical switching.

For additional operator protection a safety earth (ground) screen encloses the heaters and in the event of a spillage the heater cartridge can readily be replaced.

External surfaces are PTFE-coated and resistant to most chemical solutions. The robust construction permits continuous operation of the units as required by routine extraction tests.

The EMEA incorporates in addition to the features above a stirring module that allows the solution to be stirred and heated at the same time.

Replaceable Heater Cartridge
The flexible heating element is located within a thermal insulating 'former' to provide maximum heat transfer coupled with minimum risk of flask breakage. Supplied as a complete 'cartridge' for quick and simple replacement.

Safety Earth (Ground) Screen
This pre-formed, stainless steel screen is fitted above the heating element and earthed (grounded) directly to the supply cable. It provides additional operator operator protection should spillage or flask breakage occur.

Each recess has a built-in solid state energy regulator for heating control.

Indicator Lights
Indicator lights show when power, heating and stirring are on.

A single stirring module controls the stirring on the three recesses in the EMEA3. Two separate stirrer modules - and two controllers - are used on the EMEA6. Stirring speeds are continuously variable from 50 to 10000rpm. A PTFE coated stirring bar is provided for each recess.
