- Automated and compliant Twisselmann extraction (according to ISO, etc.)
- High speed heating due to ceramic plates and individual heating zones
Features
When is it recommended to work with a recirculating chiller?
When you use a solvent like petroleum ether, a recirculating chiller should be implemented if the tap water is warmer than 15 °C. The temperature difference between the boiling point of the solvent and the cooling water temperature should be 20 - 25 °C in order to achieve a good condensation of the solvent in the condenser and to keep a good solvent recovery.
Can I re-use solvent from the tank?
Yes, all material is resistant, solvent is drained directly from the condenser.
Where do you fill the solvent?
It is an advantage to fill it by the condensers (first cycle is quicker).
Is it possible to install the unit outside of a fume hood?
Yes, only when working with D-Ether (volatility) or chloroform (toxicity), working in the fume hood is necessary.
What are the reasons to adjust the heating plate / user panel?
Boiling behavior is depending on sea level, ambient temperature and different solvent compositions (petroleum ether 40-60).
