Heidolph UK's Hei-Vap intelligent rotary evaporators are available in three options: Value, Advantage and Precision.
The Hei-Vap range features a novel detachable operating panel, which allows precise control of all important parameters outside the fume hood.
Advantage and Precision options feature an easy-to-read LCD display.
In addition, an upgraded heating bath features enhanced safety, heats to an unmatched 210C, accepts large flasks up to five litres and features a convenient pouring spout for spill-free emptying.
All Hei-Vap units feature an integrated flask clamp designed to aid removal of flasks from the drive, without jamming.
The patented glass vapour tube, clamping sleeve and graphite-filled PTFE seal are engineered to reduce wear and consumption of spares by up to 75 per cent.
The new entry-level Hei-Vap Value offers analogue control with an easy-to-use hand lift at an affordable budget and is ideal for all standard evaporating applications.
The mid-range Hei-Vap Advantage features an LCD digital display for control of rotation speed, heating bath and display of vapour temperature.
The Advantage model also includes an automatic process timer, which turns off the evaporator at a pre-programmed time and, on motorised lift models, removes the evaporating flask from the bath.
The Hei-Vap Precision has integrated vacuum control and is designed for the most demanding applications.
The Hei-Vap Precision has a large colour LCD graphic display with vacuum control for automated distillations.
The unit is ideal for all kinds of difficult applications and prevents foaming, excessive bubbling and bumping.
The Hei-Vap Precision's microprocessor control allows users to store programs for common applications, pre-program vacuum gradients and control process time.
It includes a USB data interface.
