Rotary Evaporation

Rotary evaporators are commonly used in chemistry related environments for the efficient and gentle removal of solvents from samples by evaporation under vacuum.

The evaporator consists of a heating bath with a rotating flask, in which the liquid is distributed as a thin film over the hot flask wall surfaces so it can evaporate easily. The evaporation rate is regulated by the heating bath temperature, the size of flask, the pressure of distillation, the coolant temperature and the speed of evaporation flask rotation.

Scitek offers rotary evaporation solutions from Heidolph Instruments and Genser Scientific in Germany.

Heidolph, the global technology leader in benchtop rotary evaporation offers a complete range of intelligent solutions for every application.

Intelligent evaporation stands for an overheat protection design that prevents water baths running dry, provides a detachable panel for superior ease of use from outside closed fume hoods and offers a proven vacuum seal and vapor tube system guaranteed for years of operation!

"Intelligent Distillation“ proves the difference in separation of samples, in evaporation of solvents and that quality is no coincidence.

The rotary evaporators of our Hei-VAP series create new milestones within vacuum evaporation - a well-designed concept, unmatched tightness and uncompromising high quality.

The new seal system, speed-regulated vacuum pumps as well as the new generation of high-performance condensers ensure the highest solvent recovery, increase the lifetime of a rotary evaporator and vacuum pump and reduces residue in the ambient atmosphere. At the same time, you save up to 90 % of energy costs.

In short: Whatever you expect a rotary evaporator to be; the Hei-VAP series will fulfil these needs.

A variety of additional options makes the Heidolph rotary evaporator the best solution for your individual requirements. You reach up to 40 % higher evaporation rates with our new XL condensers and achieve purest results through our innovative seal system, which enables a stable evaporation process and therefore overcomes any pharmaceutical or chemical challenge.

Convince yourself from the quality, performance and reliability of our rotary evaporators, which we exclusively develop and manufacture in Germany only.

Pilot Rotary Evaporators

The Heidolph large scale evaporators of the Hei-VAP Industrial series are perfectly designed for a great deal of different distilling processes, from standard evaporation without vacuum control up to complex distillation processes with vacuum control.

Aspects such as safety, convenience and cost savings have been considerably taken into account during the development of the large scale evaporators. This is reflected in various unique product advantages.

A temperature sensor powers off the bath in case of any uncontrolled heat-up event. The unique integrated evaporating flask support system allows for “one person operation” to remove the flask in just moments.

The automatic water bath refill system along with an additional control panel for filling and electronics allow for use over an extended period of time.
Distill your solvents safely by choosing Heidolph evaporators!

Optional automatic module allow for continuous operation of your solvent distillation process overnight and weekend.

With the Hei-VAP Industrial series you can be sure you are always on the safe side when doing automatic distillation.

Safety features guarantee a smooth distillation process, no matter what solvent you evaporate!

Distilling through automated vacuum distillation allows you to spend a significantly less amount of time on solvent evaporation tasks.

Large Scale Rotary Evaporators

Genser Scientific make high performance rotary evaporation systems with many unique features. The main design difference to all other brands is the floating evaporation bath (patented). This allows long seal lifetimes which are guaranteed for 20,000 operation hours.

Genser glassware has extremely good leak rates allowing evaporations to be performed at lowest temperatures saving energy and protecting your samples. Process yields and product purities can be further improved with the patented StaconSeal option which allows Genser rotary evaporators to achieve pressures as low as 0.01 mbar. Solutions include batch systems and fully automated production systems with up to 100l flask volume, optionally also in ATEX compliant explosion-proof design.
