Short Path Evaporator
The perfect equipment for challenging evaporation application
Our GSPE-B short path evaporator guarantee excellent results when
evaporating, concentrating, distilling, or devolatilising temperature-sensitive,
high-boiling mixtures. The internal condenser minimises the pressure loss due
to its short distance from the evaporation surface. Therefore, short path
evaporators can operate under fine vacuum and with correspondingly low
boiling temperatures. Even extremely heat-sensitive products can also be
distilled without causing any thermal damage.
Why should you choose GSPE-B?
- GSPE-B is highly efficient, providing high evaporation rates, short residence times, and contamination-free operation
- PTFE wiper design that forms uniform thin film and pushes the film downwards with every rotation
- Magnetic stirrer sealing to achieve low pressure condition
- Magnetic stirrer sealing and greaseless valves and joints allow for contamination- free material processing using GSPE-B wiped film systems.
- Use of wetted part such as glass, PTFE, PEEK, FKM/FFKM which are FDA compliant and highly chemical resistant
- Adjustable feed rate that allows manipulation of film thickness which in turn modifies residence time on the heated evaporation surface
- GSPE-B short path evaporator systems is easy to clean and maintain, with easy accessibility to all parts of the systems
- Feasibility studies using GSPE-B short path evaporator systems can be performed with minimal cost. For example, large scale processes can be miniaturized, and pilot scale studies can be performed to plan scale-up
Design Highlights
The distance between heated surface of evaporator and cooled surface of the condenser is very short due to which generated vapours of low boiling components gets condensed immediately which minimise the pressure drop and ultimately keeps the purity of condensates high.
The wiper assembly consists of parts made up of thermoplastic materials only (i.e., PTFE, PEEK etc.) which are highly chemical resistant and FDA complaint; makes complete system safer to operate due to non-metallic parts inside the evaporator still.
The wiper assembly is fully modular, and blades are replaceable.
Due to its unique design, it pushes the liquid downward while forming the thin film of the liquid over heated surface of evaporator. The resident time can also be adjusted by changing the rotational speed of the wiper blades.
Our wiper blade design and its material varies according to the viscosity range of the liquid and operating temperature.
Wiper assembly can be easily removed from the evaporator still for cleaning & maintenance, without worrying glass parts getting damaged.

Upgradation for continuous configuration (GSPE-C)
Dosing/Outlet Pump:
The Outlet Pump (also known as a Gear Pump or Discharge Pump), regulates output dosage from 0- 7L/hr. This allows the operator to have control over things like residence time, flow rate, and overall time management. Attaching the Outlet Pump to your Wiped Film Evaporator or Falling Film means there is no longer a need to break deep vacuum to swap flasks. It also means you can distil as slow or as fast as needed.
The gears within the Outlet Pump create a suction and pull oil towards the outlet. Oil is transported through the external cavities of the gears’ and out the check valve. The stainless-steel gearbox maintains temperature via high density heat pad. As a result, you will have a consistent distribution of discharge material.
Note: The Outlet pump can also be used as a Dosing pump.
