New Products

Cambridge Glassblowing Ltd are pleased to announce the following new products:

Wipe Film Evaporators are ideal for concentrating, distilling, or reacting products that possess one or more problematic characteristics, such as heat sensitivity, high viscosity, and tendency to foul heating surfaces. In wiped film and short path distillation, the separation, purification, or concentration of heat sensitive materials occurs under vacuum, but at a residence time that is greatly reduced in comparison to more conventional distillation methods.

The unit consists of two parts; the heated glass evaporator and the head plate rotor assembly. Material is feed into the evaporator above the rotor and a thin film of the product is wiped onto the heated glass surface by glass filled PTFE rollers, this method keeps the heated material contact time to a minimum. The resulting vapour can then be processed using a separate condenser attached to the exit port. Heavy volatile materials can be collected via the bottom exit port.

Cambridge Glassblowing Ltd supply two sizes of wipe film evaporator units the CG6 surface area 0.6m² and the CG10 surface area 0.10m². As with other glassware produced by Cambridge Glassblowing Ltd, designs can be tailored to suit the customer’s requirements. We can supply our customers with complete systems, or components including, wiper motors, vacuum pumps, support stands, condensers and collection flasks.
