20L Complete Dosing System


The Complete Dosing System For Wiped Film Evaporators

The Complete Dosing System by Beaker & Wrench® is a continuous feed system that connects to any Wiped Film Evaporator effortlessly. The contents of this system include: heated feed flask, 4″ tri-clamp port on feed lid, the Peristaltic Dose Pump by Beaker & Wrench®, adapter, heating element (varies depending on order), UL Listed PID, extra tubing and mounting structure.

Optimize time and end results by dialing into your feed system. The Peristaltic Dose Pump by Beaker & Wrench® gives the operator control over flow rate and freedom to load material into the flask without breaking deep vacuum. Once attuned with the flow rate, calculations become less of a guessing game and more of a formula. Distill as slow or as fast as needed!

Use the drop box to choose the size of your inlet; this is so we can provide the right adapter for your system. If you are unsure, use the “Notes” section to indicate what machine the equipment will be connected to. This is an important step!

How does it work?

Crude is loaded into a heated feed flask, which then flows through a tube routed within the Peristaltic Dosing Pump. A peristaltic pump moves fluid through a tube by the act of compression and relaxation, creating a vacuum. Oil is then pulled towards the still body, ready for distillation!


Every Operator has their own preference in how they clean their Wiped Film Evaporator. Ethanol, Isopropyl alcohol or vegetable oil are viable options when looking to clean your Wiped Film. Step-by-step instructions are included in the manual!
