Rotadest - Rotary Film Evaporator

Rotadest Product Description

The DDPS Rotary Film Evaporator, Rotadest®, is a self contained, thin film rotating evaporator designed for solvents containing heat sensitive materials. 

Rotadest Applications

The evaporators are particularly suited for applications with stringent requirements for purity, visibility, and corrosion resistance. The Rotadest can be found in chemical, pharmaceutical and biotech industries and is used for the evaporation of suspensions, crystallization processes, and the drying of powders and granules. The units are designed for continuous or batch production.

Rotadest Features

The Rotadest features:

• Rotating Flask - Spherical vessel constructed of QVF corrosion-resistant borosilicate glass provides uniform heat transfer over a large surface area to the thin film, avoiding localized heating. 
• Heating Bath – heated by steam or electricity
• Drive – provides variable speed of flask rotation, sealed by a mechanical seal
• Cabinet – Accommodates all controls and utility piping

Rotadest Specifications

• Volumes from 20 to 100 liters
• Operates under atmospheric pressure or under vacuum for low temperature boiling

Options

• Custom designed glass layout to meet specific customer requirements
• Available with US electrical standards (UL components) as well as explosion proof design
• Full automation with dedicated chiller and vacuum system can be supplied upon request

Distillation Overheads

Distillation Overhead Product Description

The distillation overhead assembly comprises components from QVF's high quality World Product Range which is approved as meeting the Pressure Equipment Directive and the equipment safety regulations and which carries the CE mark.

Distillation Overheads Features

To ensure that the equipment drains completely the horizontal piping carrying the product is  installed at an angle of 5°. The inclined condenser has a rinsing neck and the receiver vessel can be emptied and rinsed out during the process by means of valve V3. The integral sampling valve V9 is used to take samples from the current distillate flow, even when operating under vacuum.

Distillation Overheads Advantages

With its safety flat buttress end, the distillation overhead assembly provides a GMP-compliant coupling.
