Rotary evaporators are distillation units that incorporate an efficient condenser with a rotary flask system. As the flask containing the solvent is rotated it continually transfers a thin layer of liquid over the entire inner surface. This gives a very large surface area for evaporation that is effected by heating from the accessory waterbath .
They are the ideal tools for many everyday laboratory applications including:
• Concentration of solutions
• Reclamation of solvents
• Vacuum drying of wet solids
• Degassing liquids
The rotating system is fitted with a special seal that allows the apparatus to be placed under vacuum. This reduces the boiling point of the solvents and removes the vapour phase making the process much more efficient.
Each unit is also provided with an easy to use vacuum release and a continuous feed system, which allows more solvent to be drawn into the rotating Florentine flask without the need to stop the operation.
There are three patterns of condenser available depending on the application and space available.
• Rotary evaporator with diagonal glass condenser for standard distillations.
• Rotary evaporator with vertical glass condenser for distillation of solvents with higher boiling points. 20% narrower than RE300 saving space.
• Rotary evaporator with cold finger glass condenser for use with ice or dry ice for volatile or low boiling solvents.
No cooling water required. Unique drain to empty the large 1 litre trap very easily.
For each condenser pattern, there is also a plastic coating option for extra safety when using the glassware under vacuum. It acts as a safety screen, contains the glassware pieces and gives the operator sufficient time to transfer any potentially dangerous chemicals to a suitable vessel without spillage.

Flocculator, SW6

Accepts six samples
Digital indication of speed and time
Two pre-set programs
Built in illumination for easy viewing of samples

For flocculation (jar) tests on water and effluent samples.
The SW6 accommodates up to six samples and is specially designed for repeatable conditions between samples and from run to run.
A digital display clearly indicates the speed of the rotational stainless steel paddles, which can be varied from 25 to 250rpm. The digital timer can be set to count down from 1 to 99 minutes. After count
down, the paddles stop and an alert sounds. The timer then counts up in minutes in order to measure settling time.
Two pre-set programs allow routine speed and time parameters to be input and then selected by simply pressing one button. Parameters are stored in the memory and can be recalled or altered at any time. The
intuitive touch sensitive keypad is totally flat for easy cleaning. Sample monitoring is assisted by diffused base illumination and black background. A simultaneous coagulant doser is available as an accessory.
