Pennwalt Laboratory Super-centrifuges
PENNWALT LABORATORY SUPER-CENTRIFUGES
Pennwalt Laboratory Super-centrifuges are available for general purpose laboratory use, complete with electric drive motor to solve innumerable research and industrial separation problems. The development driven by Pennwalt Biosciences’ vision to help drive innovation in the biotechnology and pharmaceutical sectors.
When required, units can be equipped with heating or cooling coils. The units can be operated at capacities for general purpose in the continuous flow range 100ml/min to 500 ml/min and upto a maximum of 800ml/min. The electric motor drive is limited to a maximum bowl speed of 25500 rpm, which achieves a gravitational acceleration of 16200x G. The Laboratory Super Centrifuges can be used for several purposes :
Laboratory Super Centrifuges
Removal of Suspended solids from a liquid wherein the clarified liquid is discharged continuously and insoluble solids are collected on the inner wall of the rotating bowl.
Separation of two immiscible liquids from a mixture of liquids continuously fed to the Super Centrifuge. The separated heavy phase and liquid phase liquid discharge continuously with insoluble solids if any deposited on the inner wall of rotating bowl.
The effective capacity of the machine is application specific, depending upon factors such as the nature of emulsion being processed, upon the settling characteristics of the insoluble solids and the settling characteristics of the light and heavy liquid phases.
Maximum speed: 25500 rpm
Maximum Centrifugal force: 16200 x G
Drive: Electric motor suitable for single phase 50/60 cycles A.C supply
Material of Construction: Rotating bowl, discharge covers, feed nozzle and all contact parts in stainless steel. Cooling coils in copper or stainless steel. Frame in case iron-epoxy coated or stainless steel if required.
Accessories: All necessary special tools, integral speed indicator with variable frequency drive.
Optional Extras
Heating or cooling coil fitted to the frame
Stainless Steel Frame
Self sealing rotor bottom
Additional Bowl of the same or different types that are interchangeable
How it works
The rotor is suspended from drive mechanism by a flexible spindle which is driven by an electric motor.
A loose fitting guide bushing at the bottom permits the rotor to assume a centre of rotation about its own centre of mass. The liquid is fed to the rotor through a feed nozzle at the bottom. Immiscible liquids form layers within the rotating bowl with the liquid phase of higher specific gravity forming the outer layer towards the wall of the rotor and lighter liquid of lower specific gravity forming the inner layer. The rotor inner wall collects the insoluble solids. The heavy and light liquids are discharged via separate ports through covers. The complete unit is rugged and simple to operate.
