Rotary Pipette Stand

Moulded in Polypropylene, the unique Rotary Pipette Stand holds a maximum of 94 pipettes and rotates on a central vertical axis for convenient selection of any particular pipette. The lower rotating disc has four concentric troughs with tapered sides and open bottoms that cradle the pipette tips protectively and permit water drops to run off. The upper disc has a grid pattern concentric with the bottom disc and keeps the pipettes vertical. Liquids draining off the pipettes are retained on the top of the stationary base by the outer ring. Our Rotary Pipette Stand can be easily disassembled and reassembled.

Microprocessor Photo Colorimeter

Microprocessor Photo Colorimeter is a compact and easy to operate instrument for Photo Colorimeter analysis of any concentration. The output is available on a 16 x 2 line alphanumeric backlit LCD display in terms of %Transmission (%T), Absorbance (Abs.), Concentration (Conc.) and K Factor. This instrument has 100 sample storage memory and printer output facility for printing data with any dot matrix printer. The use of microcontroller has made it extremely versatile and accurate instrument. 10 mm path length matched test tubes are used for sample and blank. The use of high class standard wide range glass filters covering 400 to 700 nm give extremely good results. The filter setting is controlled by a rotating disc having 8 filters. An automatic shutter is provided to stop the light reaching the photocell, when test tube is not inserted in the tube holder. This increases the life of photocell tremendously. Facility has been provided to store the last K Factor and the standard concentration value. User can also enter any known ‘Factor’ for a test, thereby eliminating the need to re-run the standards again and again.
