COLORIMETER

$180.00

This cleverly designed, self-contained sensor produces excellent results and will appeal to the Biologist and Chemist. Any reaction that causes a change in opacity, or gives a colour change can be used to study rates of reaction.

Ideal for teaching the characteristics of enzyme kinetics and chemical rates of reaction.

The sensor’s thick, black casing ensures that colorimetric results are not affected by ambient light.

It is supplied with four 35 mm slides (red, orange, blue and green) that produce light of a specific and consistent wavelength, and a pack of cuvettes with lids.

Activities:

  • Enzyme concentration versus rates of protein, starch and fat breakdown
  • Enzyme inhibition
  • Lambert Beers law
  • Acidic breakdown of sodium thiosulphate
  • Quantitative analysis of sugar

The Colorimeter is designed to measure the amount of light penetrating a solution. Transmittance (%T) is the amount of light being received, referenced to light sent. Absorbance (Abs) is the amount of light absorbed by the solution.

A white LED is used as the source of illumination, thus it does not heat the solution being studied, giving better control when rate reactions are being studied.

Power for the Colorimeter comes from the EasySense unit.

Four coloured filters are provided to allow for the selection of wavelength of light during an investigation (Red 630 nm, Green 560 nm, Blue 470 nm and Orange 600 nm).

The cuvettes supplied are made of optical polystyrene, 10 mm x 10 mm with a 4.1 cm3 capacity.

Works with the following Dataloggers:

VHub4 and VHub8
