This kit comprises all that you need to make a start in this interesting practical area of conventional and biological chemistry. The Biochrom Colourwave WPA CO7500 colorimeter is a value for money instrument that has been designed for use in schools and colleges. It is compact, lightweight and ergonomically designed to withstand student use! This makes it ideal for use in busy teaching laboratories. It has a large easy to read display, and is simple to both set up and use, giving rapid results. Samples can be measured in either standard or semi micro 10mm pathlength cuvettes, or in 16mm diameter test tubes. The choice of absorbance or percentage transmission read out allows explanation of the fundamentals of colorimetry. The integral Kinetics mode permits the study of rates of reaction and results can be output to PC, chart recorder or printer. The eight filters are held in an integral filter wheel preventing any accidental loss or damage, however they can be removed if required. With no lid needed, this robust instrument is easy to use, clean and store. There is a drain hole at the bottom of the cell compartment so that spillages do not affect the instrument. Lamp life is extended as it is only on during the measurement cycle. The kit also includes a pack of 100 cuvettes:. Made out of UV grade PMMA. Accurate throughout the UV/ Vis range (280 - 800nm). 4 Transparent sides. 4.5ml (12.55 x 12.65 x 44.5mm). 10mm Path length. Supplied in a dust proof expandable polystyrene box with a lid. And two cuvette racks (may vary from image shown): Cuvette rack made out of moulded polypropylene, it holds 20 standard 10mm optical path cuvettes. The holes in the upper tie are specially shaped so that only the corners of the cuvettes make contact with rack, eliminating the possibility of blemishing the optical surfaces of the cuvette. The rack is stackable and is autoclavable up to 120°C. Rack Dimensions: (L)117 x (W)108 x (H)111mm.
