Sherwood Scientific

Sherwood Scientific’s history goes back over 50 years to the founding of one of our predecessor companies, Evans Electroselenium Ltd. This company was founded in the late 1930’s by Arthur Evans and was based on the use of selenium photocell applications. The Flame Photometer and CHROMA Filter Photometer series are examples of this use. Sherwood Scientific products, now manufactured entirely in Cambridge, have also been associated with the Corning and CIBA Corning brands for a number of years. Johnson Matthey is another company in the Sherwood story. Johnson Matthey is heavily involved in the precious metals sector and two of Sherwood’s products, the Fluid Bed Dryer and the Magnetic Susceptibility Balances, were developed under their auspices. Since the acquisition of these product lines, Sherwood Scientific has developed several new versions of these products. The Model 420 is a Dual Channel Flame Photometer with Internal Standard and is available for Clinical and Industrial samples. We have also developed the Model 420Cs Flame Photometer, which comes with a Cesium reference channel as an alternative to the traditional Lithium reference channel. The Model 360 is designed for ease of maintenance while allowing analysis of one element at a time. The competitively priced Model 360 comes standard with five filters for Sodium, Potassium, Lithium, Calcium and Barium. The AUTO MSB uses the same measuring principle as the classic Evans design but is 200 times more sensitive. Sherwood added Microprocessor control of air flow, inlet air temperature and drying time to the Tornado dryer purchased from Johnson Matthey and Sherwood’s latest model, the Model 501 Fluid Bed Dryer, features membrane-sealed controls to prevent particle ingress and also reduces operating noise.
