Sherwood Scientific Ltd products

By forcing enough air through a bed of particles, the particle bed may assume a fluid-like state (resembling a boiling liquid). Heating the incoming air and managing air flow rate through the sample, the Model 501 Fluid Bed Dryer provides thorough mixing and maximum contact of solid with moving air. The result; a process producing more even and much quicker drying than conventional methods.

We have two specially designed Air Compressors available for use with Sherwood Scientifics Flame Photometers; the Model 851 and the Model 855. The Model 855 Air Compressor has a water cooled trap for operation in humid atmospheres. Both compressors provide a dedicated, clean, dry air supply which is vital to achieve stable flame conditions and constant sample delivery; essential for ensuring good precision of results. The correct part number has to be specified when ordering an Air Compressor to ensure compatibility with local electrical operating voltages.

We supply primary fuel gas regulators to fit gas cylinders if required which provide a controlled pressure of gas to the Flame Photometer (preferably between 1 to 2 Bar). The gas supply from the primary regulator is supplied to the secondary regulator fitted as standard to all Sherwood Flame Photometers. The secondary regulator is factory set to supply the required internal pressure for operation of the instrument. To use Natural gas with any Model 410 Flame Photometer the Natural gas regulator kit has to be purchased and fitted to the instrument. To operate a Model 360 Flame Photometer with Natural gas you must order the appropriate Model 360 (360 00 109). Natural gas cannot be used with our Dual Channel Model 420 or Model 425 Flame Photometers.
