A five-element instrument from Sherwood Scientific brings unrivalled precision, ergonomic design and ease of maintenance to the market for low-cost industrial flame photometers.

As a world-leader in flame photometry Sherwood Scientific is renowned for developing instruments with the highest levels of stability and reliability. The Model 360 is a single channel unit built around the very same mixing chamber, burner stem and burner head found in Sherwood's acclaimed Model 410. It also incorporates the advanced automatic flame optimisation technology from the dual channel 420 series. As a result the 360 is fundamentally more stable, less noisy and with lower limits of detection than would be expected in such a cost-effective instrument.

Ease of operation is ensured by the ergonomic design, which uniquely places all the controls, the pressure gauge, air regulator and sample introduction on the front of the instrument. The large unobstructed sample work area features an innovative spill containment tray which is easy to remove and clean. LEDs on the front panel indicate the filter selected - sodium, potassium, lithium, calcium or barium - and the flame status. A useful display ‘hold' button ensures that readings are not lost before they have been recorded and the peak picker function presents unambiguous results.

According to Jon Copsey, Sherwood Scientific's Marketing Manager, ‘The 360 responds to the current demand for five filters as standard in a low-cost instrument. However, incorporating Sherwood's world-renowned stable flame technology eliminates the need for constant recalibration during use, while providing the levels of precision, reliability and ease of use typically associated with a much higher cost unit. Applications include the analysis of sodium in food, drinking water, waste water and cement manufacture, and the 360 is also an ideal choice for the education sector.' 

The instrument has a conveniently small footprint of 20 x 30 cm and provides exceptional ease of maintenance. The mixing chamber, burner head and burner stem come apart for cleaning without tools and the five-element filter stick is simple to remove. Electronics and pneumatics are housed in separate ‘pods' which are easily detached from the main instrument chassis. This greatly reduces shipping costs in the event that a return-to-base repair or replacement becomes necessary. Similarly, the 360 is shipped with the chimney removed as the smaller volume reduces air freight costs significantly.

Model 360 flame photometers provide enhanced value by including a selection of standard solutions and spare parts within the price.
