1 ANALOGUE MELTING POINT APPARATUS With a manually adjustable heating rate, the SMP11 will rapidly heat samples up to 20°C per minute to the melt temperature and up to the maximum temperature of 250°C. Accurate readings to within 1°C of the melt temperature can be achieved by using a slower heating rate of between 1 and 10°C per minute. Up to three samples can be viewed and tested at any one time. Samples are illuminated by a bright white LED and viewed via a magnifying lens. The magnifying lens can be detached for cleaning. Supplied with a safe, spirit filled mercury free thermometer and Pack of 100 Melting Point Tubes (open both ends). Easy to follow instructions are printed directly on to the apparatus. Dimensions: 370 x 140 x 110mm (W x D x H) Mains 230V. Cat No. Description Price Per MEL-050-100 Analogue Melting Point Apparatus - SMP11 674.00 ea. MEL-050-150 Spare thermometer, Spirit Filled, 0-250°C 45.23 ea. 2 MELTING POINT APPARATUS - DIGITAL -NEW! An economic, easy to use yet advanced digital melting point apparatus, utilising a precise thermistor control system to provide an excellent measurement range, with a display of 0.1°C resolution. The apparatus is designed to simultaneously measure two samples. The internal LED light source, together with clear magnified lens and tilting rear feet, enables users to have a broader and clearer view of the samples being tested. The measurement range is from ambient (room tem- perature) to 300°C. The device has two heating speeds (fast & slow) to make measurement much quicker and more convenient, and these adjustable ramp rates and hold function make the device ideal for education use. • Temperature range: Ambient to 300 °C • Temperature accuracy: ± 1.0 °C at 20 °C, ± 2.5 °C at 300 °C • Display: Four-digit LED • Display resolution: 0.1 °C • Readout hold: Yes • Number of samples: 2 • Fast Stage Ramp rate: 20 °C /min (fixed) • Slow Ramp rates: Adjustable between 1 to 10 °C • Dimensions: 160 x 220 x 170 mm (w x d x h) • Net weight: 1.8 kg • Electrical supply: 230V, 50Hz, 75W Cat No. Description Price Per MEL-400-100 Digital Melting Point Apparatus 595.84 ea. 3 MELTING POINT TUBES Soda glass capillary tubes for use with melting point apparatus, for melting point determinations.
