5810HEATING MANTLES
Heating mantles designed to meet the highest electrical standards. The flexible mantle is suspended above a thermal insulating ‘Former’ which provides maximum heat transfer coupled with minimum risk of flask breakage. The outer housing is constructed from aluminium metal, finished with heat and marr resistance epoxy polyester paint, which is conjunct the insulation. To ensure a safe, lower outer case temperature. All mantles have indicator lights temperature control regulator and a cord.

5814MELTING POINT APPARATUS
MELTING POINT APPARATUSThis apparatus is very useful in the determination of the melting point of any substance in small quantity upto 300°C. It consists of an aluminium block which accepts three capillary tubes and a mercury thermometer. The block is heated by two elements clamped to the sides. The built in lamp provides uniform and shadow less illumination of sample tube, which are viewed through the magnifying lens against either a dark or bright ground selected by rotating a knob to the rear of the apparatus. A built in a rotary rheostat gives accurate adjustment of the rate of increase of temperature as melting point is approached. Both the heaters are kept ‘ON’ in the ‘LOW’ as well as ‘HIGH’ position of the toggle switch, thus ensuring uniform heating from both sides of the block. A second toggle switch on the right side connects the lamp and power input to the apparatus. A sturdy metal enclosing the heating block and controls is powder coated with textured siemens grey finish.


5818MELTING POINT APPARATUS WITH COOLING SYSTEM
A single knob on the front panel incorporate the mains ON/OFF switch this gives a temperature range from ambient to 350°C with an arbitrary scale of 0 to 10. A rapid heat switch allows higher temperature to be obtained in a shorter time. A lamp provides uniform shadow less illumination of the sample tubes, which are viewed through a 25mm diameter magnifying lens. A light or dark background cab be selected with a control at the rear of the apparatus.


5822MELTING POINT APPARATUS PRECISION DIGITAL
MELTING POINT APPARATUS PRECISION DIGITALThis is a compact instrument designed for accurate determinations of melting points of solid samples. The unit consists of a builtin magnetic stirrer, an electronic controller for adjusting the rate of heating of silicon oil bath, an ON/OFF switch, a pilot lamp, magnifier, a glare free illuminated background, a HIGH/LOW range selector switch and a digital temperature indicator with sensor. The outer body is made of 304 grade stainless steel. The silicon oil bath consists of a plain cylindrical container of corning glass having capacity about 200ml. It is having a Teflon cover with five holes. Three for holding the capillaries, one for the boiling point tube and one for the temperature sensor. Besides, it is fitted with a special type of oil immersion heater.
The rate of heating of the bath can be precisely adjusted by the controller on the panel. The tips of the capillaries filled with sample powders can be kept suspended in the oil bath through the cover. The tips can be clearly observed through the magnifier on the illuminated background of the bath. A highly sensitive sensor is fitted to the equipment so that the melting points can be correctly determined by varying the temperature of the bath. A STOP button is fitted on the front which is to be pressed when the desired change is observed in the sample under test. The temperature reached at that stage is then held on the digital display heating can be start again by re-push the stop button. The operator can concentrate on the visual observation of the sample without looking to the thermometer, the readings obtained are very accurate. The range of the apparatus is from about 2°C above room temperature upto 300°C, with readability 1°C. The apparatus is supplied with 175ml silicon oil for use upto 300°C and a box of capillaries. It can also be used for determination of boiling point, flow points and molecular weight Rast’s method with special tubes, not supplied with the instrument.
