This apparatus is very useful in the determination of the melting point of any substance in small quantity upto 3000C. It consists of a block of alluminium with built-in electric heating elements prepapred from kanthal heating wire. The block is bored axially with the diameter increasing the steps. Cover glass slip or this clear mica sheets are used in microscopic tests ons the steps to form enclosure in the block which is illuminated by arrangement fixed in its cabinet. Radial holes admit a thermoment fixed in its cabinet. Radial holes admit a themoment and glass capillary into the enclosure. The specimen is kept either in the capillary or directly on the glass bottom the viewing glass. The apparatus is supplied with thermometer and capillaries. It is suitable for 230 volts AC mains. (Powder coated)

The instrument is designed for accurate determination of melting points automatically and these melting points are displayed on front digital panel. It is generally used to estimate the melting points of organic substances and is suitable for quality control and research laboratories of chemical, pharmaceutical, petrochemical, food, plastic and various other industries.
The unit consists of a built-in miniature furnace, a digital temperature indicator with necessary controls and an air circulating arrangement. The furnace is precisely constructed to form a uniform heating media in which there is an arrangement to hold the capillary containing the sample. No external heating medial like silicon oil is required.
The change in transparency of the sample of the melting point is accurately sensed by a sensitive electronic circuit and the temperature of the melting point is displayed directly on the digital readout. Being fully automatic instrument human errors during the observation of the melting points are totally eliminated
The unit is very simple to operate with minimum controls. The temperature starts increasing on pressing the 'Start' switch on the panel and is indicated by a digital display. The rate of rise in temperature can be precisely contolled by a knob on the front panel. on reaching the temperature at which the sampel melts the heating gets automatically cutoff and the air circulating arrangement starts to lower down the temperature of the system. The temperature indicating the melting point of the sampel remains displayed on the panel till the 'Clear' switch is operated
The range of the instrument is from ambient to 2750C, readability is 1.00C. The unit works on 230 volts/50 Hz A.C mains supply

This is a compact instrument designed for accurate determinations of melting points of solid samples. The unit consists of a built-in 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 PT-100 sensor
 The silicon oil bath consists of a plain cylindrical container of corning glass having capacity about 200 ml. 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 immersin heater. The rate of heating of the bath can be precisely adjusted by the controller on the panel.
The tips of the capillaries fitted 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 PT-100 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.
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 ambient up to 2500C, with readability 10C. The apparatus is supplied with 175 ml. Silicon oil for use up to 2500C and a box of capillaries. It can also be used for determination of boiling points, flow points and molecular weight by rast's method with special tubes, not supplied with the instrument.

This unit has a large capacity of washing device. Especially recommended for serological, bacteriological clinical laboratories. It operates on a siphonic principle to send a continuous flow of water over and through the pipettes. At a most normal pressure the water is completely changed in cycles of about on minute. Even at reduced pressure this washer operates efficiently. It consists of a stainless steel washing cylinder 22" height x 6" in diameter mounted on a base 10" diameter and a removable pipette holder which is of 51/2" diameter. The holder is completely made of stainless steel with a heavy mesh bottom. The cylinder has a 1/2" inlet with a removable nose nipple fsor attaching to permanent drain, if desired. This unit will accomodate pipettes upto 375 mm in length
