This is a manually operated compact instrument designed for accurate determinations of Melting/Boiling points and also molecular weights of Samples by rasts method. It is having a Silicon Oil bath and a built-in magnetic stirrer to maintain the temperature of the bath Perfectly uniform. The rate of heating can be precisely adjusted by a controller on the front panel. The range of the instrument is about 2^oC, above ambient to 300^oC

MODEL: LMP-D

This instrument is same as LMP-1. It is equipped with a magnifier to observe the tips of the melting point capillaries holding the samples to be tested. Instead of the conventional glass thermometer, it is fitted with highly sensitive PT-100 sensor and the temp. is indicated on a digital readout. A press button is provided which is to be pressed when the desired change is noticed in the sample under test. The temp. reached at that stage is then held on the readout, till the `CLEAR' button is pressed. The readings obtained are therefore quite accurate, as the operator can concentrate on the visual observation of the sample without looking on to the thermometer.

Model: LMP-DS

Sensitive Apparatus with Readability 0.1^oC.

MODEL: LMP-II

This unit has an arrangement to hold the capillary containing the sample in uniformly heating media. The temp. is indicated by a digital display readable in 1.0^oC.. At the point when the sample melts, the heating is automatically cut-off and the digital display showing the temp. Remains on the indicator till it is cleared. No Silicon Oil or other bath is required as heating media. Range: 2.0^oC, above room temperature to 300^oC. Accuracy: 0.3%.

MODEL: LMP-III

ISensitive unit with Readability 0.1^oC.

This apparatus is designed to determine the melting points of solids or boiling point of liquids, with high accuracy. It is supplied with a Silicon Oil bath with heater for heating the bath. It incorporates a microprocessor based circuitry and keys to set the desired program for heating the bath. On pressing the `START' button, the instrument automatically executes the total program. The temp. of bath rises fast in the beginning and is automatically controlled in suitable steps and adjusts the final rate of heating at 1<sup>o</sup>C/Min, towards the melting point. The sample is filled in capillaries and is suspended in the Silicon Bath through its Teflon cover. The temp. of bath is maintained uniform by a magnetic stirrer. The physical changes and melting of sample in the capillaries can be clearly observed on the background of `glare free' illuminator. A special feature of this model is that the `Range of Melting' of samples can also be determined accurately if required.

MODEL : LMP-CM

Equipped with Colour Monitor & High Resolution Camera. More Precise and accurate observations of samples, due to enlargement of image on monitor.

MODEL : LMP-BM

Instrument same as above, but provided with Black & White Monitor instead of colour monitor

Fully automatic instrument. No human errors involved. Heating rate precisely controlled by microprocessor circuit.

Details:

The instrument is designed for accurate estimation of melting point automatically and these melting points are displayed on front panel. The unit consists of built-in miniature furnace, a digital temperature indicating circuitry with necessary controls and an air circulating arrangement. The furnace is precisely constructed to form a uniform heating media, having an arrangement to hold capillary containing sample. Microprocessor based circuitry automatically controls rate of heating in steps. The change in transparency of the sample at the melting point is accurately sensed and displayed on digital readout.

The range of the instrument is 40 deg C to 300 deg C. Readability is 0,1 deg C, with accuracy : + 0.1%.

It is generally used to estimate the melting points of organic substances and is suitable for quality control and research laboratories of chemicals, pharmaceuticals, foods and various other industries.
