Capillary tubes, 1.3 to 1.5-mm dia., 150/pk.

Precision accuracy of ±0.5C provides high reproducibility of results|Meet GLP requirements with optional printer|Digital display eliminates interpretation errors|This automatic melting point apparatus is ideal for determining sample purities for quality control, educational, and research and development applications. Unit measures the reflection of incident light in the crystalline state and the increase in light transmittance during the melting process. Operation is simple insert the test tube containing one to three mg of sample into the instrument, select the starting temperature and heating rate (user selectable between 0.1C and 10C per minute in steps of 0.1C), and the visual and audible signals will indicate when the melting point is acheived. The operator interface provides graphic display aids making set up and programming simple. The large LCD displays temperature readings to 0.1C.
