The  Cole-Parmer MP-250D-PR operates from a low voltage source for safety and convenience. The viewing arm is adjustable in length and angle to ensure that the samples are easily seen and also to prevent operator fatigue. When not in use the viewing head folds flat for easy storage. A x8 magnifier with wide viewing angle and high intensity illumination allows good visibility of the three sample capillaries. The oven used to heat the samples is microprocessor controlled to provide the fastest warm up and the most accurate temperature control. Capillary tubes up to 2mm diameter can be used and the tube guide is removable for cleaning and insertion of the cold finger.

Model MP-250D-PR

Provides similar features to the MP-250D-P but allows in addition, two discreet melt temperatures to be recorded for each capillary tube. This feature enables, for example, the clear recording of a “start of melt” and “full meniscus” temperature for each of the three samples under test. A tube select key toggles between the sample tubes and LED indicators on a head up display behind the viewing  lens show which tube is selected.  The batch memory allows storage of up to 500 sets of results and conditions.

Maximum temperature 400°C. With 13 position membrane keypad, adjustable 0.2 to 10°C/min ramp rate facility, temperature and batch memory, USB flash drive output, printer socket and RS232 interface. Includes facility to record 2 melt temperatures for each capillary tube. Supplied with power supply for 230V 50/60Hz single phase input and storage capacity for 100 capillary tubes.
