The Cole-Parmer MP-250D-F 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-250DF-F
Meets the requirement for basic sample testing. Up/down keys are used to set ramp start temperature, then a standard ramp of 1°C per minute is used to heat the sample. If the melt temperature is not known, a 10°C per minute search ramp can be used to give coarse measurement of melt temperature. When watching the samples for the melt to occur a temperature storage button is pressed to record up to four discreet temperatures in the memory. These temperatures can be recalled later on the LCD display.
