KRÜSS M5000 Fully Automatic Melting Point Meter

Series: Melting point meters

Model: M5000

M5000 uses automatic transmission measurement for objective melting-point determination of powders from 25 to 400 °C.

Application / measured object:

Fully automatic capillary melting-point determination of powdered samples.

Application area:

Product overview

M5000 automatically detects changes in sample transmission and determines melting point, reducing observer variability. Rapid preheating and fan cooling support sequential measurements across the range.

Advantages

Melting-point detection and sample observation

  • Transmission measurement detects the melting point automatically, reducing subjective judgement; an alarm signals the melting point.
  • One capillary position for powdered samples up to 400 °C.
Capillary sample preparation for melting-point measurement.
Capillary sample preparation for melting-point measurement.

Heating programmes and rapid cooling

  • Selectable 1, 2, 3, 4 or 5 °C/min heating rates for unknown substances.
  • Rapid preheating and automatic cooling with an integrated fan reduce waiting between measurements.
  • Approximately four minutes to 200 °C and nine minutes to 300 °C.

Display, records and supplied items

  • LCD displays key measuring data in German or English; wipeable membrane keypad.
  • RS-232 outputs data to a separately purchased CBM910 printer.
  • Delivery includes a protective cover and 100 capillaries.
