View resource →Product overview
M3000 uses illuminated 10× observation for operator determination, accepts three capillaries and shortens cycles through rapid preheating and fan cooling.
Advantages
Melting-point detection and sample observation
- Semi-automatic measurement with a 10× optical system for observing the illuminated sample and judging melting.
- Three capillary positions for up to three powder samples in one cycle, up to 360 °C.
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 eight 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.
