Instructions for use
1. Introduction
Thank you for purchasing this piece of Stuart
equipment. To get the best performance from
the SMP30 please read these instructions
carefully before use. Before discarding the
packaging check that all parts are present and

2. Safety advice before use
If the equipment is not used in the manner
described in this manual and with
accessories other than those recommended by
Stuart, the protection provided might be
impaired.
This equipment is designed to operate under the
following conditions:
❖ For indoor use only
❖ Use in a well ventilated area
❖ Ambient temperature range +5°C to +40°C
❖ Altitude to 2000m
❖ Relative humidity not exceeding 80%
❖ Mains supply fluctuation not exceeding 10%
❖ Over-voltage category II IEC 60364-4-443
❖ Pollution degree 2
Never move or carry the unit when in use or
connected to the mains electricity supply.
The unit should be carried using both hands with
fingers under each side of the frame.
The ventilation slots at the back of the sample
block should not be sealed or obstructed.
3. General description
The apparatus is designed to measure and record
the temperatures of crystalline samples held
within capillary tubes. Up to three tubes are
accommodated in an illuminated chamber within
the aluminium block. The tubes are viewed
through a magnifying lens on the front of the
unit. All controls are via the membrane keypad.
The temperature range is ambient to 400°C and
the heating rate is variable between 0.5°C per
minute and 10°C per minute. Temperatures and
instrument information are displayed on the LCD
screen. Up to seven temperatures per capillary
tube can be saved and recalled on the screen.
Three methods can be stored for repeated use
and the plateau temperature and heating rate
are fully programmable. When the melt cycle is
started the SMP30 heats up to the
pre-programmed plateau temperature at the
maximum rate before stabilising at the plateau
temperature for 120 seconds. An alarm will
sound to indicate that the SMP30 is ready to
start to heat at the pre-programmed rate. Once
the melt has occurred and the cycle stopped,
cooling is automatic to ambient temperature.
The SMP30 has English, Spanish, French, Italian
and German language options.
