For your own safety and that of others please
read and understand the safety advice given
below before using the equipment.
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 or side of the
device should not be sealed or obstructed.
3. General Description
The device is designed to automatically measure
and record the melting temperatures of crystalline
samples held within capillary tubes. Up to three
tubes can be accommodated in an illuminated
chamber within an aluminium block. The tubes
are monitored by a digital camera; the image of
which can be viewed on the instruments display
during the melting process. The device is
designed to be independently operated using the
colour touch screen allowing all operational and
data management functions to be performed
without the need to attach an external computer
or keyboard. The unit can be split into two
modules to allow the heating module to be
located in an environment suitable for the types
of samples being tested, while the control
module can be kept in a more convenient
location.
The temperature range of the device is ambient
to 400°C and the heating rate is variable
between 0.1°C and 20°C/minute. Temperature
data and information on the instruments status is
displayed on the screen at all times. All of the
instruments functions and menus are accessed
using the colour touch screen interface which
allows fast and intuitive navigation throughout a
substance’s melting point determination (melt
determination). The instrument has sufficient
internal storage capacity for an almost unlimited
number of preset method programs and typically
between 100 and 200 result files*. When
required, result files can be transferred from the
instrument to a PC or USB flash drive for external
storage and archiving.
When a melt cycle is started the SMP40 heats up
to the pre-programmed plateau temperature at
the maximum rate before stabilising at the
plateau temperature for 60 seconds. The SMP40
will then start to heat at the pre-programmed
rate until the melt is complete or until the device
reaches a pre-determined end temperature. Once
a melt determination has been completed,
cooling is automatically engaged until the
instrument reaches 50°C.
* The number of result files that can be stored on the SMP40 is largely dependant upon the runtime and size of
the video file for each sample.
The user is able to review the result file and video, reprocessing the automatically determined results if required.
