4. Operation of PCMT
Recommendations during operation
•
Please check that the tubes/microwell plates are thermo resistant. Don't heat the
tubes/microwell plates over the melting point of the material they are made of (use thermo
resistant polypropylene tubes). Remember that thin-walled tubes have a higher thermo
conducting factor.
• Under high temperatures (> 85°C) tube caps can open, causing evaporation of the sample or a
potential health risk when working with infected material. To prevent such occurrences it is
recommended to use tubes with cap lock of Safe-Lock
® t y p e
.
• For efficient mixing it is recommended to fill test tubes up to 75% of the tube specified volume.
4.1 Connect the external power supply to the grounded mains and switch ON the power switch
located on the rear panel of the unit.
4.2 The display will turn on with the upper line (Set) showing time, RPM and temperature set
earlier and the lower line (Actual) showing current readings of the same parameters
(thermo block temperature °C, which automatically starts rising according to the temperature
set in the upper line). The time to reach the set temperature will depend on the initial
temperature.
Setting the PCMT
Use the readings in the upper line of the display (Set), while setting the required parameters.

Time set (TIME)
4.3 With the help
of “ ▲ ” and “ ▼ “ keys Fig. 3/1 set the required working time interval in hours and
minutes (increment - 1 min). If the key is pressed for more than 3 seconds, the increment
becomes bigger.
Speed set (RPM)
4.4
With the help of “ ▲ ” and “ ▼ “ keys Fig. 3/2 set the required speed (increment 10 RPM). If the
key is pressed for more than 3 seconds, the increment becomes bigger.
Temperature set (T, ºC)
4.5 With the help of
“ ▲ ” and “ ▼ “ keys Fig. 3/3 set the necessary temperature (increment
0.1ºC). If the button is pressed for more than 3 seconds, the increment becomes bigger.
