Introduction

• This Thermo Scientific Thermal Mixer provides mixing and temperature control of samples in micro test tubes or PCR plates.
• Features of thermal mixers meet the highest expectations of users according to many parameters:
• Fast reaching of specified mixing speed and maintenance of equal amplitude of rotation throughout the thermal mixer block;
• Stability of maintaining the set temperature in a wide range throughout the block surface of thermal mixers;
• With the help of the temperature calibration function, the user can calibrate the unit to approximately ±6% of the selected temperature to compensate differences in the thermal behavior of tubes from different manufacturers;
• LCD display indicates pre-set and current values of temperature, speed, and time of operation; 4
• Quiet motor operation, compact size, prolonged service life;
• Sensor error handling and diagnostics;

Functions of heating and mixing can be performed either simultaneously or independently, which allows using the unit as three independent devices:

• Thermostat;
• Shaker;
• Thermo-shaker.

We offer five heating and cooling blocks for each model, including a block with a plastic lid for PCR plates. Within one model of the thermal mixer, the blocks are mutually interchangeable and can be easily installed.

The devices are applicable in:

• Genetic analyses – in the extraction of DNA, RNA, and further sample preparation;
• Biochemistry – for studying enzymatic reactions and processes;
• Cellular biology – extraction of metabolites from cellular material.

• Lift the block without damaging the cable and disconnect the plug (fig. 1 /1 ). Select the new thermo block and install it according to the previous paragraph.

Operation

Recommendations during operation

• Please check the tubes/microplates before using, be sure that tubes and microplates are heat-resistant.
• Do not heat the microplates over the melting point of the material they are made of.
• We recommend filling tubes and plate wells up to 75% of the rated volume for efficiency.
  • Caution! The platform surface becomes very hot during use. Please, take necessary care and use protective cotton gloves to install or remove test samples when set temperature is higher than 60°C.
  • Caution! The heating/temperature maintenance process does not stop when the timer is finished.
• Platform thermal regulation can be turned off only by setting the required temperature below 25 °C (the display will show OFF – Temp – set point). In this mode, the thermal mixer can be used in cold rooms as a mixing device without thermoregulation.
  • Caution! Do not fill microtubes or microplates directly inside the unit.
  • Note! If the rotation speed is set to zero, pressing the rpm Run/Stop key will start the timer but the platform will not move.

Starting the unit

• Connect the external power supply to a grounded power socket and set the power switch, located on the rear panel of the unit, to position I (on).
• The display will turn on with the upper line (Set) showing the time, speed, and temperature set earlier and the lower line (Actual) showing current status: STOP indication, 000 pm speed and platform temperature in °C.
• If a temperature is set, then the platform temperature automatically rises to that temperature. The time of temperature stabilization depends on the room temperature. If the heating of is turned off by setting the temperature below or 4°C, top line shows an indication OFF.

Setting the parameters

• Use the readings in the upper line of the display (Set). while setting the required parameters. Pressing the key for more than 3 s will increase the increment rate. Speed and temperature can be changed during operation.
• Using the and Time keys (fig. 3/1) set the required working time interval in hours and minutes (step 1 min).
• Using the and Speed keys (fig. 3/2) set the required speed (step 10 rpm).
• Using the and Temp keys (fig. 3/3) set the necessary temperature (step 0.1°C).

Program execution

• After the thermal stabilization of the thermal mixer, i.e. when the set and current temperature readings become the same:
• Place samples on the platform.
• Press the rpm Run/Stop key (fig. 3/4). The platform will start rotating and the timer indicator will start counting the time interval (with 1 min precision).
• After finishing the program (after the set time elapses) the platform motion will stop and the timer will show the flashing reading STOP accompanied by the repetitive sound signal until the rpm Run/Stop key is pressed.
• If the working time is not set (or is reset) and the timer indicator in the upper line shows 00:00, pressing the rpm
• The run/Stop key will start the continuous operation of the device with a countdown timer in the lower line (Actual) until the rpm Run/Stop key is pressed again.
  • Caution! At the end of the set time period, the platform movement is stopped automatically, but the heating can be stopped only manually by reducing the temperature using the Temp key (fig. 3/3 – lower key) till the OFF sign appears in the upper line (Set) of the display
  • Caution! The platform remains hot after use. Please, take necessary care and use protective cotton gloves to install or remove test samples when a set temperature is higher than 60°C.
• If required, there is the possibility to restart the timer when it is running.

Calibration

Note: Values marked in grey on figures 4 and 5 are not used in calibration and are meant for service engineers.

1. Calibration mode indicator;
2. Calibration coefficient;
3. Temperature with current coefficient

Note. Coefficient value changes are recommended after the unit has reached 30°C temperature.
Note. Calibration coefficient can be changed in range from 0.936 to 1.063 (+0.063), with increment of 0.001. This calibrating coefficient will correct temperature through all the operation range.

• Set the 1.000 value using the and Temp keys as shown in Fig. 4/1 to restore the factory settings. Press the rpm
• Run/Stop key once to save the changes and exit the calibration mode.

Calibration procedure

• To calibrate the unit, use an independent sensor with 0.5°C accuracy, which can fit in the cell of a microplate on the platform.
• Install the sensor into a cell of the microplate.
• Set the required temperature in operation mode, e.g. 40°C. After the unit reaches the set temperature (when the set and current temperature readings equal), leave the unit for 30 min for thermal stabilization.
• Let us assume that the readings of the independent sensor is 39°C, but the display’s actual temperature is 40°C. Then, it is necessary to add a 1°C correction.
• Hold the Time Run/Stop key pressed for more than 8 s to activate calibration mode (figure 4).
• Using the and Temp keys, change the calibration coefficient (fig. 5/1) so that the new temperature value (fig. 5/2) corresponds to the independent sensor temperature.
• In our example, the calibration coefficient will be 0.974.
• Press the rom Run/Stop key once to save the changes and exit the calibration.
• The display will show the calibrated temperature as shown in fig. 6/1 and the unit will continue thermal stabilization according to the previously set temperature.
