Description
Thermoreactor laboratory “TERMION” is designed for heating samples in reaction vessels to a predetermined temperature and holding at it for a predetermined time.
The thermoreactor is made in the form of a monoblock consisting of a heated thermoblock with electronic control and a removable stand with a stand.
At the back of the monoblock there is a heated thermoblock with 29 slots for Hach type vials and a slot for installing (if necessary) a control thermometer. In the working position, the tripod is mounted on top of the thermoblock of the device, the vials are held in the tripod holes with their own covers; after the exposure is completed, the tripod is removed from the thermoblock and placed on the stand. In front of the monoblock there is a control panel (keyboard and display) of the device.
Operating procedure
Vials with prepared samples are placed in a rack. In accordance with the MVI set the necessary time and temperature of heating. The heating and holding operations occur without interruption: at the command of the operator “Start”, heating of the thermal block begins; when the set temperature is reached, a double beep sounds. Vials with prepared samples are placed on the thermoblock. The hold time countdown starts; after the set time has elapsed, a single sound signal is given, the heating is turned off and the natural cooling of the thermoblock begins.
The last temperature and exposure time values entered by the operator are stored in the device’s non-volatile memory.
Operating conditions of the thermoreactor:
Ambient temperature 10 … 35 °C
Relative air humidity at +25 °С 30 … 80%
AC supply voltage 198 … 242 V
AC frequency 49 … 51 Hz
applications
The thermoreactor can be used as an auxiliary equipment in analytical laboratories, for example, to determine COD.
