Installation - Labtech DigiBlock ED-S Series User Manual

(1) If your unit belongs to EHD series, you will see 5~10°C temperature pulse when the
temperature is lower than 150°C, so please carefully setup and adjust the temperature.
(2) The working temperature of polypropylene tube cannot exceed 130°C.
(3) The working temperature of PTFE tube cannot exceed 210°C.
(4) The working temperature of 18 positions heating rack with Teflon coating cannot exceed
210°C.
(5) Please carefully control temperature when using acid HClO4. The temperature should not
exceed 130°C if sample includes quite big organic components. It is appropriate to increase the
temperature above 180°C when the sample decomposition is basically finished.
(6) The digestion reaction will be very strong if the sample includes quite big organic
components. We recommend not to cover the tube.
(7) Glass vessels are not easy to uncap after heating. Let the tube cup cool down to ambient
temperature.
(8) For applications where an EHD unit has to work constantly over 12 hours, it is
recommended to set temperature not higher than 380°C.
