Digestion & Evaporation Systems

DigiPROBE is a PFA coated, temperature sensor which provides DigiPREP Accessories
direct control and monitoring of the actual sample temperature DigiPROBE
during a digestion.
Features
During digestion or evaporation, sample temperature and block Probe and wiring is Teflon® coated for acid compatibility
temperature are offset. Since standard temperature control is Connects to the all blocks (except DigiPREP MINI)
through the block temperature sensor, graphite block users must Can be calibrated on Keypad and Touch Screen Controllers
calibrate the offset to obtain a suitable control temperature to arrive
at a specific sample temperature. DigiPROBE provides direct
sample temperature feedback to the controller which will then adjust
the temperature of DigiPREP block on a continuous basis to
arrive at the requisite sample temperature.

DigiPROBE for 15 ml DigiTUBE 1 010-515-115 DigiPROBEs are supplied with acid resistant
1 010-505-115 DigiPROBE holders to support and position the
DigiPROBE for 50 ml DigiTUBE 1 010-501-115 DigiPROBE in the tube. DigiPROBEs are
serialized for traceability.
DigiPROBE for 100 ml DigiTUBE 1 010-500-032

DigiPROBE Tube, is a Pyrex sheath placed
over the tip of the DigiPROBE. Used
during sample digestion as protection against
cross contamination from multiple sample
rack batches. Acts as a barrier between
high concentrated acidified samples and
the DigiPROBE; extends the life of the
