C45-8550 Kjeldatherm Digestion Block Heating System, Automatic
KJELDATHERM ECO KIT
The kit consisting of a thermoplate and fan, is the perfect enhancement for
laboratories with a high sample throughput and modern energy efficiency
standards. The thermoplate is a suitable attachment for the block digestion system
C45­8550 and keeps the heat in the block up to three times longer. The plate covers
the heated block, preventing unnecessary heat losses during the cooling phase. The
additional fan significantly accelerates cooling of the samples even further. It
significantly accelerated cooling phase for samples enables quicker transfer to
Kjeldahl analysis systems (e.g. C45­8800, C45­8820 and C45­8840). The thermoplate
can be stored with the attachment on the block to save space. The fan can also be
used to reduce the block to an ideal starting temperature for the next digestion in
the case of samples with high water content.

KJELDAHL ADVANCED BASIC STEAM DISTILLATION SYSTEM
Micro-processor controlled and equipped with embedded PC and 7” TFT touch
display. The following functions are all programmable: automatic addition of NaOH,
H2O and H3BO3, distillation time, reaction time, steam power, 10–100%, and
suction of sample residue. All glass components involved in the distillation process
are back-lit for visual process control at any time.
Complies with the data management requirements of certified or accredited
laboratories (ISO 9001, SO 17025, GLP). Designed for results to fully conform (e.g.
DIN EN ISO, AOAC, EPA, ASTM, EC regulation, APHA, Ph. Eur. 2.5.33 method 7,
procedure A)
Supplied complete with tubing set.
