Digesters with
increases of temperature
Instruments for wet digestions of liquid or solid samples
projected according to G.L.P. Good Laboratory Practice.
The range from room temperature to 450°C is able to satisfy
all the requirements for standard and Kjeldahl digestions.
The analyzed sample is up to 15 ml for liquid or 5 g for solids.
The digestion time varies according to the treated material
and to the used methods.
 The Velp digesters allow a work in reproducible conditions,
with a full safety, saving chemicals, work and space in comparison
to the traditional methods. It is possible to remove the evolved
fumes using specific accessories without the use of a fume
hood.
The structure of the digesters is manufactured from stainless
steel and is protected by a special resin and paints giving
a high resistance to chemicals and mechanical corrosion.
The heating block holding the test tubes allows an optimal
distribution of heat al all the selected temperatures. Its
location within the instrument avoids that in case of liquid
spillages these will reach and damage Internal parts.
The temperature of the heating block is controlled by dedicated
electronics with a microprocessor. The temperature probe does
not require a calibration which is performed by the electronics
at each turning up. This allow a very good precision and repeatability
of tests. It is possible to upgrade the software of new version
by using a personal computer for the innovative electronics
with microprocessor.
It is possible to select up to 20 work programs. For
each work program it is possible to select up to four temperatures
with the corresponding durations according to GLP (Good
Laboratory Practice) it is possible to send the data related
to a performed test to a printer or to a personal computer
for their storage.
The DK6/48 grants an efficient sucking of the fumes without
working under fume hood, using the specific accessories.
