| Digesters with increases of temperature
Instruments for wet digestions of liquid or solid samples
projected according to G.L.P. Good Laboratory
Practise.
The range from room temperature to 450¡ãC is able to
satisfy all the requirements for standard and Kjeldahl
digestions.
The analysed 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 Practise) 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.
