| 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 Good Laboratory Practise (GLP) it is
possible to send the data related to a performed test to a printer
or to a personal computer for their storage.
Important
In digestions evolving fumes, acid gases
and corrosive (eg. Kjeldahl) we suggest the use of Velp systems for
sucking and neutralizing them:
