DK Digestion Units
VELP Digesters with temperature ramps
- Continuous innovation and dedication to taking care of the details
- New support system and suction caps
The digester is a widely used instrument in laboratories performing analysis for different applications,
such as digestions in the Kjeldahl process for protein determination and analysis in the environmental
field.
VELP Scientifica offers a broad range of digesters (DK 6, DK 20, DK 6/48, DK 20/26, DK 42/26).
A user-friendly program Menu allows to select up to 20 work programs while 4 temperature ramps
are available for the simultaneous digestion of 6, 20, or 42 samples in test tubes of different
dimensions (i.e., Ø 42 mm, 48 mm and 26 mm).
DK Digester Line is provided with a wide range of options (temperature selections, programmable
permanence time, “continuous” working mode availability) and with a visualization display which
allows to set the desired values and to monitor the digestion progress.
All VELP digesters can be integrated with accessories to facilitate use.
Features and Benefits
VELP DK series digesters can be integrated with accessories to save time, while ensuring safety for the
operator and work environment.
Accessories available for all DK digesters:
New Support System for the test tube holder and suction cap, facilitates sample cooling, provides
careful treatment, and maximizes space on the laboratory's countertop
Glassware handle with heat shields guarantees heating uniformity
Suction cap allows efficient fume removal during digestion; it is used with the type JP Water Jet Pump
and the type SMS Velp Scrubber
Among the main characteristics:
Friendly use – With just 4 keys, you can set different operations
High accuracy – Temperature precision is ±0.5%, with a heating speed of 20 to 420°C n 30 minutes
RS232 interface - for PC data transfer and storage according to GLP
Safety – Electronic microprocessor checks and automatically calibrates the heating block's temperature
Customizable – the operator can choose among 6 different languages
VELP DK series digesters are superior solutions for the laboratory needs and are designed and
manufactured according to International Standards.

UDK127 Distillation Unit
The New Basic Solution for Kjeldahl Analysis
- Integrated display and new software facilities
- Slim shape in a new plastic housing
- Highest performances based on the Innovative Titanium Condenser
UDK 127 Distillation Unit is a new release from VELP Scientifica and represents a solution
which further extends VELP’s offer in the distillation units range.
The new UDK 127 is provided with a housing completely covered in plastic material so
assuring improved resistance to attacks from chemical agents and an extended life time.
The Velp patented steam generator, the technopolymer splash head and the innovative
titanium condenser (patent pending) guarantee the highest performances and productivity,
with a drastic reduction of running and maintenance costs.
This unit features an integrated display and a new software which bring an excellent usability
and new operational options.
The UDK 127 is designed for diversified and flexible use, including applications such as
determining ammoniacal nitrogen, protein nitrogen, nitric nitrogen (after reduction), phenols,
volatile fatty acids, cyanides, sulphur dioxide, alcohol content, etc. according to official
procedures.
Features and Benefits
The new unit UDK 127 represents the basic solution developed by Velp Scientifica in the Distillation units
range.
Thanks to a new software and an integrated timer, the UDK 127 allows to run automatically the distillation
time and the sodium hydroxide addition. The supply water flow is automatically stopped during pauses, thus
cutting down on its consumption.
The instrument is equipped with a system that recognizes when the sliding protection door is not closed and
when the test tube is not in the proper position, without which the dosing pump does not start operation.
An innovative system allows various sizes of test tubes to be used and 500 ml Kjeldahl flasks to be housed.
Low maintenance, time saving, extend life time and cost reduction are some of the main advantages of
Velp patented steam generator.
The innovative titanium condenser allows drastically saving of cooling water thanks to an optimized
heating exchange, while the technopolymer splash head increases chemical resistance and assures
preventive maintenance reduction.
UDK 127 works in accordance with official methods AOAC, EPA, DIN e ISO.
It comes ready to use, complete with test tube, pincer for test tube, collecting flask and inlet tube.
