Automatic Digestion Units
Sample preparation is a crucial part of the Kjeldahl analysis in order to obtain accurate and precise results. With the DKL series of digesters, manual operations have been drastically reduced: lowering and lifting of the samples takes place fully automatically, as well as the separation between the test tubes and the suction cup.
You just need to weigh your sample, add the reagents and catalysts and select the method.

Walk-away digestion unit to maximize productivity
DKL digesters are fully automatic and immediately ready to use, as they consist of an aluminum heating block, a lift for automatic sample handling, suction hood, test tubes, test tube rack and drip tray.
The DKL series provides the operator with the ultimate technology that allows the laboratory technician to set up the analysis choosing from a library of 54 programs (30 pre-installed + 24 customizable), press START and walk away, boosting the lab productivity.
Ease of loading and unloading make the VELP DKL a pleasure to use when carrying out Kjeldahl analysis, and there is no need to handle the sample when the tubes are hot!
Premium performance with aluminum heating block
DKL extremely fast aluminum heating block is capable of reaching 420°C in just 20 min with best-in-class temperature stability.
The choice of premium materials and the powerful microprocessor guarantee precise block temperature with an accuracy of ± 0.5°C.
Even in terms of repeatability and conductivity, aluminum offers incredibly high performance!
DKL digesters drastically reduce the time needed to reach the digestion temperature according to the Kjeldahl method.
Compact design to save space in your lab
Everybody knows that there is never enough bench space in a laboratory, this is why we have made the DKL series as compact as possible.
The narrow footprint enables you to optimize bench space according to need: fit more instruments on the same lab bench or make different use of the extra space available.
Many labs prefer to perform mineralizations under a fume hood and the compact design of the DKL ensures a minimum use of precious space.

JP - Recirculating Water Pump
Recirculating Water Pump that ensures optimum fumes aspiration during digestion.
Robust and practical design
JP is a water recirculation pump that guarantees optimal suction thanks to the two different programming modes, depending on the digestion phases and the number of samples of the digester to which the pump is connected.
The unit is made of an ABS structure, extremely resistant to chemical corrosion and the type of materials used make the instrument extremely quiet and long-lasting.
The use is facilitated by special technical devices such as the level indicator for water control, the tap for emptying the tank and two convenient handles for handling.
Combined with the special Scrubber SMS, JP provides the ideal complement for a very effective abatement of fumes developed during acid digestions.
Water consumption
JP Pump provides a considerable water saving thanks to the principle of continuous water recirculation in its tank which results in considerable savings. It is designed to offer high performance in terms of efficiency: up to 35 l/min flow rate.
The use of common water pumps is frequently prevented by the lack of adequate water pressure or high water consumption.

SMS Scrubber
Designed to neutralize corrosive and toxic fumes produced during oxidative mineralizations or similar processes.
Highly efficient fumes neutralization in 3 stages
The SMS Scrubber is designed to neutralize corrosive and toxic fumes developed during oxidative mineralization or other processes, such as digestion.
Its working process is generally composed of 3 stages:
– condensation
– neutralization with acids and bases
– absorption with activated carbon (optional – ideal for high fume levels such as with soybean analysis)
Thanks to the elevated surface of contact between gas and liquid, SMS scrubber has a wide range of applications and provides its maximum efficiency when combined with the JP Water Recirculation Pump for smoke suction.
