SpeedDigester K-425 / K-436

SpeedDigester - flexibility, speed, reproducibility Flexibility: Use of 300 or 500 ml tubes with the same instrument Speed: Time savings due to short heat-up and cool-down times Reproducibility: Reproducibility thanks to homogeneous heat distribution

Cost-optimized flexibility

Using the SpeedDigester IR digestion systems, new standards are set in speed of digestion, flexibility and reproducibility. Using these systems, a wide range of samples can be digested much faster than conventional digestion systems. The automatic SpeedDigester K-439 is also the world's first IR digestion system with temperature control, so that exact temperatures can be set.

On these two systems the heating level is adjusted using continuous controls. The optimized design of the heating chambers reliably ensures all samples are homogeneously heated, an aspect that prevents the foaming of critical samples. The acid fumes produced are removed with the aid of the optional Scrubber B-414. As a consequence the ambient air in the laboratory remains free of harmful vapors.

SpeedDigester K-425

6 x 300 ml sample tubes or
5 x 500 ml sample tubes with the same instrument

SpeedDigester K-436

12 x 300 ml sample tubes or
10 x 500 ml sample tubes with the same instrument

Advantages of Buchi IR digestion:

Time savings due to short heat-up and cool-down times
Reproducibility thanks to homogeneous heat distribution
Use of 300 or 500 ml tubes with the same instrument
Simultaneous and even boiling of all samples
Fully sealed suction system for the removal of acid fumes

Outstanding features of the SpeedDigester K-425 and K-436:

High speed and throughput

An increased sample throughput is achieved thanks to the considerably higher heat transfer capability of infrared heaters as compared to contact heating sources. In addition, the heat-up and cool-down periods are considerably shortened. As a result, the total time needed for digestion is significantly reduced.

Excellent reproducibility

Reproducible results are achieved based on excellent and efficient thermal homogeneity for every sample tube due to the innovative isolation plate. The newly designed heating chamber which guarantees that the sample tubes are heated efficiently allows for optimal digestions without foaming.

Selection of sample tubes

The SpeedDigester accepts 300 ml as well as
500 ml sample tubes. The 300 ml sample tubes are suitable for Kjeldahl digestions for most samples, whereas the larger sample tubes are especially exciting in the field of environmental analysis since they allow for the use of larger sample volumes.

Highest safety standards

Safe operation and protection of laboratory equipment thanks to the tightly sealed suction system.

All acid fumes created during digestion are completely exhausted through the Scrubber B‑414 .

Special suction manifolds

Suction module standard: The mainly used suction module – appropriate for most applications.

Suction module with condensate trap: For aqueous samples – prevents back flow of condensate to the sample.

Suction module for H₂O₂: For fast H₂O₂ digestion – Min. 50% reduced processing time compared to conventional digestions, without heavy metal catalyst.

Accelerated digestion with H2O2

With the H₂O₂-digestion the processing time is shortened for at least 50%, compared to standard Kjeldahl digestion. H₂O₂in precence of sulphuric acid is speeding up the decomposition of organic material and a digestion is completed in about
30 minutes. Furthermore any foaming of samples is avoided. Due to the advantage that no heavy metal catalyst is needed, the application with H₂O₂ is more environment-friendly .

The suction module wich is especially designed for the addition of H₂O ₂enables for save addition of peroxide during digestion.
