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 compared to conventional digestion systems. The SpeedDigester K-439 is also the world’s first IR digestion system with temperature control, so that exact temperatures can be set.
Features

K-425/ K-436: Manual IR digesters for 6 or 12 samples

  • Use of 300 or 500 ml tubes with the same instrument
  • 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.
  • The acid fumes produced are removed with the aid of the optional 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

K-436: two heating chambers that can be controlled individually

K-439: Automatic IR digester for 12 samples

  • The advantages of IR and block heating systems are now combined
  • Using modern application software, digestion methods (temperature ramps and time) can be programmed and saved in the database with a method name.
  • Graphical LC display which allows the user to observe the progress during a digestion as a graphical display. The three most recent digestion processes can be reviewed via the system’s memory function.
  • 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.
  • Exact temperature control: The exact temperature control makes it possible to maintain the set temperature; an aspect that contributes to excellent reproducibility.
  • Ease of operation: The user-friendly operating concept allows for simple programming and operation of the system. Up to 50 different time / temperature profiles can be stored under individual method names in the database. The 20 most commonly used methods are predefined in the SpeedDigester K 439 to simplify method development.
  • 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
  • Use of 300 or 500 ml tubes with the same instrument
  • 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 attached Scrubber B 414 which starts and stops automatically.
  • 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
