  KJELCAT catalyst tablets

  Highly effective catalyst tablets for a wide variety of applications. Perfectly coordinated for use with C. Gerhardt digestion units. Available in packaging units of 1,000 pieces.
•  Anti-foaming tablets for strongly foaming samples
•  KJELCAT catalyst tablets, e.g. type Se, Cu, CuTi or Cu light


  Compact scrubber system for extraction and neutralisation of aggressive acid fumes.

  KT Eco Kit

  The KT Eco Kit, consisting of a thermoplate (available for KT 20 or higher) and fan, is the perfect enhancement for laboratories with a high sample throughput and modern energyefficiency standards. The plate covers the heated block, preventing unnecessary heat losses during the cooling phase. The additional fan significantly accelerates cooling of the samples even further. Both accessory parts are also available separately.
  •  Significantly accelerated cooling phase for samples enables quicker transfer to VAPODEST®

–  30 min. without equipment
–  20 min. with thermoplate
–  15 min. with fan
–  11 min. with complete KT Eco Kit*
•  The thermoplate keeps the heat in the block up to three times longer*
•  The thermoplate can be stored with the attachment on the block to save space
•  The fan, which is available individually, can also be used to reduce the block to an ideal starting temperature for the next digestion in the case of samples with a
     high water content.
