Description

Description

Choose from basic units capable of handling just a few samples a day to fully automated systems for high sample throughput.

Benefits

  • Economy of chemicals, energy, labor, space and time
  • Efficient fume containment through optional exhaust manifold
  • Efficient fume removal through optional scrubber
  • Systems are compatible with Kjeltec™ Distilling Units
Standard Features
  • Three configurations available: auto lift, auto rack, and basic
  • System consists of a digestion unit and tube rack with capacity for either eight or twenty tubes
  • Audible “ready” or “cycle over” alerts advise user when digestion application is completed
  • Audible “alarm” alerts advise user when errors/interruptions occur within running application program
  • Unit is insulated to minimize heat transfer to the surroundings and allow fast, even heating
  • Auto versions have an integrated all-activity controller that is programmable using supplied software Auto models can be connected to a PC for datalogging and downloading of standard, user-defined applications

Basic Model

  • Temperature and time for digestion are selected on front panel; all other procedures are performed manually
  • Can be fitted with rack system at any time to save fume hood space
  • Cannot be upgraded to Auto model
Auto Lift Models
  • Fully automated digestion with user interface adapting to actual product configuration
  • GLP-support through two-way PC communication
  • Auto Lift models, with exhaust docking facility, allow fully automated unattended operation
  • Facilitate highly automated procedures, eliminating heavy and risky handling of hot chemicals; save fume hood space
  • When lift or scrubber unit is connected, they are controlled by the selected application program
  • Exhaust manifold docks automatically with the tube rack as the tubes move down into the preheated digestion unit; scrubber unit, if connected, starts
  • Scrubber capacity is automatically adjusted to contain fumes and minimize acid losses
  • When digestion is completed, the combined tube rack and exhaust manifold move to the cooling position with scrubber unit still running until no further fumes are evolved
  • Audible signal indicates “cycle over”
  • To avoid spillage, a drip tray is inserted under exhaust manifold after cooling
Auto Rack Models
  • Allow automated digestions but require manual placement of tube rack and exhaust manifold which are stored above the digestion unit
  • Can be upgraded to Auto Lift systems
Software for Auto Systems
  • Preinstalled software system controls all necessary functions of the unit
  • Additional PC application software has two-way communication with Digestion Unit via serial RS-232 cable (supplied)

For reflux chemistries, such as Chemical Oxygen Demand (COD), a reflux head connected to a cold water supply should be used in place of the exhaust manifold. For Kjeldahl digestions, the Scrubber Unit (TC2501-001) should be considered for neutralization of corrosive gases; this replaces the water aspirator. For most Kjeldahl digestions, straight 250mL tubes are recommended.
