behrotest® InKjel Infra-red Rapid DigestorsKjeldahl nitrogen determination

InKjel InKjel rapid Kjeldahl digestors with direct sample heating by infra-red radiation (1,500 W).

Configurations: 6 x 250 ml sample vessels
12 x 250 ml sample vessels
4 x 500 ml sample vessels
4 x 750 ml sample vessels

The 500 and 750 ml behrotest® InKjel units find application in water and wastewater analysis

The user can switch from one vessel size to another simply by replacing the vessels, vessel frame and fume manifold.

For InKjel Models 1225 P, 450 P and 475 P, the sample capacity can be doubled at modest price by addition of a cost-effective PE slave module, which is operated by the controller located in the InKjel P.

There are two behrotest® InKjel product groups::

  InKjel M Manual heating power control
  InKjel P Microprocessor control. Can store up to 99 digestion programs, each consisting of up to 10 power level-time intervals.

behr Kjeldahl Distillation Units

behr steam distillation units for Kjeldahl distillation accept InKjel M and P digestion vessels and are thus virtually indispensable for completion of the Kjeldahl procedure. The three models appear identical, but differ in levels of automation and operating convenience.

 S 1 Steam distillation unit, manual operation
  S 2 Steam distillation unit, programmable
  S 3 Steam distillation unit with automatic addition of H2O and NaOH. Dist. time 2-3 min.
 S 4 Steam distillation unit with fully automatic reagent addition and sample draining. Stores 99 programs. Dist. Time 2-3 min.
 S 5 Steam distillation unit, fully automatic, accepts external titrator (e.g. TB 1)

 

Exemplary safety during steam distillation

behr steam distillation units are not only efficient and reliable partners in everyday laboratory work; the user’s safety was also an essential concern during the development and design of the devices.

Therefore, all steam distillation units have

  • a circuit breaker as a main power switch which is automatically activated in the event of overload and short circuit
  • a mechanical pressure-relief safety valve to prevent too much pressure building up in the steam generator
  • vessel monitoring (distillation can only take place if a vessel is inserted)
  • a resettable excess temperature thermostat (in the event of insufficient water in the steam generator)
  • cooling circuit monitoring by means of pressure switches
  • temperature-controlled water vapour heating-up phase and pressure control by means of a solenoid valve

The S2, S 3, S 4 and S 5 steam distillation units also have

  • automatic heating current monitoring of the steam generator
