Determination of total protein content: 

Determination of Kjeldahl nitrogen 

The behr equipment for determination of Kjeldahl nitrogen offers the user a complete 

individually configurable solution for the laboratory. 

• Sample Digestion Units 

The sample digestion units of the behrotest® InKjel line are provided with 

powerful infra-red heating elements. 

The quality and positioning of the infra-red heating elements guarantee the user 

reproducible heating phases and digestion temperatures at all sample positions. 

This also pertains to the twelve sample digestion unit, in which the samples are 

arrayed in two rows of six each. 

Direct irradiation of the samples by the infra-red sources eliminates the painfully 

slow warm-up phase associated with conventional heating block units. 

InKjel 625 M 

Thus, the behrotest® InKjel is the ideal rapid digestion unit for the Kjeldahl 

nitrogen determination and other high temperature sample digestions. 

• Steam distillation units 

The behr steam distillation units of the „S“ model series are the optimal 

complement to the InKjel rapid digestion units. 

Depending on the user’s requirements, he may choose between one manual and 

two automatic steam distillation models. These are similar in concept, but differ 

in the level of automation and convenience features. The top-of-the-line model, 

the behr S 5, is designed to accept an external titrator. 

All behr steam distillation units have the following common features: 

— Powerful and fast 

— Practical and user-friendly 

— Exemplary safety and reliability 

— Sturdy chemically resistant stainless steeel housing 

— Practical quick-release vessel clamp permits easy use with right or left hand 

— Especially simple menu-driven operation of the programmable apparatus by 

means of one single control knob 

InKjel 625 P 

• Fume exhaust system 

The two-stage behrosog fume exhaust system – condensate trap plus 

neutralization stage – keeps all acid fumes completely out of the environment. 

• Titration stations 

The behrotest® STI manual titration station or an automatic titrator provide for 

reliable, safe and rapid titration into complete the nitrogen determination.

ehrotest ® InKjel Infra-red Rapid Digestion Units 

The basic units in the behrotest® InKjel model series hold insertable frames for different combinations of vessels: 

• 6 reaction vessels with 250 ml capacity in InKjel 625 (M or P) 




If required, the user can re-equip his system himself very easily with different digestion boxes (insertable frame with suction 

extraction apparatus) for other sample glassware. 

The behrosog process suction system is available to extract vapours during digestion. 

All InKjel systems are completely equipped with tiered console, suction system, insertable frame and digestion glass vessels.

Soxhlet Extraction 

The standard method for the determination 

of free fat in foodstuffs is the Soxhlet extraction. 

behr equipment for the extraction fulfils 

the most varied requirements of daily 

laboratory use. 

• Extractor sizes from 30 to 250 ml. 

• Kompakt units for single sample 

processing. 

• Heating block units with especially 

exact temperature control for 

simultaneously processing up to 

6 samples. 

• Extraction systems for four or six 

samples with linear configuration of 

individual extrators. 

• Extractors with a specially developed 

siphon tube guarantee uniformity of 

extraction in all sample positions. 

• Extractors provided with spigots 

for draining solvent obviate need to 

distill solvent before reuse. 

• No rotary evaporator is required. 

Use of the hydrolysis glassware kit 

(for 1, 4 or 6 sample units) enables acid 

digestion to be performed prior to extraction 

in accordance with the Weibull 

and Stoldt method for determination of 

total fat content.
