Exemplary safety during steam distillation

behr steam distillation apparatuses are not only highly efficient and reliable partners in everyday laboratory work. Safety of the user was also an important consideration during the development and construction of these apparatuses.

Therefore all steam distillation apparatuses are provided with

a protective (safety) switch as the main switch, which is automatically triggered in case of overloading and short-circuiting a mechanical excess pressure safety valve to prevent too high a pressure in the steam generator a vessel monitor (distillation is not possible without a vessel being inserted) A door contact switch, which switches the distillation apparatus off automatically when the door is opened a resettable excess temperature thermostat (in case of water deficiency in the steam generator) a cooling cycle monitor by means of a pressure switch temperature controlled steam heating phase and pressure control via a solenoid valve

Infrared digestion systems

The digestion units of the behrotest® InKjel series are fitted with a highly efficient infrared heater. The quality and positioning of the behr infrared radiator guarantees the user identical heating phases and digestion temperatures at all sample positions. This also applies to double row arrangement in sample racks for 12 samples. Direct sample heating by infrared radiator eliminates long heating up times with conventional heating block systems. The behrotest® InKjel is therefore an ideal fast digestion system for determination of nitrogen with the Kjeldahl method and for other high temperature digestion processes.

Steam distilllation apparatuses S 2, S 3, S 4 and S 5 are also provided with

an automatic heating current monitor for the steam generator

Steam distillation apparatus

behr steam distillation apparatuses of the S series are an optimum supplement to the InKjel fast digestion systems. Depending on requirements the user can choose between one manual and four automatic steam distillation apparatuses. These are identical in basic construction but differ in operating comfort and degree of automation.

All behr steam distillation apparatuses have the following common features:

efficiency and quickness practical suitability and user comfort exemplary safety and reliability favourable cost-effectiveness

Infrared fast digestion units

behrotest ® InKjel

Digestion units

Digestion units of the behrotest® InKjel series are fitted with a high power infrared heater. The quality and positioning of the behr infrared heater guarantees the user identical heating phases and digestion temperatures at all sample positions. This also applies to the double-row arrangement in racks for 12 samples. The glass digestion vessels are suspended in the rack and are not deposited on the bottom of the digestion apparatus. Therefore the digestion vessels are less susceptible to breakage than in an aluminium heating block. Direct heating of the samples through the infrared radiator eliminates the endlessly long heating times required using conventional heating block systems. High-quality quartz radiators, instead of the usual steel tubular heating elements, ensure particularly uniform heating at all sample positions. Therefore the behrotest® InKjel is the ideal digestion system for nitrogen determination with the Kjeldahl method and other high temperature digestion processes. In the Kjeldahl digestion the temperature is adjusted through the boiling point of sulphuric acid.

The basic units of the behrotest® InKjel series can accomodate racks for various vessel combinations:

6 reaction vessels of 250 ml in the InKjel 625 (M or P) 12 reaction vessels of 250 ml in the InKjel 1225 (M or P) 4 reaction vessels of 500 ml in the InKjel 450 (M or P) 4 reaction vessels of 750 ml in the InKjel 475 (M or P) The models of the InKjel P series have 10 freely configurable programmes for power and digestion time. behr one-button for extremely simple and fast programming. Menu designed in language of the country. If required the user can very simply convert his system for use with other glass sample vessels himself using various digestion cassettes (rack with fume extraction). The process extraction system behrosog 3 is used for extracting vapours during the digestion process. All InKjel systems are fitted completely with multi-level consoles, fume extraction unit, sample rack and glass digestion vessels.

The Weibull-Stoldt method

The quantitative fat content in a foodstuff is determined by extraction with a solvent The "free fat" is determined by direct extraction. The "total fat content" contains not only "free fat" but also the "bound fats", which are released by means of the acid digestion.

Extraction

The behr Range for Twisselmann Extraction

Extraction in Accordance with the Twisselmann Method

The Twisselmann method of extraction is a continuous high-temperature extraction. It functions in a similar way to Soxhlet extraction. However in the Twisselmann extractor the temperature in the sample is very hot, i.e. close to the solvent's boiling point. This improves solubility and reduces the extraction time. The extraction temperature is higher because the condensed solvent from above and the rising hot solvent vapour from below flow through the extraction thimble at the same time and mix there. The temperature of this mixture is a lot higher than that of the condensed solvent. The Twisselmann extraction time is up to 50% shorter than the Soxhlet extraction time.

behrotest ® Flow-through Unit

AQUABOX

The Aquabox flow-through unit enables the correct, expert determination of on-site parameters during the collection of ground water and sewage water samples. The unit permits the simultaneous determination of electrolytic and physico-chemical parameters under optimal and reproducible flow conditions. Aquabox is constructed of transparent, shock-resistant PETG, a thermoplastic copolyester. The transparent construction allows constant visual identification of problems during operation, e.g. sand or sediment contamination. All components which come into contact with water are made of non-wetting PETG (flow chamber and lid) or PP (inlet and outlet tubing). Therefore the water being sampled is not affected by any release of contaminants from the materials used for construction of the Aquabox. The lid is splashproof and easy to open and close by means of a quick-release fastener. The lid has 6 variable diameter, splashproof sensor holders for inserting sensors up to 25 mm Ø (larger diameters available on request). The water spirals upward in the chamber around the positioned electrodes and flows out over the splashproof outer housing Six holders in the lid with variable diameters provide secure sensor mounting in the peak flow area On-site measurements are made easy due to the rugged construction materials Water flow can be adjusted using a valve An inlet bypass valve allows sampling Aquabox is quick and easy to disassemble without the need for tools through a central threaded joint

Laboratory Sewage Plants

According to OECD 303 A (Coupled Units Test). Trolley mounted. All glassware is made of borosilicate glass 3.3, with pumps for water transport and aeration, flow meters and storage containers. KA 1 Laboratory sewage unit KLD 4 has an additional preliminary denitrification stage, in which activated sludge is held under virtually anaerobic conditions. In this way the sludge is denitrified and certain wastewater pollutants are more easily degraded. In combination with aeration, two stirrers prevent unwanted sludge deposits in the denitrification stage and in the aeration vessel. The operator can set the pumping and pause times for the return of the sludge to the denitrification vessel.
