Determination of the inorganic total fluoride FBA distillation unit behrotest® distillation unit to determine inorganically bound total fluorideIn highly contaminated inorganic wastewater with a fluoride ionic concentration greater than 0.2 mg/l determination of the inorganic bound total fluoride takes place after digestion and distillation. The behrotest® distillation unit combines all components required for distillation on a stable laboratory stand. The unit is also suitable for larger analysis series due to the heating control system.The single components are: Distillation equipment made of borosilicate glass for acid steam distillation, contact thermometer, heating mantles for distillation flasks and volumetric flasks.

behrotest ® homogenisers. With transportable sample vessels. Homogenisers for pre-treatment, splitting and homogenization of heterogeneous water samples in accordance with the quality assurance and quality control standards for wastewater examinations. The vessels of the homogenizers are protected against damage in the yolk type frame and can be carried easily by the two handles. They can be filled at the sampling location by a flattened inlet connection. Capacities from 2 to 25 l permit extraction and collection of multiple samples. Exact measurement of the sample quantities due to graduation. Subsequently, the transport rack is just placed on the magnetic stirrer in the laboratory or in the sampling vehicle and the homogeniser is immediately ready for use. The speed of the magnetic stirrer can be adjusted by a controller. The user can thus comply with the specified cone height in all cases. Oxygen is thus prevented from entering the samples. Dosed extraction of the homogenised sample via PTFE spindle stopcock. 12V, with adapter for mains connection.

Determination of hydrocarbon EX 1000 extraction unitThe PFL sampling bottle is ideal for direct extraction in terms of ISO 9377-2. With its solid glass stopper, in addition it offers a decisive advantage in handling and safety.The funnel separator facilitates the separation of the organic phase. The individual functional parts of the separator can be easily separated. The user can thus transfer the organic phase quickly and simply in one step to the clean-up column. In addition the individual functional parts are particularly easy to clean.

The complete equipment consists of:Tempering bath with thermostat for 6 eudiometer units incl. clamping device for eudiometer tubes6 eudiometer units with laboratory bottles, 500ml, eudiometer tubes with graduation, stopcock and connecting tube and levelling bulbSeries magnetic stirrer, for use in water bath to stir 6 bottles, each with 500 ml, including separate control unitSpecificationDims (WxDxH): Weight:850 x 330 x 360 mm 16 kg

Operating capacity 0 to 200%, corresponds to 0 to 19.9 mg/l Vessels made of borosilicate glass 3.3Other laboratory purification plants on request.

The injection of steam into the sampleguarantees a particularly gentle and uniform distillation. Steam is produced almost immediately (within maximum of 30seconds). The maximum period of steam injection depends only on the size of the externalcontainer.In WE 1 the distillation occurs only as a result of water vapourinjection into the sample.

The Aquabox flow-through unit enables the correct, expert determination of on-site parameters during the collection of soil and sewage 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 25mm diameter (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.Aquabox application areas:In the laboratory and on-site.In-line and point sample operation also possible.

The behrotest® clean-up column with glass frit corresponds exactly to the provisions of ISO 9377-2.The practical twin stand provides safe support for two complete clean-up units with dropping funnel, clean-up columns and Kuderna-Danish flasks. Thus, the complete clean-up procedure can be carried out for two samples simultaneously - without delays due to time-consuming equipment or sample manipulation.Clean-up-Station, supplied as: stand, 2 graduated round, bottom flasks, 100ml, 2 columns with grade 2 frits

The two-stage concentration of the organic phase is concluded by reducing the extract down to less than 1 ml under a mild nitrogen flow.In the behrotest® nitrogen station, a distributor leads the nitrogen flow via two individually adjustable tubes into the Kuderna-Danish flasks. Thus, two samples can be reduced simultaneously in accordance with ISO 9377-2.
