Components for extraction

The LABSOLUTE® reflux condensers are made of high-quality borosilicate glass 3.3 and comply with the common valid standards. You can choose between condensers according to Allihn, Dimroth and Liebig in several lengths and with different socket and cone connections. The water connection goes via a GL14 screw thread in combination with PP olives or via simple glass olives. All reflux condensers have a very good chemical resistance and a high temperature resistance. You can use our LABSOLUTE® condensers for distillation, chemical synthesis, and many more laboratory applications.

The LABSOLUTE® Dimroth condensers for Soxhlet application comply with DIN 12591. Water connectors with GL14 thread.

The LABSOLUTE® funnel holders are made of PP for all types of laboratory funnels with a diameter up to 150 mm as well as separating funnels. A clamp adapter is provided for use with rods from 8 to 12 mm.

Supplied with PTFE stopcock. With PE conical stopper.

• ISO 4800
• NS necks according to DIN 12242 standard

Soxhlet extraction stillheads, made of DURAN^® tubing. Extractor heads acc. to DIN 12602 and in addition to DIN standard (*).

Made of DURAN^® tubing. For extractors and for condensing vapours. With cone. Water connection with thread GL14, with two threaded PP olives.

Made of DURAN^® tubing. For condensing vapours. With cone, water connection with GL 14 thread and two threaded plastic olives.

Made of DURAN^® tubing. Distribution tubes with frit (porosity: 0), for specific heavy solvents.

Made of DURAN^® tubing. For the extraction of liquids with specific heavy solvents, with insert filter (porosity: 0).

Extractor heads for the extraction of liquids with specific light solvents, with insert filter (porosity: 0), made of DURAN^® tubing.
Distribution tubes with frit (porosity: 0), for specific light solvents, made of DURAN^® tubing.

The condensate passes the extraction sample and flows back into the flask continuously without interrupting the extraction process, i.e. the solvent is recirculated continuously.
The complete apparatus consists of:
Jacketed extractor head made of DURAN^® tubing, Dimroth condenser with thread GL 14, made of DURAN^® tubing,
Round bottom flask material: DURAN^®

Manufactured from borosilicate glass 3.3. Suitable for xylol method. System completed with 500 ml (NS 29/32) flask + Liebig condenser with jacket length 400 mm + measuring tube (10:0.1 ml) with PTFE stopcock.

Acc. to DIN 12420 (xylol method), capacity: 10:0,1ml, with round bottom flask 500ml, measuring tube and condenser made of DURAN^® - tubing, flask: DURAN^®.

Complete compact extraction systems with stand, heating module, mount, hoses and glassware (round-bottom reaction flask, extractor, Dimroth condenser for extraction). Infinitely variable heating regulation.

• practical stand for holding the condensers securely between extractions
• extractor sizes from 30 ml to 5000 ml
• the use of extractors with a stopcock eliminates the need for any additional distillation after extraction
• Condensers with screwed-on tubing nipples

Determination of the inorganic total fluoride FBA distillation unit behrotest^® distillation unit to determine inorganically bound total fluoride

In 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.
