Workstations for SMA ARB
Workstation model SMA-ARB
The behrotest
® workstation model SMA-ARB is a basic system for simultaneous aqua regia digestion of either 6 or 12 samples for heavy metals analysis.
System components:
- Precision 6 or 12 sample SMA heating block for round-bottom sample vessels of Ø 41.8 mm, temperature range 20 to 300 °C.
- External ET 2 controller, operating range 20 to 399°C. Time settings from 10 to 120 min. and continuous operation.
- 6 or 12 SR 2 250 ml round-bottom sample vessels with standard taper mouth and PVDF collar.
- 6 or 12 RFK 1 Allihn reflux condensers.
- 6 or 12 AS 1 absorption vessels.
- SG/B stainless steel vessel holding frame for 6 or 12 sample vessels.
- Support scaffold with cooling water distributor and storage holder for 6 or 12 condensers.
behrotest® Multi-sample Extractors for Twisselmann Extraction
Economical and user-friendly units for extraction in accordance with Twisselmann:
- each sample position is individually adjustable
- cooling water distributor ensures an even cooling at all sample positions
- practical stand for holding the condensers securely between the extractions
- mounts for holding the spacers after the removal of the sample containers
Complete compact extraction systems, with heating
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
Extraction thimbles, Borosilicate glass
Recommended for Soxhlet extraction with solvents, which are incompatible with cellulose fibres and for filtration of air and gas streams.
- Made of 100 % pure borosilicate fibres, without binding elements
- High loading capacity and highly permeable to air
- Thickness is 1.5 mm (diameter < 33 mm)
- High retention of small particles, > 99 % according to BS 4400
- Good stability at high temperatures up to 500 °C
- Recommended for hot, moist, and acidic gases
- Gravimetric determination of particles in hot gases
Extraction Thimbles, cellulose
For reliable and fast analysis in the areas of food control and environmental monitoring. Suitable for Soxhlet-type, Tecator-type or similar devices, to extract certain components out of solid material with an appropriate solvent.
- Made of pure cellulose that is totally free from binding elements
- High purity of selected cellulose guarantees reliable and replicable results
- The consistent high porosity ensures fast flow through
- High fitting accuracy for all available extraction systems
- Wall thickness 1.3 mm at thimbles with ≤35 mm inner diameter, 1.7 mm at thimbles with >35 mm inner diameter
- For two systems
- Grade 900: Soxhlet Extraction, Grade 901: Tecator Extraction
