SMA-ARB

The workstations behrotest® SMA-ARB offer the complete basic configuration for heavy metal digestion with aqua regia in 6 or 12 samples simultaneously.

The components:

Precision heating block HMD with 6 or 12 sample positions for round digestion vessels with Ø 41.8 mm, temperature range 20 to 300°C

External controller ET 2, temperature range 20 to 450°C, time adjustable from 10 to 999 minutes or constant operation

6 or 12 round digestion vessels SR 2, 250 ml, with standard ground joint NS 29 and container ring made of PVDF

6 or 12 Ball reflux condensers SFK 50

6 or 12 Absorption vessels AS 1

Insert / yoke-type frame SG/B made of non-corrosive stainless steel for 6 or 12 reaction vessels

Basic frame with cooling water distribution and condenser holder for 6 or 12 sample positions

SMA-ARM

The workstations behrotest® SMA-ARM are equipped with a programmable, microprocessor-guided

controller in one to collect nitrose gases. For the user, this means more operating comfort and functionality in the daily laboratory routine.

Like SMA-ARB, however:

Instead of the control device ET 2 external microprocessor-guided controller TRS 300, temperature range 20 to 399°C, adjustable time from 1 to 999 minutes, comparison of reference and actual temperature or time during digestion, up to 25 temperature-time levels can be programmed and, in addition,

PTFE sleeves for glass parts

Insert / yoke-type frame SG/B made of non-corrosive stainless steel for 6 or 12 reaction vessels

Transport stand TS for sample preparation and sample transport

Basic frame with cooling water distribution and condenser holder for 6 or 12 sample positions

Hood AH for collection of nitrose gases of 6 or 12 samples, with connection possibility for suitable extraction and cleaning setup (e.g. behrosog 3)

• SR2 optimal heating of sample with special behrotest heating block & glass construction
• the SR2 have a collar made of PVDF. As a result, all reaction vessels can be inserted and removed in the block simultaneously. The PVDF collar keeps tension away from the glass vessel
• The NS29 ground joint connections have a large connection surface, which therefore provides a high degree of tightness between the reaction vessel and the condenser
• Th electronic control is separate from the heating block and therefore fully protected from aqua regia vapors outside of the extraction hood.
• Cooling is also possible by means of a recirculating cooler
• Each cooler is supplied individually with the same pressure and temperature of the cooling water, thus ensuring optimum cooling performance

Professional sample preparation for heavy metal determination

Precision heating and even & continuous cooling guarantee high recovery rates and exact analysis results

• Food analysis
• Environmental analysis - especially waste water & water
