behrotest® Equipment for Sample Preparation in the
Determination of the Hydrocarbon Index IAW ISO 9377-2 or DEV H 53
behrotest® Extraction Unit
behrotest® PFL sample bottles are ideal for performing the
direct extraction in accordance with the new standard method. Moreover,
their solid glass stoppers offer a decisive advantage in safety and
The behrotest® separator facilitates the separation of the organic phase.
The components of the system are easily separated. This enables the user
to eqasily and quickly transfer the organic phase in one step to a
clean-up column. Moreover, the disassembled components are easily cleaned.
behrotest® Columns and Twin-stand for the Clean-up Step
The behrotest® clean-up columns with glass frit comply
exactingly with the ISO 9377-2 specifications.
The practical twin-stand provides secure support for two complete clean-up
units, each consisting of separation bulb, clean-up column and
Kuderna-Danish flask. Thus, the clean-up procedure can be simultaneously
conducted on two samples - without delays due to time-consuming equipment
or sample manipulation.
behrotest® Nitrogen Station for the Evaporative Concentration Step.
The two stage concentration of the organic phase is
concluded by evaporating the extract down to less than 1 ml under a mild
In the behrotest® nitrogen station, the nitrogen flow is led, by means of
two gas delivery tubes (each with independently adjustable flow regulator),
into the two Kuderna-Danish flasks. Thus, two samples can be
simultaneously evaporated by the ISO 9377-2 method.
