What your adsorption lab actually checks
Pretreatment off the critical path
Degassing 3 or 6 samples in parallel while the analyzer measures removes the main throughput bottleneck — and consistent vacuum-and-heat prep is what keeps BET and pore numbers reproducible.

BELPREP VAC is a vacuum degasser for gas adsorption sample preparation — it removes adsorbed moisture and contaminants by vacuum and heat on 3 or 6 ports (VAC II / VAC III), so your BELSORP analyzer stays free for measurement.
What Is the BELPREP VAC: Dedicated Sample Degassing
Before a surface-area or pore-size measurement, samples must be degassed to remove water and contaminants that would otherwise skew the result. The BELPREP VAC does this on a dedicated station — vacuum and heat as standard, with an optional flow-and-heat mode — so pretreatment runs in parallel with analysis instead of tying up the analyzer. It comes in two models: BELPREP VAC II (3 ports) and BELPREP VAC III (6 ports). See full specifications below.

Why adsorption labs add the BELPREP VAC
Consistent degassing that keeps the analyzer measuring.
Parallel sample prep
Degas 3 or 6 samples at once while your analyzer measures — pretreatment stops being the throughput bottleneck.
Vacuum + heat to 450 °C
Standard vacuum-and-heat degassing to 430 °C (VAC II) or 450 °C (VAC III), ±5 °C; an optional flow-and-heat mode suits samples better prepared under gas flow.
Reproducible data
Proper degassing is what makes BET and pore results reproducible — a dedicated station does it consistently, independent of the analyzer schedule.
Companion to BELSORP
Pairs with BELSORP surface-area and pore analyzers so measurement throughput isn’t limited by on-instrument pretreatment.
