Grabner - Model AS Vision (ASV) -Autosampler
AS Vision (ASV) is an innovative autosampler that allows rapid and continuous testing of up to 12 samples, with a single press of the play button on MINIVAP VP Vision analyzers. It was developed to achieve the highest sample throughput for the most demanding vapor pressure methods.

- VP Vision’s Sampling ProTM valve design offers the lowest sampling volume of any vapor pressure analyzer. When combining AS Vision’s drastically reduced sampling circuit volume, fewer rinsing cycles are required – translating to increased efficiency regarding time and sample waste disposal
- Air saturated vapor pressure (ASVP) methods require the sample to enter the measuring chamber between 0C and 1C (32 – 34F). ASV’s external, liquid chiller connection ensures that sample warming / outgassing will not occur. Air bubbles that enter the measuring chamber have a direct impact on the result.
- A thermally optimized sample connection between ASV and VPV further prevents sample outgassing, prior to reaching the measuring chamber.
- Rugged chassis-mount design and optional VPV power inverter creates true portability, ideal for field use. Concealed, internal electrical connections to the analyzer promote mobile safety by eliminating snags on field obstacles. Optimize heavy workloads for mobile labs, refineries, independent labs, trading, transportation.
