The Scentroid Vacuum Chamber is equipped with a powerful built-in sample pump capable of taking 12 lpm of sample even in negative pressure
The Vacuum Chamber comes with high capacity batteries that can be recharged using wall or automotive power plugs
The battery can sustain the sampling pump for more than 12 hours of continuous operation
Need a larger size? The larger models (VC25, VC50) both come with dual pumps for increased flow rate
Each vacuum chamber casing comes equipped with a large viewing window to see sample bag
Features built-in LED lights to illuminate the sample bag to ease filling operations
The purge function creates pressure within the sampling chamber, forcing all the air inside the sample bag through the sample line. This function makes purging, priming and conditioning an easy, one-step process.
The Vacuum Chamber Sampler (bag sampling chamber) uses a built-in miniature pump to create a vacuum of more than 18” HG inside the sample box. The 12V rechargeable battery is capable of sustaining more than 75 samples with a single charge and can be recharged using a 110/220V outlet or a 12V car outlet.
Open the vacuum chamber and connect the sample bag to the PTFE tube inside the chamber
Close the chamber and connect the external sample line to the sample collection device, or leave off to sample ambient air
Switch to the sample function to draw in the sample air. Stop when the sample is half full and switch to a purge routine to exhaust all lines
Switch to sample function again and fill the bag with sample air. Turn the unit off and open the case
Close the sample bag valve and remove it from the vacuum chamber sampler
Yes! The VCN is a special vacuum chamber designed for Nalophan bags. This rugged sampling equipment is easier to carry, deploy and use vs. the standard Plexiglass samplers traditionally used. For more information, please contact us directly.
The maximum sample rate of VC20 is 25 litres per minute.
If you require a sample rate lower than the maximum of 12 or 25 litres per minute, a flow regulator can be installed on the exhaust port of the instrument. Installing the exhaust port instead of the intake port will ensure the regulator is not contaminated with the sample.
Yes! We do make a special vacuum chamber that can be put on timers or be activated remotely via a smart app and GPRS connection.
For some sample bag materials such as Tedlar or nalophan it is critical to purge the bag, meaning to fill it halfway with the sample and then exhaust the air before taking the actual sample. In some countries, up to three purges are required. This process will ensure that any chemicals that would bind with the surface of the bag are completely eliminated, ensuring the final sample composition is unaffected. PTFE bags require less purging than nalophan or Tedlar.
