Product Detail

Vacuum bag sampler provides fast sampling with zero cross-contamination. The sampler allows sample bags to be filled directly by using negative pressure. It can be used to collect volatile organic compounds (VOCs) and other gaseous samples from fixed pollution sources and ambient air.

We have two models:

ZR-3520 Vacuum bag sampler(for fixed pollution sources and ambient air)

ZR-3730 Vacuum bag sampler(for fixed pollution sources only)

Applications

> Industrial VOCs

> Indoor air quality

> Effluent gas samples

> Stack sampling

> Ventilation studies

> Hazardous Material (HazMat) testing

Features

> One button operation. Cleaning and replacement automatically, no need to plug or unplug the bag.

>  Built-in battery≥12H.

>  Protects sample pump from contamination

    • Sample does not pass through the pump

    • Sample contacts only inert tubing and bag. Ensure that the collected samples are free from contamination and adsorption.

>  Rugged heavy-duty, airtight construction.
