The

compression inlet and outlet allows easy connection to the canister valve and
also to the tubing from the sample port. Several orifice sizes provide sampling times
from 4 minutes to 10 hours on a 6 L canister. Individual replacement parts are avail-
able, providing a cost-effective alternative to replacing the entire sampler.
This unique grab sampler is specifically designed for soil gas sampling by allowing
the connection of tubing coming from the soil gas sample port. The innovative design
minimizes connections and leaks and houses a critical orifice in the tee fitting. It also
incorporates a vacuum gauge and 2 µm frit filter.
