The small single chamber lysimeter is recommended for sampling down to approximately 5 feet (1.5 m). It has a bubbling pressure of 700 mbar.

One of the two 1/8" OD stainless steel outlets can be connected with tubing to a vacuum source, with a collection bottle in between. Vacuum can be supplied with the battery powered vacuum pump (G-144-SW-073).

For moist soil the optimal vacuum is about 300 mbar, but higher levels of vacuum may be used. The partial vacuum draws the fluid through the porous stainless steel walls of the lysimeter and up into a collection bottle.

The second outlet is opened at the end of sampling to empty the fluid lines. Sampling duration depends on the amount of sample required, the soil type, and the soil moisture content. Sampling times can vary from less than 1 hour in wet soil, to more than 1 day in drier soil.
