FEATURES
This injection molded outer elastomer casing
and tough interior porous ceramic cup make it a great combination. The
elastomer protects the ceramic from damage and adjusts to applied pressures
while the porous ceramic provides an easy interface for water pushed
from the sample. A sandwiched coarse nylon screen provides a continuous
drainage path for the water. The enormous interior surface area of the
cup makes it an ideal receptacle for large prepared samples that must
reach equilibrium quickly, reducing waiting times by factors of 10 or
more in many cases. All parts are nonmetallic, permanently joined, and
free from possible contamination from volatile sealants or compounds.
typical applications The 0685 Series are generally used for the quick
determination of soil moisture retention values. The development of
a moisture retention curve is much easier and accurate with a cup assembly
that can be removed and weighed without disturbing the sample. The large
interior ceramic surface areas assure reaching equilibrium in the fastest
time possible. Of course, the adaptable unit can be used in the extractor
for pressure extractions of pastes and thick solutions or outside the
extractor for stand alone, weighable, suction environments for seedlings
and other small plants.
