MONOFLEX^TM POROUS CERAMIC LYSIMETERS

MONOFLEX'S^TM Porous Ceramic Lysimeters are constructed similar to the MONOFLEX^TM Porous Teflon® Lysimeters. Advanced machining techniques allow the ceramic filter to be threaded. This permits, for the first time, a totally adhesive and sealant free construction. Sealants, potential sources of contamination, are eliminated. The MONOFLEX^TM Ceramic Filter Elements have a pore size of 0.446 micrometers by the mercury penetration porosimetry method (ASTM C-699).

The MONOFLEX^TM Porous Ceramic Filter element may be easily removed from the body for decontamination or replacement if accidental breakage occurs. MONOFLEX^TM uses Viton® O-rings in the flush threaded ceramic joints, to ensure a leak-free seal. The top plug is threaded to allow attachment of casing. If the lysimeter unit is located more than 20' (6M) below the ground surface, a MONOFLEX^TM Deep Sampling Lysimeter will be required. Sample recovery in excess of 10 psi may damage the filter and/or silica pack and force the collected pore water sample out of the lysimeter, back into the soil. MONOFLEX^TM recommends the use of its Select Silica Flour as a pack around the installed lysimeter. Cup type available in 1.9" O.D. x 17.5" length.
