Definitions

  • liquid-flow contact means, in sufficient proximity such that a liquid meniscus emanating from surface 26 will also wet material 28 and flow into it, if no air lock exists in the lower compartment.
  • Material 28 is any bibulous material, having a sufficient pore volume to soak up about 2 cc of liquid.
  • Useful materials include cellulose acetate, cotton, and rayon.
  • Useful materials for filters 24 include polyamides, such as nylons, and for example nylon-66 microporous membranes manufactured under the tradenames BIODYNE A or ULTIPOR N-66 by Pall Corporation. Most preferably, the membranes are precoated (prior to use) with one or more water-soluble proteins, such as casein derivatives obtained from acylation, alkylation or sulfonylation of the casein.
  • the noted properties for the elastomeric material are preferably within the following ranges: Durometer (a measure of hardness) of no greater than about 70 Shore A, and most preferably from 55 to 65 Shore A.
  • Cold flow (a measure of loss of recovery after being deformed, also known as "compression set") of between about 10 and about 40% lost recovery when compressed at 25°C, and most preferably, 23% lost recovery.
  • a specific gravity of from 0.95 to 1.0 a tensile strength of from 45 Kg/cm2 to 70 Kg/cm2, ultimate elongation of from 300% to 400%, a 100% modulus value of from 20 to 25 Kg/cm2, a tear strength at 25°C of from 19 to 25 kN/m, a tension set of from 5 to 10%, flex fatigue to failure that is greater than 3.4 million, and a brittle point less than 60°C.
  • Device 10 is not a large device, having a length for valve 50, Figure 2, and thus for the entire device, of no more than about 6.5 cm.
  • a length for valve 50, Figure 2 and thus for the entire device, of no more than about 6.5 cm.
  • the elastomeric member can comprise at least the surface portion 46 of stud 47, Figure 4, with the member 56 being formed of a relatively rigid material, for example, polystyrene. In that case, it is the surface portion 46 that is preferably compressed distance "d" when the slide valve is on the studs.
