験の場合は極めて重要である。(Prior art and its problems) Microporous films are widely used in many fields as precision overuse materials. Particularly recently, in the field of biochemistry, it has become extremely common to pass a large number of samples in minute quantities at once in various micro-quantity tests for proteins, nucleic acids, etc., and for this reason, the overpass area of the overfill material is naturally extremely small. . For example, diameter 3-25
It has an overarea of about mm, and moreover, dozens or more samples are often passed through at once. In such cases, a filter with many over-open pores, so-called multi-filter, is often used, and at that time, a microporous film as a filter material is also attached to each over-open hole according to its size. Since it is troublesome to do so, a method that commonly covers all the over-open holes is often used. In this way, the installation of the overfill material into the overopen hole was only required by installing a single piece of microporous film, which greatly simplified the process.
On the other hand, leakage and smearing (cross-contamination) of excessive samples in the plane direction through the surface of this microporous film is likely to occur, and there is a risk that samples passing through each excessively open pore will mix with each other. .
Preventing such phenomena is extremely important, especially in the case of trace test.

Various measures have been taken, such as attaching a ring or flat seal to achieve a more complete seal, but the microporous film itself is porous and hydrophilic, so it cannot be used under normal tightening pressure. However, there is a problem in that leakage and bleeding (cross contamination) cannot be completely prevented.

The part of the microporous film 3 located in the bonded part with the plastic sheet 1 is made hydrophobic, and the part of the microporous film 3 located in the overly open pores 2 of the plastic sheet 1 maintains hydrophilicity. This is achieved by a microporous film laminate for multi-filter.

要であり、この微多孔性フイルム部分の微孔が消
失してもあるいは存在していても差支えない。 The microporous film 3 and the plastic sheet 1 can be laminated and laminated using thermal adhesion (including high frequency, ultrasonic adhesion, etc.) or adhesives, or for plastics, a solvent may be used. For films, there is a method in which a microporous film is immersed in a non-solvent chemical and then laminated directly onto a plastic sheet. In any of these methods, it is necessary that the bonded parts are in close contact and the microporous film part in this part becomes hydrophobic, and even if the micropores in this microporous film part disappear or do not exist. It doesn't matter if you do.

る。 When thermal adhesion is used, the originally hydrophobic plastic film is integrally fused and bonded to the hydrophilic microporous film, so the microporous film at the bonded portion becomes hydrophobic. When using adhesive,
The porosity of the microporous film part in the over-open pore area,
Care must be taken not to impair hydrophilicity, and on the other hand, it is necessary that the part of the microporous film located at the bonding area is hydrophobic not only at the bonding area but also at the surface of the film. When a microporous film is dipped in a plastic solvent (but not a solvent for microporous films) and laminated to the plastic film, the plastic melts and penetrates into the microporous film, making the lamination process difficult. The microporous film portion at the position becomes hydrophobic. In Figure 2, 3'
is a portion of the microporous film that has been made hydrophobic.

In this case, the aqueous solution is kept in the over-open pores in the natural state, and can be removed by pressurizing or reducing the pressure when necessary. Further, 23 is a guide hole communicating with a vacuum pump (not shown).
