Field of the Invention The present invention relates to a silicone sheet laid on a shaking table of a shaking machine, and more particularly, to a sample container mounted on a silicone sheet with adhesion. The present invention relates to a sheet worn on a shaking base to prevent falling down and sliding movement of dispensing plates. 2. Description of the Related Art Sheets of this type are disclosed in Japanese Utility Model 2-3.
No. 0020 is known. This publication describes that a plastic sheet having an adhesive property formed by mixing a vinyl chloride resin with an adhesive additive is laid on a shaking table to adhesively fix a sample container. [0003] However, in addition to the problem that vinyl chloride resin volatilizes environmental hormone substances, there are various problems such as low heat resistance, chemical resistance, and a short product life. Further, since the conventional sheet does not have the fitting stopper frame, there is a problem that the dispensing plates, which are particularly lightweight and have a small contact area, slide during the shaking process and cannot be shaken. SUMMARY OF THE INVENTION The present invention relates to a process for hardening a silicone fluid, which has a low cross-linking density and a long penetrating distance (1/10 mm) between cross-links (1/10 mm).
A silicone sheet having excellent adhesiveness is formed by adjusting the hardness of the silicone sheet 20 to a low level, and a fitting frame such as a microplate or a deep well plate is provided on the upper surface of the silicone sheet and placed on a shaking table of a shaking machine. This problem was solved as a silicone sheet to be attached. DETAILED DESCRIPTION OF THE INVENTION In order to cure a silicone fluid such as silicone oil, for example, when an organopolysiloxane having vinyl groups at both terminals and side chains is crosslinked with polyhydrodienesiloxane, Lower density,
By increasing the distance between the cross-linked portions and adjusting the hardness to such a level as to have a shape-retaining force, the tackiness is richly generated. The hardness is measured by the penetration (1/1 /) shown in JIS K2207.
10 mm), 50 to 120, preferably 60 to 1
The hardness is adjusted to about 00. When the penetration is less than 50, the adhesiveness is lost, and when the penetration is more than 120, the shape retaining force as a sheet is lost. In addition, a filler such as white carbon may be added in an appropriate amount in order to increase the shape retaining force while maintaining the adhesiveness. Further, when the silicone fluid is vulcanized with benzoyl peroxide or the like, by appropriately adjusting the molecular weight and the crosslink density, it is possible to obtain a silicone sheet in a certain cured state having tackiness. [0006] In this way, a silicone processed body having rich adhesiveness is formed, and this is cut into a square having a constant thickness to form a silicone sheet 1 mounted on a shaking table 4. The silicone sheet 1 can be detachably fixed on the shaking table 4 without any means such as adhesion due to its tackiness. [0007] The silicone sheet 1 is formed in various types, large, medium and small, and as shown in FIG.
As shown in FIG. 3, the lower part of a light weight sample container having a small contact area with a sheet such as a microplate 3a for sample liquid dispensing, a deep well plate 3b, or the like, is pinched and stopped to prevent sliding movement. It is. FIG.
Is provided with a fitting frame 2 in which a silicone sheet 1 formed in half the size is laid on one half of the shaking table 4 and two dispensing plates are arranged on the other half of the shaking table 4 side by side. 2 shows an example in which the sheet 1 is laid and the shaking table 4 is efficiently used. Since the silicone sheet 1 exhibits almost the same adhesiveness from low to high temperatures, it keeps the sample container securely fixed under all temperature conditions of the shaking test, and degrades even at high temperatures up to about 200 degrees. It has excellent heat resistance and has chemical resistance to many chemicals used for testing. Adhesion does not decrease over time,
Even when soiled due to the adhesion of dust or the like, it can be returned to the initial state by washing with water. As described above, according to the present invention, a sheet to be laid on a shaking table with harmless silicone is formed.
The effect of shaking the sample liquid harmlessly and hygienically in a safe environment is produced. [0010] The adhesiveness of the sheet has the effect of preventing the object from falling down and sliding movement only by placing the sample container on which the sample is placed. Since the fitting frame is provided on the sheet, it is possible to surely prevent the sliding movement of containers such as a dispensing plate which is lightweight and has a small contact area.
