specific Embodiment approach 1

[0024] Specific embodiment 1: This embodiment is a dual-filament combination device for reagent exchange, storage and filtration, such as Figure 1-Figure 4 Specifically, it is composed of a first ring cover body 1, a first bottle body 2, a double threaded cover body 3, a second bottle body 4, a funnel 5, a second ring cover body 6 and a filter medium;

[0025] The inner wall of the first annular cover 1 is provided with internal threads, and the inner ring of the first annular cover 1 is a through-hole structure, and a sealing ring is arranged inside the first annular cover 1;

[0026] The inner wall of the second annular cover 6 is provided with internal threads, and one end of the second annular cover 6 is closed, and one end is open, and a sealing ring is arranged in the second annular cover 6;

[0027] Both ends of the first bottle body 2 are designed with open mouths, and the outer walls of the mouth of the two ends are provided with external threads;

[0028] The struc...

specific Embodiment approach 2

[0040] Embodiment 2: This embodiment is different from Embodiment 1 in that: the filter medium is film-like, mesh-like or omentum. Others are the same as the first embodiment.

specific Embodiment approach 3

[0041] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that: the sealing ring is combined with the first ring cover 1 by two-color injection molding; The injection molding method is integrated with the second ring cover body 6; the sealing ring is combined with the double-threaded cover body 3 through the two-color injection molding method. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a double pipe thread combined device for reagent exchange, storage and filtration and relates to a reagent exchange, storage and filtration device. The invention aims to solvethe technical problems that the conventional glass ware is not applicable to field operations and the connection manner and performance difficultly meet field sample collection and classification needs. The double pipe thread combined device disclosed by the invention is composed of a first cover body, a bottle body, a double thread cover, a funnel, a second cover body and a filtering medium, wherein the first cover body is an open cover; the second cover body is a closed cover; a group of internal threads is respectively formed in the upper part and the lower part of the inner wall of the double thread cover. The invention discloses a double pipe thread combined device for exchange, storage and filtration of reagents, powder and granules. The device comprises three parts, namely a bottlecover, a filtering medium and a bottle body. The bottle cover is divided into a closed cover, an open cover and a communicating port cover, different combination permutations are performed according to different experimental aims, aims of exchange, storage and filtration are achieved, the device can be used for biological culture and other purposes, and transformation among multiple functions canbe realized.

Description

technical field [0001] The invention relates to a device for reagent exchange, storage and filtration. Background technique [0002] At present, most of the experimental glassware products are used in the laboratory.
