Description

Combined device for filtering sample

Technical Field

The utility model relates to a chemical industry field, concretely relates to sample is at filtration and transfer device between container.

Background

The sample is transferred from the first container to the second container, during which the sample needs to be filtered. However, the filter paper has a small filter hole, and if the operator places the filter paper at the entrance of the second container and pours the sample in the first container directly onto the filter paper, the sample does not immediately pass through the filter paper into the second container, but remains on the filter paper and overflows all around.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: a combined device is designed, and a sample in a first container can enter a second container after being filtered by filter paper.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a composite set of sample filtration usefulness, including first container, the second container, the connecting piece, a clamp, filter paper, the entrance of first container is equipped with first centre gripping edge, the head end of connecting piece is equipped with second centre gripping edge, the entry of first container docks with the head end of connecting piece, the tail end of connecting piece docks with the entry of second container, filter paper is by the centre gripping between the entry of first container and the head end of connecting piece, the first centre gripping edge of clamp centre gripping and second centre gripping edge, be equipped with the connector of being connected with evacuating device on the lateral wall of connecting piece.

The sample in the first container needs to be filtered through filter paper and transferred to the second container. Firstly, the first container is upright on the working table, the inlet of the first container is covered with filter paper, and the head end of the connecting piece is pressed against the inlet of the first container to press the filter paper. Thereafter, the clip grips the first gripping edge and the second gripping edge, and the first container and the connecting member are fixed together. The inlet of the empty second container is then mated with the trailing end of the connector. And then, the first container, the connecting piece and the second container which are matched together are arranged upside down, and the first container, the connecting piece and the second container are arranged from top to bottom in sequence, and at the moment, the second container is upright on the working table. And then, the connector of the connecting piece is connected with a vacuumizing device, the vacuumizing device vacuumizes the connecting piece and the second container which are matched together, so that pressure difference is formed on two sides of the filter paper, and the sample in the first container flows into the second container through the connecting piece under the dual action of gravity and the pressure difference.

The utility model discloses the transfer efficiency to the sample after needs are crossed the filtration has the raising effect.

Detailed Description

With reference to fig. 1 and 2, a combined device for sample filtration comprises a first container 10, a second container 20, a connecting member 30, a clamp 40 and filter paper 50, wherein a first clamping edge 11 is arranged at an inlet of the first container, a second clamping edge 31 is arranged at a head end of the connecting member, the inlet of the first container is in butt joint with the head end of the connecting member, a tail end of the connecting member is in butt joint with an inlet of the second container, the filter paper is clamped between the inlet of the first container and the head end of the connecting member, the clamp clamps the first clamping edge and the second clamping edge, and a connecting head 32 connected with a vacuum extractor is arranged on a side wall of the connecting member.

The first container 10, the second container 20 and the connecting piece 30 are all glassware. The process of sample transfer is visible.

The second container 20 is a conical flask, the inlet of which is a straight cylinder, and the tail end of the connecting piece 30 is also a straight cylinder, and can be directly sleeved on the inlet of the second container.

Referring to fig. 3 and 4, the clip 40 includes an upper clip 41 and a lower clip 42, which are hinged by a hinge shaft 43, on which a torsion spring is sleeved; the upper clamp and the lower clamp are both provided with openings 44, and the edges of two sides of the openings are provided with clamping edges 45. The function of the notch is to allow the neck of the first container, and thus the neck of the connecting element, to be located. The clamping edge is used for clamping the first clamping edge 11 and the second clamping edge 31, so that the first container and the second container are fixedly connected. As a modification, the

handles

46 and 47 of the upper and lower clamps are bent, and the bending angle of the handle of the lower clamp is larger than that of the handle of the upper clamp. So, the operator displaces two handles in opposite directions, and it has great clamp mouthful with lower anchor clamps to go up to press from both sides to adapt to the first centre gripping edge and the second centre gripping edge that the size is different.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
