Abstract

A support bracket ensuring the visible liquid level and the placing stability of a PCR (polymerase chain reaction) tube relates to a support bracket for the PCR tube, and solves the problems that being shielded by the conventional support bracket, the liquid level in the PCR tube is not visible, and the placing stability of the PCR tube is poor. N through holes are uniformly formed on a PCR support plate; each through hole and two baffle plates fixedly embedded in the through hole form a PCR tube slot; the internal diameter at the upper end of the PCR tube slot is the same as the diameter of the PCR tube; the internal diameter at the lower end of the PCR tube slot is smaller than the diameter of the PCR tube; two groups of support frames are fixed below the PCR support plate in parallel; and N is a positive integer. The support bracket is suitable for bearing various types of 0.2 ml PCR tubes.

Description

Liquid level is visual and place stable PCR pipe Support bracket

Technical field

The utility model relates to a kind of PCR pipe Support bracket.

Background technology

At present, be used for PCR pipe Support bracket and all have the end and shirt rim, the liquid level of PCR liquid in pipe is blocked, and the liquid level visibility is relatively poor; And the aperture in the holder hole of existing P CR pipe Support bracket is bigger, and after the PCR pipe was put into, the PCR pipe had the space with the holder hole medial surface of Support bracket, and PCR pipe placing stability is relatively poor.

The utility model content

The utility model is to be blocked by PCR pipe Support bracket and cause liquid level not visual in order to solve PCR intraluminal fluid face, and the problem of PCR pipe shelf-stability difference, thereby provides a kind of liquid level visual and place stable PCR pipe Support bracket.

Liquid level is visual and place stable PCR pipe Support bracket, and it comprises PCR back up pad and two groups of bracing frames, evenly has N through hole on the said PCR back up pad; Each through hole all constitutes a PCR pipe slot with two baffle plates that are mounted in this through hole; The upper-end inner diameter of said PCR pipe slot is identical with the caliber of PCR pipe; The bottom diameter of PCR pipe slot is less than the caliber of PCR pipe; Two groups of bracing frames be fixed on the PCR back up pad below, and two groups of bracing frames are parallel to each other; N is a positive integer.

Two of build-in baffle plates are symmetrical set in each through hole, and plane, the symmetry axis of two baffle plates place is vertical with plane, PCR back up pad place.

The PCR pipe slot that is positioned at PCR back up pad bottom is 1: 1 with the ratio that the PCR that is positioned at PCR back up pad top manages slot.

Beneficial effect: the utility model adopts the no end not have the design of shirt rim, and the liquid level of the liquid in the PCR pipe is not blocked, and liquid level is visual; And the upper-end inner diameter of the PCR pipe slot of the utility model is identical with the caliber of PCR pipe, and the PCR pipe closely is connected with PCR pipe slot inwall, and PCR pipe shelf-stability is high.

Description of drawings

Fig. 1 is the structural representation of the utility model; Fig. 2 is the vertical view of the utility model; Fig. 3 is the structural representation of a PCR pipe slot among Fig. 1; Fig. 4 is the structural representation with reference to the PCR of frame pipe Support bracket that has alphanumeric indicia described in the embodiment four.

Embodiment

Embodiment one, combination Fig. 1 to Fig. 3 explain this embodiment, and liquid level is visual and place stable PCR pipe Support bracket, and it comprises PCR back up pad b and two groups of bracing frame c, evenly has N through hole on the said PCR back up pad b; Each through hole all constitutes a PCR pipe slot a with two baffle plates that are mounted in this through hole; The upper-end inner diameter of said PCR pipe slot a is identical with the caliber of PCR pipe; The bottom diameter of PCR pipe slot a is less than the caliber of PCR pipe; Two groups of bracing frame c be fixed on PCR back up pad b below, and two groups of bracing frame c are parallel to each other; N is a positive integer.

In this embodiment, PCR back up pad b is processed by higher materials of flintiness such as Vestolen PP 7052 PP and polycarbonate, and surfacing is smooth, and non-deformability is strong; In the preparation, under 121 ℃ temperature, carried out autoclave sterilization 20 minutes; After the preparation, b identifies to the PCR back up pad, pollutes to guarantee human DNA, DNase, RNase and PCR suppressor factor.

This embodiment adopts the no end not have the shirt rim design, guarantees that the liquid level of PCR pipe is high-visible, and the PCR pipe leaks application of sample or wrong application of sample, and is all visual in real time.

This embodiment can be realized a plurality of the utility model are stacked together.

The difference visual and that place stable PCR pipe Support bracket of embodiment two, this embodiment and embodiment two described liquid levels is; Two of build-in baffle plates are symmetrical set in each through hole, and plane, the symmetry axis of two baffle plates place is vertical with plane, PCR back up pad b place.

The difference visual and that place stable PCR pipe Support bracket of embodiment three, this embodiment and embodiment one or two described liquid levels is, the PCR pipe slot a that is positioned at PCR back up pad b bottom is 1: 1 with the ratio of the PCR pipe slot a that is positioned at PCR back up pad b top.

Be positioned at PCR back up pad b top PCR pipe slot a be 3.7mm, coincide with the caliber of the PCR pipe of 0.2ml, make the PCR pipe put stable.The internal diameter that is positioned at the PCR pipe slot a of PCR back up pad b bottom is 3.46mm, guarantees that the PCR pipe can not come off from the bottom that PCR manages slot a.

The difference visual and that place stable PCR pipe Support bracket of embodiment four, this embodiment and embodiment three described liquid levels is N=96.

This embodiment is 96 a hole PCR pipe Support bracket, can carry maximum 96 PCR pipes.And have unique oblique type corner and alphanumeric indicia with reference to frame, as shown in Figure 4, realize PCR managed identifying.
