CN2157521Y - Transparent test tube with ridgy inside surface of bottom - Google Patents

Abstract

The utility model relates to an improvement of the biological and medical test vector working tube. Five straight lines or spiral radiating carina are arranged on the inner surface of the lower part of the cylinder tube body of a universal outline test tube and the inner surface of a spherical tube bottom, and the central area of the tube bottom is still a spherical surface; the proposed structure not only increases the inner surface area of the low position of the pipe, but also increases the quantity of the reagent adsorbate of the inner surface; the optics performance of the tested object in the tube and the test performance of the radial are not affected.

Description

Transparent test tube with ridgy inside surface of bottom

The utility model relates to the improvement of biology, medical use test carrier instrumentation tubes.

The detection of existing biology or medical biotechnology sample, a lot of work are undertaken by the carrier instrumentation tubes, and this pipe abbreviates test tube as.The test tube of ordinary construction, material are with clear glass or plastic production, and body is thin walled cylindrical, and its upper end opens wide-mouth, and the bottom is spherical.Test is that ginsengs such as the sample of putting into pipe, reagent are mixed the color ratio of thing or the judgement of optics or ray performance.Amount of reagent in the pipe particularly must be adsorbed on amount of reagent or title package amount on the pipe bottom interior wall surface, and for example the ginseng that how much is determining reagent and sample of proteantigen body amount of reagent is mixed degree.The little reagent that adheres in inner wall surface of area is few, and the mixed combination rate of ginseng is low, and test result is not good, and greatly then the surface adsorption amount of reagent is many for area, and the reagent ginseng is mixed combination rate height, test result accuracy height.Therefore, near the size of the inner wall surface area at the end, directly influence the result of determination of sample.Moreover its shape also can influence its test result.

What have use on the market now is, the sphere bottom is provided with the cuvette of radial six interior oncus, this pipe compares with test tube at the bottom of the common sphere pipe, though having brought, the increase of bottom interior surface area adheres to the benefit that amount of reagent increases, the shortcoming of optics or ray refraction, diffusion loss had significant effects to measured value when but many oncus also can bring the increase test.

The purpose of this utility model is to design a kind of inner surface area that promptly increases the cuvette bottom stage, the biomedicine test tube that while oncus quantity and shape have good optical, ray performance again.

The purpose of this utility model adopts following measure to reach: five radial oncus are set on the inside surface of section at the bottom of the clear, thin-walled test tube, on the oncus position can be located at the bottom of the spherical pipe, also can be arranged at the bottom of the spherical pipe and the bottom of cylindrical pipe, oncus surface is with pipe internal surface and seamlessly transits, it is the straight radial state or the spiral radiation state at center that its oncus can be made into pipe sphere centre zone, the end, and its oncus distribution shape the best is evenly to distribute.

Accompanying drawing 1 is a test tube longitudinal profile synoptic diagram.Accompanying drawing 2 is the test tube top view.Description of drawings: 1, wide-mouth, 2, cylindrical pipe, 3, oncus, 4, at the bottom of the spherical pipe, 5, the central area.

Describe structure of the present utility model in detail below in conjunction with accompanying drawing: what embodiment shown in the drawings adopted is the test tube of universal standard profile, the test tube upper end is wide-mouth (1), the centre is cylindrical pipe (2), and the lower end is (4) at the bottom of the spherical pipe, and cylindrical pipe (2) external diameter nominal size is 12 millimeters.On the inner wall surface of (4) at the bottom of the spherical pipe in the lower end of test tube cylindrical pipe (2) bottom and pipe, be provided with five uniform be the radial oncus (3) at center with (4) central area (5) at the bottom of the spherical pipe, oncus (3) surface and (4) inner wall surface at the bottom of cylindrical pipe (2) inner wall surface and the spherical pipe, be rounding off, the inner wall surface of central area at the bottom of the spherical pipe (5) still is a sphere.The distance at (4) minimum position is not more than 15 millimeters at the bottom of the last spherical pipe of end distance of oncus (3).

The structural advantages that the utility model provides is, on the bottom stage inner wall surface of generic external shape size test tube, five oncus of setting have namely increased the ability of inner wall surface adsorbate, do not affect again in vitro measured object optics, ray test performance.

Claims (5)

1, a kind of biology, medical use cuvette, wide-mouth (1) is opened in the upper end, and the centre is a thin wall cylindrical body pipe (2), and the bottom is (4) at the bottom of the spherical pipe, and the end section inside surface of pipe is established radial oncus (3), it is characterized in that: establish five oncus (3).
