Description
Technical field
The utility model relates to a kind of test tubes, and in particular to a kind of EP pipe.
Background technique
EP pipe, also referred to as microcentrifugal tube, it is that consumptive material is commonly tested in Bioexperiment, is generally used to contain a small amount of
Liquid centrifugation, freeze-drying or stored sample.Existing EP pipe is many kinds of, for material, including glass material EP pipe,
The plastic materials such as polypropylene, polytetrafluoroethylene (PTFE) EP pipe；For specification, including 0.5mL, 1mL, 1.5mL, 2mL, 10mL, 50mL
Equal-specification；For type, including single tube, eight unions, 96 orifice plates.The pipe of the shell type EP as disclosed in CN206778461U, including
Tube body and Guan Gai further include a pipe sleeve, have pipe sleeve wall portion and a pipe sleeve bottom, setting above the tube body on the inside of spout part, and with
Spout part is connected, and the outer diameter of the pipe sleeve matches with the spout part internal diameter；It is provided with cylindrical boss on the inside of the pipe lid,
The cylindrical boss outer diameter matches with the clear internal diameter, and when pipe lid is placed on tube body, the cylindrical boss is set in
In the pipe sleeve, the pipe lid is connect by interconnecting piece with tube body.For another example a kind of new E P pipe, packet disclosed in CN205590686U
EP tube body and screw thread are included, the height of the screw thread is 0.1mm, width 0.5mm, and is spirally distributed in EP bottom of the pipe two
On/mono- inner wall.
During Bioexperiment, when being used to contain the liquid such as reaction solution, developing solution, water with the EP pipe of glass material, usually
There are liquid to there is the phenomenon that concave surface in EP pipe.The reason is that liquid is mutually infiltrated with EP inside pipe wall, liquid and EP inside pipe wall it
Between molecule affinity it is big, liquid can be attached to EP inside pipe wall surface well, and be unfolded to extend along EP inside pipe wall, thus in EP
Inside pipe wall forms concave surface.And when the material of EP pipe is the tetrafluoride material such as polytetrafluoroethylene (PTFE), tetrafluoroethene, reaction solution, developing solution,
Molecular repulsion power between the liquid such as water and EP pipe is big, and liquid cannot be attached to EP inside pipe wall surface, liquid along EP inside pipe wall to
Lower contraction, causes liquid concave surface occur in EP pipe.Since EP tube capacity amount is smaller, the liquid of splendid attire occur in EP pipe concave surface or
Convex surface will affect the accuracy that EP liquid in pipe volume data reads (reading), read number in particular by the mode of non-head-up
According to when, often will cause biggish error.
Utility model content
The purpose of this utility model is to provide a kind of EP pipes to subtract simultaneously in order to read EP liquid in pipe volume data
Small EP liquid in pipe volume data reading error.
To achieve the goals above, the utility model uses technical solution as described below.
A kind of EP pipe, including tube body and Guan Gai, are provided with the data markers for quantitative volume, feature exists on tube body
In: bar shaped convex part is axially provided in tube body and along tube body, and convex part is located at the positive opposite side of data markers.
Above-mentioned technical proposal utilizes convex lens image-forming principle, can not only amplify data markers and EP liquid in pipe, thus
Convenient for reading data, and data read error can be reduced.
Further, for convenience of reading EP liquid in pipe volume data, while reducing the reading of EP liquid in pipe volume data
Error, being provided in convex part can be along tube body cross cursor part in axial sliding.
Further, it is provided with hollow portion in convex part, cross cursor part is equipped in hollow portion, in cross light
It is provided with telescopic rod on tender, and realizes sliding up and down for cross cursor part by sliding up and down telescopic rod.
EP liquid in pipe volume data is read to further facilitate, above-mentioned cross cursor part is wide compared with data markers scale.
Preferably, the color of above-mentioned cross cursor part is identical as the color of data markers.
Preferably, the center thickness of above-mentioned convex part is 2-3mm, the width of convex part is 5-10mm.
Further, above-mentioned convex part is made using rock crystal material.
Further, data markers corresponding with the data markers on tube body are set on convex part.
Technical effect: the utility model EP pipe utilizes convex lens image-forming principle, can put data markers and EP liquid in pipe
Greatly, consequently facilitating reading data, reduces reading data difficulty, correct in conjunction with cross cursor part and the registration of data markers
Data reading mode when reading data in particular by the mode of non-head-up, is easy discovery mistake by means of cross cursor part
Reading manner helps technical staff's correction according to reading manner, and can extremely accurate read EP liquid in pipe volume data, subtracts
Small data reading error.In addition, the utility model EP pipe structure is simple, and it is easily fabricated, it is easy to use.
