Abstract
The utility model discloses a measuring device of the height of liquid nitrogen in a liquid nitrogen container, and the measuring device comprises a vacuum ball and a graduated tube, wherein a thread hole is arranged at the upper part of the vacuum ball so as to be connected with one end of the graduated tube; the graduated tube is provided with scales; and after the vacuum ball is connected with the graduated tube, the height is higher than that of the liquid nitrogen container. The utility model designs the novel measuring device of the height of the liquid nitrogen; and the graduated tube is arranged outside the liquid nitrogen and the influences of temperature are smaller, so that the position of a liquid level can be accurately measured. Meanwhile, when the liquid level of the liquid nitrogen is reduced, the vacuum ball is fixed at the bottom of the container, so that the liquid level of the liquid nitrogen is raised to submerge stored objects, and cryopreservation of cells can be finished in time.
Description
Technical field
The utility model relates to cell freezing and preserves the field, relates in particular to a kind of measurement mechanism that is used for the liquid nitrogen container liquid nitrogen height of cryopreservation cell.
Background technology
In cell cultivation process, in order to preserve cell, be with cell cryopreservation.Frozen temperature is generally used the temperature one subzero 196 ℃ of liquid nitrogen, and is frozen with certain cooling velocity with adding the nutrient culture media that contains protective agent (being generally dimethyl sulfoxide or glycerine) in cell harvesting to the frozen pipe, finally is stored in the liquid nitrogen.
Traditional liquid nitrogen container can't be measured its liquid level, does not know when to carry out replenishing of loss liquid nitrogen, can influence the effect that cell is preserved.Use scale in the time of generally will measuring the liquid nitrogen height, but scale takes out from liquid nitrogen, stroke is than the large tracts of land frost at once, and can receive the influence of liquid nitrogen cryogenics, can't measure liquid level accurately.
The utility model content
To above defective, the utility model provides a kind of liquid nitrogen height measuring device, solves the problem that present liquid nitrogen container can't accurately be measured inner liquid nitrogen height.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
The measurement mechanism of liquid nitrogen height in a kind of liquid nitrogen container comprises vacuum sphere and graduated tube, and vacuum sphere top has threaded hole, is connected with an end of graduated tube, and graduated tube is marked with scale, vacuum sphere with highly be higher than the liquid nitrogen container height after graduated tube is connected.
Also comprise the bayonet socket that the liquid nitrogen container bottom is provided with, said vacuum sphere bottom is provided with the buckle that matches with this bayonet socket.Be lower than requirement when graduated tube shows liquid level, and when not having liquid nitrogen to replenish this moment, can the buckle of vacuum sphere be buckled on the bayonet socket of liquid nitrogen container bottom, thereby promote the height of liquid nitrogen liquid level, cell is protected timely, also race against time for the liquid nitrogen order.
Said graduated tube top is provided with handle, can be more easily the buckle of vacuum sphere be buckled on the bayonet socket of liquid nitrogen container bottom.
Said vacuum sphere is a right cylinder, and graduated tube is vertically swum on the liquid nitrogen liquid level, is convenient to reading of data.
The utility model has designed novel liquid nitrogen height measuring device; Vacuum sphere fluctuates along with the height on liquid nitrogen surface, can be from the scale on the graduated tube that the liquid nitrogen container mouth is read with vacuum sphere links to each other, because graduated tube is beyond liquid nitrogen; Temperature influence is less; Thereby can accurately measure the position of liquid level, be immersed into which confluent monolayer cells, and in time carry out replenishing of liquid nitrogen with definite liquid nitrogen.Simultaneously, when the liquid nitrogen liquid level reduces, at the bottom of can vacuum sphere being fixed on jar, thereby the liquid level of liquid nitrogen is raise, do not have the storage thing, in time accomplish the freezing preservation of pair cell.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of liquid nitrogen container;
Fig. 2 is the structural representation of the described measurement mechanism of the utility model.
Among the figure:
1, liquid nitrogen container; 2, bayonet socket; 3, buckle; 4, vacuum sphere; 5, threaded hole; 6, graduated tube; 7, handle.
Embodiment
Shown in Fig. 1-2, show an embodiment of the measurement mechanism of liquid nitrogen height in the described a kind of liquid nitrogen container of the utility model, comprise vacuum sphere 4 and graduated tube 6; Vacuum sphere 4 tops have threaded hole 5; Be connected with an end of graduated tube 6, graduated tube 6 is marked with scale, and graduated tube 6 tops are provided with handle 7; Vacuum sphere 4 with highly be higher than liquid nitrogen container 1 height after graduated tube 6 is connected, said vacuum sphere 4 is a right cylinder.Liquid nitrogen container 1 bottom is provided with bayonet socket 2, and vacuum sphere 4 bottoms are provided with the buckle 3 that matches with this bayonet socket 2.
The utility model can be from the scale on the graduated tube that the liquid nitrogen container mouth is read with vacuum sphere links to each other, because graduated tube is beyond liquid nitrogen, temperature influence is less, thereby can accurately measure the position of liquid level.Simultaneously can be through vacuum sphere being fixed at the bottom of the liquid nitrogen container rising with quick completion liquid nitrogen liquid level.
Claims (4)
1. the measurement mechanism of liquid nitrogen height in the liquid nitrogen container comprises vacuum sphere and graduated tube, and vacuum sphere top has threaded hole, is connected with an end of graduated tube, and graduated tube is marked with scale, vacuum sphere with highly be higher than the liquid nitrogen container height after graduated tube is connected.
2. the measurement mechanism of liquid nitrogen height in a kind of liquid nitrogen container according to claim 1 is characterized in that: said vacuum sphere is a right cylinder.
