Abstract
The utility model discloses a dynamic solution osmotic pressure detector which comprises a osmotic pressure detection pipe and a cavity body consisting of a semipermeable membrane, wherein the cavity body is provided with a standard solution; the semipermeable membrane is arranged at one end in the osmotic pressure detection pipe; a spring is arranged at the other end in the osmotic pressure detection pipe; a pressing sheet is arranged at the outer end of the spring to extrude the cavity body consisting of the semipermeable membrane; a liquid inlet is formed in one end, provided with the semipermeable membrane, of the osmotic pressure detection pipe; a vent hole is formed in the other end of the osmotic pressure detection pipe. The osmotic pressure detector is simple in structure, low in manufacturing cost and capable of conveniently and quickly performing an osmotic pressure detection experiment and accurately reading out data according to a scaleplate.
Description
Technical field
The utility model relates to laboratory apparatus, relates in particular to a kind of osmotic pressure detecting instrument.
Background technology
Osmotic pressure detects as normal experiment, but while testing at present, mostly utilizes the equipment such as existing test tube, combination is installed voluntarily and tests, and unavoidably affects experiment effect, has also increased cut-and-try work amount.
In addition, cell cultures needs certain osmotic pressure to maintain the physiology and morphology activity of cell, in experimentation, often because of dosing, evaporation etc., changed the osmotic pressure of solution, can cause testing inaccurate, even necrocytosis, conventional detection is to be sampled in instrument to detect, can not dynamic monitoring.
Utility model content
Technical problem to be solved in the utility model is to realize a kind of simple in structurely, is provided with osmotic pressure detecting instrument easily.
To achieve these goals, the technical solution adopted in the utility model is: dynamic solution osmotic pressure detector, comprise osmotic pressure detector tube and the cavity being formed by semi-permeable membranes, described cavity is provided with standardized solution, and described semi-permeable membranes is placed in one end in osmotic pressure detector tube, and the other end is provided with spring, described spring outer end is provided with compressing tablet, the cavity that described compressing tablet extruding semi-permeable membranes forms, one end that described osmotic pressure detector tube is provided with semi-permeable membranes is provided with inlet opening, and the other end is provided with ventilating pit.
Described osmotic pressure detector tube is provided with scale.
Described osmotic pressure detector tube is sealed at both ends cylindrical tube.
The utility model osmotic pressure detector can be used for laboratory solution preparation, tests the dynamic monitoring of culture solution while carrying out such as cell cultures, and simple in structure, low cost of manufacture, can conveniently carry out osmotic pressure test experience, and can be accurately according to scale sense data.
Accompanying drawing explanation
Below the content of every width accompanying drawing expression in the utility model specification sheets and the mark in figure are briefly described:
Fig. 1 is dynamic solution osmotic pressure detector arrangement schematic diagram;
Mark in above-mentioned figure is: 1, spring; 2, osmotic pressure detector tube; 3, compressing tablet; 4, semi-permeable membranes; 5, ventilating pit; 6, inlet opening; 7, standardized solution; 8, scale.
Embodiment
Known referring to Fig. 1, dynamically solution osmotic pressure detector comprises osmotic pressure detector tube 2 and the cavity consisting of semi-permeable membranes 4, wherein osmotic pressure detector tube 2 is sealed at both ends cylindrical tube, one end is provided with ventilating pit 5, the other end is provided with inlet opening 6, in the cavity being formed by semi-permeable membranes 4, be filled with for measuring the standardized solution 7 of osmotic pressure, it is placed in the inner one end of osmotic pressure detector tube 2, osmotic pressure detector tube 2 the other ends are provided with the spring 1 extending internally, the end of this spring 1 is fixed with compressing tablet 3, compressing tablet 3 sizes are slightly less than osmotic pressure detector tube 2 interior dimensionss, the cavity that these compressing tablet 3 extruding semi-permeable membraness 4 form.One end that osmotic pressure detector tube 2 is provided with semi-permeable membranes 4 is inlet opening 6, and the other end is ventilating pit 5, and inlet opening 6 and ventilating pit 5 are uniformly distributed.
Osmotic pressure detector tube 2 is provided with scale 8, while not using, compressing tablet 3 is being pressed the cavity consisting of semi-permeable membranes 4, it is positioned at scale 8 zero graduation positions, put into and measure after solution, compressing tablet 3 can be suffered oppression and be changed position along with semi-permeable membranes 4 expansions, and its indicated scale is measured solution osmotic pressure, thereby can measure dynamically, fast whether standard of osmotic pressure.This dynamic solution osmotic pressure detector is the disposable equipment that is provided with.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
