Description
Technical field
The invention belongs to experiment equipment technical fields, and in particular to a kind of novel all-in-one sample diluting device.
Background technology
It is frequently necessary to be diluted sample in biology, chemical experiment in the prior art, is usually to use in the prior art
Pipettor first measures diluent, then measures sample again, and sample is added in diluent, draws dilution again after mixing,
Separate operations, it is cumbersome, and experiment consumptive material is wasted, if it is possible to provide a kind of by measurement sample, measurement dilution
Agent mixes these steps and concentrates in a pipettor operation and will greatly reduce experimental cost, improves conventional efficient.
Invention content
Technical problem:Novel all-in-one sample diluting device.
Technical solution:A kind of novel all-in-one sample diluting device, including air bag, capillary, protection sleeve pipe, the capillary
One end be sealed end, the other end of the capillary is open end, and the sealed end of the capillary is inserted into air bag, the hair
The open end of tubule is inserted into protection sleeve pipe, and the capillary midsection is equipped with micropore and easily-folding line, and the easily-folding line is close to capillary
The sealed end of pipe, the micropore is close to the open end of capillary.
Preferably, the internal diameter of the capillary is 0.5~2.0mm.
Preferably, the open end of the micropore and capillary distance is 5~30mm.
Preferably, the sealed end of the easily-folding line and capillary distance is 5~25mm.
Preferably, the capillary easily-folding line is located at the inside of air bag, and with air bag lower part on a horizontal plane.
Preferably, being equipped with diluent in the air bag.
Downward, there is one end of protection sleeve pipe in one end that diluter is first had air bag by the present invention when in use upward, by capillary
Pipe fractures along easily-folding line, pulls up protective case, horizontally or diagonally under state, by the opening end in contact of capillary liquid to be inhaled, sample
This is inhaled into capillary through capillary action, after sample liquid level reaches micropore and closed porosity, draws and stops, and then will
Diluter has one end of air bag upward, at this point, the diluent in air bag all focuses on the bottom of air bag, squeezes air bag, air bag
In diluent and sample be all discharged by capillary, can by air bag diluent and sample squeeze into protective case,
Then mixing obtains dilution, then capillary is placed under the liquid level of dilution, squeezes air bag, can draw and all dilute
Liquid.
Advantageous effect:
The invention discloses a kind of novel all-in-one sample diluting devices, using the pipettor mixing sample in a pipette
In can operate, it is easy to use, improve conventional efficient.
Figure of description
