Abstract
The invention provides a pipetting gun head structure with filter elements. The pipetting gun head structure solves a problem that pollution of one pipetting gun head causes cross infection on a pipetting gun and other pipetting gun heads, and the pipetting gun head structure guarantees accuracy of experimental data. The pipetting gun head structure comprises a pipetting gun head body and is characterized in that the pipetting gun head body is close to two vertically-distributed filter elements which are installed on a connection ring face of the pipetting gun in a filled mode, the two vertically-distributed filter elements comprise an upper filter element structure and a lower filter element structure, a cavity is left between the upper filter element structure and the lower filter element structure, and the upper filter element structure and the lower filter element structure are both formed by assembling a plurality of layers of high-density glass fibers.
Description
Technical field
The present invention relates to cell and cultivate the technical field of structure, be specially the liquid transfer gun head structure with filter core.
Background technology
Liquid-transfering gun need to be changed the rifle head frequently in the process of using, in case there is a liquid transfer gun head to be pollution, will pollute liquid-transfering gun, and then cause the pollution of follow-up all liquid transfer gun heads, and this will cause cross pollution, thereby so that experimental data is inaccurate.
Summary of the invention
For the problems referred to above, the invention provides the liquid transfer gun head structure with filter core, itself so that the pollution of a liquid transfer gun head can cross infection to liquid-transfering gun, other liquid transfer gun heads, guarantee experimental data accurately.
Liquid transfer gun head with filter core, its technical scheme is such: it comprises the liquid transfer gun head body, it is characterized in that: the close connection annular plug of being connected with liquid-transfering gun of described liquid transfer gun head body is equipped with two filter cartridge constructions of arranging up and down: upper filter structure, lower filter structure, leave cavity between described upper filter structure, lower filter structure, described upper filter structure, lower filter structure are the multi-layered high-density glass fibre and combine.
After adopting said structure of the present invention, because the close connection annular plug of being connected with liquid-transfering gun of liquid transfer gun head body is equipped with two filter cartridge constructions of arranging up and down, filter cartridge construction is that the multi-layered high-density glass fibre combines, the pollutant of liquid transfer gun head inside is blocked in the filter cartridge construction, can not enter into liquid-transfering gun, itself so that the pollution of a liquid transfer gun head can cross infection to liquid-transfering gun, other liquid transfer gun heads, guarantee experimental data accurately.
Description of drawings
Fig. 1 is stereogram structural representation of the present invention.
The specific embodiment
See Fig. 1, it comprises liquid transfer gun head body 1, liquid transfer gun head body 1 close connection anchor ring 2 plugs of being connected with liquid-transfering gun are equipped with two filter cartridge constructions of arranging up and down: upper filter structure 3, lower filter structure 4, upper filter structure 4,4 on lower filter structure leave cavity 5, and upper filter structure 3, lower filter structure 4 are the multi-layered high-density glass fibre and combine.
Claims (1)
1. with the liquid transfer gun head of filter core, it comprises the liquid transfer gun head body, it is characterized in that: the close connection annular plug of being connected with liquid-transfering gun of described liquid transfer gun head body is equipped with two filter cartridge constructions of arranging up and down: upper filter structure, lower filter structure, leave cavity between described upper filter structure, lower filter structure, described upper filter structure, lower filter structure are the multi-layered high-density glass fibre and combine.
