Abstract
The utility model relates to a kind of pipettor core filter core, comprises chimney filter, pipettor bayonet socket cover, suction nozzle bayonet socket cover and sealing ring.Described chimney filter is between described pipettor bayonet socket cover lower end and described suction nozzle bayonet socket set upper side, and described pipettor bayonet socket cover, described chimney filter and described suction nozzle bayonet socket cover are tightly connected by described sealing ring.With core in described chimney filter, the inner headed face of described core and described chimney filter is tightly connected.The advantage of this practicality invention is: solve pipettor inner chamber easily by sample cross contamination etching problem; simultaneously; this device uses extremely easy; even also replacement can be dismantled quickly and easily in the contaminated situation of filter core; not only protect pipettor but also common suction nozzle can be used, not only economy but also practical.
Description
Technical field
The utility model relates to biology, chemistry and medicine and other fields, particularly a kind of pipettor core filter core.
Background technology
Pipettor is the common tool quantitatively drawing various liquid, in use there will be the contaminated situation of its inner chamber unavoidably, the material that microorganism, dust, volatile ingredient and suck-back enter pipettor not only can cause the cross pollution of sample room, also can corrode pipettor.
At present, the method solving this problem has the suction nozzle used with filter core, or adopts the pipettor of built-in filter core.The former belongs to the improvement carried out on experiment consumptive material, because suction nozzle is disposable product, consumption is large, and cost is higher; The latter belongs to and improves in pipettor internal structure, and its marketing amount is little, and still cannot solve the easy contaminated problem of built-in filter core.
Therefore, one can either prevent pipettor inner chamber contaminated, can Fast Installation can overcome the above problems with the servicing unit not increasing again consumptive material use cost while of dismounting.
Summary of the invention
For above-mentioned existing problems; the utility model provides a kind of pipettor core filter core; device between pipettor and suction nozzle can be sealedly connected on by designing one with filter membrane; solve pipettor inner chamber easily by problem that sample cross contamination corrodes; meanwhile, this device uses extremely easy, even also can dismantle replacement quickly and easily in the contaminated situation of filter core; not only protect pipettor but also common suction nozzle can be used, economical and practical.
For reaching above object, the utility model takes following technical scheme, a kind of pipettor core filter core, comprises chimney filter, pipettor bayonet socket cover, suction nozzle bayonet socket cover and sealing ring.Described chimney filter is made up of core and chimney filter cover, and described chimney filter is between described pipettor bayonet socket cover lower end and described suction nozzle bayonet socket set upper side, and described pipettor bayonet socket cover, described chimney filter and described suction nozzle bayonet socket cover are tightly connected by described sealing ring.With core in described chimney filter cover, the inner headed face that described core and described chimney filter overlap is tightly connected.
Further, described pipettor bayonet socket cover internal diameter equals pipettor sleeve outer diameter, and described suction nozzle bayonet socket cover external diameter equals suction nozzle internal diameter.
Further, described core is flat cylindric, and thickness is 1 ~ 3mm.
When using this pipettor with core filter core, pipettor bayonet socket cover being enclosed within pipettor sleeve, then suction nozzle being enclosed within suction nozzle bayonet socket and putting, then use by the normal using method of common pipettor.
The beneficial effects of the utility model are:
Device between pipettor and suction nozzle can be sealedly connected on by designing one with filter membrane; solve pipettor inner chamber easily by problem that sample cross contamination corrodes; simultaneously; this device uses extremely easy; even also replacement can be dismantled quickly and easily in the contaminated situation of filter core; not only protect pipettor but also common suction nozzle can be used, economical and practical.
Filter core of the present utility model is core, because it is rigid material, compares have good permeability with common filter paper with filter membrane, not yielding, difficult drop-off, the advantage that can reuse.
Specification of the present utility model can be adaptive separately according to the pipettor of different size, can change efficiently, and can reuse after ultrasonic cleaning.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model
1 is pipettor bayonet socket cover, and 2 is suction nozzle bayonet socket covers, and 3 is sealing rings, and 4 is chimney filters, and 41 is chimney filter covers, and 42 is cores.
Detailed description of the invention
The utility model provides a kind of pipettor core filter core, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes below to the utility model.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1:
A kind of pipettor core filter core, comprises chimney filter 4, pipettor bayonet socket cover 1, suction nozzle bayonet socket cover 2 and sealing ring 3.Chimney filter 4 overlaps 1 lower end and suction nozzle bayonet socket overlaps between 2 upper ends at pipettor bayonet socket, and described chimney filter 4 overlaps 41 by core 42 and chimney filter and forms, and pipettor bayonet socket cover 1, chimney filter 4 and suction nozzle bayonet socket cover 2 are tightly connected by sealing ring 3.With core 42 in chimney filter cover 41, the inner headed face that core 42 and described chimney filter overlap 41 is tightly connected.Pipettor bayonet socket overlaps 1 internal diameter and equals pipettor sleeve outer diameter, and suction nozzle bayonet socket overlaps 2 external diameters and equals suction nozzle internal diameter, and core 42 is flat cylindric, and thickness is 2mm.
When using this pipettor with core filter core, pipettor bayonet socket cover 1 being enclosed within pipettor sleeve, then suction nozzle being enclosed within suction nozzle bayonet socket cover 2, then using by the normal using method of common pipettor.
Below the utility model is described in detail, the above, be only the preferred embodiment of the utility model, when not limiting the utility model practical range, namely allly do impartial change according to the application's scope and modify, all should still belong in the utility model covering scope.
