Abstract
The utility model discloses a pipettor prevents suck-back device, including pipettor and pipette, its characterized in that, pipettor and pipettor end interface one end sealing connection, pipette and pipettor end interface one end sealing connection, the pipettor end interface other end is through inside hollow prevent suck-back body and pipettor end interface other end sealing connection. When using pipettor in-process operation improper, through the utility model discloses a device for excessive liquid gets into to preventing suck-back this internal, can prevent that liquid from directly sucking into the pipettor, avoids causing the harm to the pipettor.
Description
Technical Field
The utility model relates to a pipettor prevents suck-back device belongs to biological assay equipment technical field.
Background
In biological laboratories, a large number of pipettes are used. Due to factors such as insufficient operational skill and time strain, liquid is often sucked into the pipette, which not only causes contamination of the liquid, but also damages the pipette itself. Although the accidents can be relieved to a certain extent by adding cotton balls in the pipette and the gun head, the accidents cannot be completely avoided; it is therefore necessary to consider taking further measures to solve this problem.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: how to avoid liquid aspiration into the pipette.
In order to solve the technical problem, the utility model provides a pipettor prevents suck-back device is provided, including pipettor and pipette, its characterized in that, pipettor and pipettor end interface one end sealing connection, pipette and pipettor end interface one end sealing connection, the pipettor end interface other end prevents suck-back body and pipettor end interface other end sealing connection through inside hollow.
Preferably, the pipette end interface matches a port of a pipette; the pipette end interface is matched with the port of the pipette.
Preferably, the suck-back prevention body is of a hollow expanded cavity structure.
When using pipettor in-process operation improper, through the utility model discloses a device for excessive liquid gets into to preventing that suck-back is originally internal, can prevent that liquid from directly sucking into the pipettor, avoids causing the harm to the pipettor.
Drawings
Fig. 1 is a schematic plan structure view of a pipette suck back prevention device.
Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The utility model provides a pipettor prevents suck-back device, as shown in figure 1, it includes pipettor end interface 1, prevents suck-back body 2, pipettor end interface 3, pipettor 4 and pipettor 5, prevents that the both ends of suck-back body 2 are sealing connection pipettor end interface 1 and pipettor end interface 3 respectively. Pipettor 4 and 1 one end sealing connection of pipettor end interface, pipette 5 and 3 one end sealing connection of pipettor end interface, the 1 other end of pipettor end interface is through inside hollow prevent suck- back body 2 and 3 other end sealing connection of pipettor end interface.
Wherein, the pipette end interface 1 is used for connecting with a pipette; the interior of the suck-back prevention body 2 is a hollow cavity which can contain excessively sucked liquid, so that the liquid is prevented from being directly sucked into the liquid transfer device to cause damage and pollution; the pipette end interface 3 is used for connection with a pipette.
In addition, the pipette end interface 1, the suck-back prevention body 2 and the pipette end interface 3 can be of a single structure and are connected together in a sealing manner; the combined structure of the pipette end interface 1, the suck back prevention body 2 and the pipette end interface 3 can also be an integrally formed structure.
The utility model discloses a device adopts high temperature resistant plastics preparation (being adapted to later stage high temperature steam disinfection and sterilization), pipette end interface 3 according to can with the airtight design of pipette, pipette end interface 1 according to can with the airtight design of pipettor, prevent suck-back body 2 for hollow expanded cavity structures, install it between pipette and pipettor among the practical application, when the condition of taking place excessive absorption liquid, liquid can keep in the cavity in the middle, avoid directly sucking in the pipettor.
The utility model discloses a use as follows:
the pipette end interface 1 is sealingly connected to a port of a pipette, and the pipette end is sealingly connected to the pipette end interface 3, followed by extraction using a pipette. During the extraction, by preventing that suck-back body 2 cushions, prevent that the liquid of suction from getting into to the pipettor in, after the extraction, take off the liquid of collection, and right the utility model discloses a device washs, after the high-pressure disinfection, used repeatedly.
