Description
Technical field
The utility model relates to experiment apparatus technical field, is specifically related to a kind of Anti-contamination pipette tip.
Background technology
Liquid-transfering gun is the one of pipettor, and be usually used in pipetting of a small amount of or micro liquid in laboratory, the liquid-transfering gun of different size supports the use corresponding liquid transfer gun head and uses.
Existing liquid transfer gun head also exists following problem:
(1), weeping or liquid transfer gun head may be there is after imbitition from obscission liquid-transfering gun in the inner wall smooth of liquid transfer gun head, and frictional force between liquid-transfering gun is little, causes the sealing between liquid-transfering gun and liquid transfer gun head poor.
(2) (1000uL liquid is drawn as used the liquid-transfering gun of 1000uL) when operator's liquid draw scale of construction reaches maximum, often need to make the position remained on lower than test tube, the position of liquid-transfering gun could draw the liquid of q.s, now liquid just likely flow to the joining place of liquid-transfering gun and liquid transfer gun head, and this joining place is the position of non-sterile process or has been infected with other liquid, therefore liquid very likely can be contaminated, thus affect experimental result.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of Anti-contamination pipette tip, can strengthen the sealing and stability that are connected between liquid-transfering gun with liquid transfer gun head, and can prevent liquid contamination.
For achieving the above object, the utility model provides following technical scheme:
Anti-contamination pipette tip of the present utility model, comprise rifle head body and anti-pollution seal sleeve, described rifle head body comprises imbibition section, liquid storage section and liquid-transfering gun interface section from bottom to up successively, to be placed in described anti-pollution seal sleeve in liquid-transfering gun interface section and with liquid-transfering gun interface section interference fit, described anti-pollution seal sleeve is provided with the infundibulate water conservancy diversion plug be connected as a single entity with anti-pollution seal sleeve in the port of liquid storage section, described infundibulate water conservancy diversion plug uncovered towards liquid storage section, thin mouth is towards liquid-transfering gun interface section.
Further, the thin mouth diameter of described infundibulate water conservancy diversion plug is 1/3 ~ 1/6 of uncovered diameter.
Further, described anti-pollution seal sleeve forms near the outside bending of port of liquid-transfering gun interface section the sealing ring wrapping up liquid-transfering gun interface section port.
Further, described liquid-transfering gun interface section inwall is provided with annular boss I, and described anti-pollution seal sleeve outer wall is provided with the annular boss II matched with annular boss I.
Further, the diameter of described liquid storage section is greater than the diameter of imbibition section and liquid-transfering gun interface section.
Further, the material of described rifle head body is plastics or glass, and the material of described anti-pollution seal sleeve is elastic caoutchouc.
The beneficial effects of the utility model are:
The utility model is provided with anti-pollution seal sleeve in the liquid-transfering gun interface section of rifle head body, be connected by anti-pollution seal sleeve between liquid-transfering gun with liquid transfer gun head, enhance sealing and the stability of connection, and be also provided with infundibulate water conservancy diversion plug in the port of anti-pollution seal sleeve, infundibulate water conservancy diversion plug neither affects carrying out smoothly of imbibition operation, can prevent again liquid runs down liquid transfer gun head inwall from blowing back into the joining place of liquid transfer gun head and liquid-transfering gun, thus can prevent liquid contamination.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the A place enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of the utility model embodiment 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Embodiment 1
Fig. 1 is the structural representation of the utility model embodiment 1, Fig. 2 is the A place enlarged drawing of Fig. 1, as shown in the figure, the Anti-contamination pipette tip of the present embodiment comprises rifle head body 1 and anti-pollution seal sleeve 2, described rifle head body 1 comprises imbibition section 11 from bottom to up successively, liquid storage section 12 and liquid-transfering gun interface section 13, to be placed in described anti-pollution seal sleeve 2 in liquid-transfering gun interface section 13 and with liquid-transfering gun interface section 13 interference fit, described anti-pollution seal sleeve 2 is provided with the infundibulate water conservancy diversion plug 3 be connected as a single entity with anti-pollution seal sleeve 2 in the port of liquid storage section 12, described infundibulate water conservancy diversion plug 3 uncovered towards liquid storage section 12, thin mouth is towards liquid-transfering gun interface section 13, be connected by anti-pollution seal sleeve 2 between liquid-transfering gun with liquid transfer gun head, enhance sealing and the stability of connection, and infundibulate water conservancy diversion plug 3 can prevent liquid runs down liquid transfer gun head inwall from blowing back into the joining place of liquid transfer gun head and liquid-transfering gun, can prevent liquid contamination.
