Abstract
The utility model discloses a kind of dedicated liquid transfer gun heads of cell injuring model, including pipette tips ontology, graduation mark is provided on the lateral wall of pipette tips ontology, pipette tips ontology includes the vertical linkage section matched with liquid-transfering gun, anti-down suction is fixed in vertical linkage section, gradient section is connected with by the first arc section in vertical linkage section bottom, angle α between tilting section and horizontal plane is 15~30 °, the volume of tilting section is the 50%~80% of pipette tips body volume, tilting section is connected with dropping liquid section by the second arc section, and dropping liquid section is up big and down small conical structure.The tilting section of the utility model can avoid the outlet of pipette tips ontology and the arm of operator from backing through repeatedly above cell strain completely, prevent the liquid in liquid transfer gun head from falling into cell strain, guarantee that cell blows outstanding or cell and changes liquid quality；Anti-down suction in interconnecting piece reduces liquid in pipette tips and flows backward to the probability inside liquid-transfering gun, protects liquid-transfering gun, and then reduce economic loss.
Description
Technical field
The utility model relates to experiment equipments, more particularly, to a kind of dedicated liquid transfer gun head of cell injuring model.
Background technique
Cell injuring model is biotechnology (such as biological cloning technology) essential link.Before the study the phase by
It is more in cell culture quantity, culture amount is small, therefore while testing, usually carries out cell culture in six orifice plates, and uses in incubation
Liquid transfer gun head carries out cell strain to change liquid.Conventional liquid transfer gun head is used to have the disadvantage that firstly, liquid transfer gun head is vertical shape,
Cell strain when changing liquid in six orifice plates is in open state, and liquid-transfering gun and the arm of operator are back and forth in open cell
Pass through above culture solution and superclean bench be constantly in exhausting state at work so that the liquid in liquid-transfering gun fall in it is multiple
In different cell strains, and then there is cross-contamination phenomena, cell strain is caused to lose, causes entirely to cultivate project function when serious and lose
One basket for holding earth seriously affects experiment progress.Secondly, operator is easy to appear liquid-transfering gun maloperation situation, so that in liquid transfer gun head
Liquid suck-back enters inside liquid-transfering gun, and then corrodes liquid-transfering gun inner body, causes liquid-transfering gun to be scrapped after long-time use, increases money
Gold investment.
Summary of the invention
The utility model provides a kind of structure and is simple and convenient to operate and the dedicated liquid relief of highly-safe cell injuring model
Pipette tips.
To achieve the above object, the present invention can take following technical proposals:
The dedicated liquid transfer gun head of cell injuring model described in the utility model, including the pipette tips sheet made of transparent material
Body is provided with graduation mark on the lateral wall of the pipette tips ontology, and pipette tips ontology includes the vertical linkage section matched with liquid-transfering gun,
Be fixed with anti-down suction in the vertical linkage section, vertical linkage section bottom be connected with by the first arc section be tilted towards it is downward
The tilting section stretched, the angle α between the tilting section and horizontal plane are 15~30 °, and the volume of tilting section is pipette tips body volume
50%~80%, the dropping liquid section extended straight down is connected with by the second arc section in tilting section bottom, the dropping liquid section is
Up big and down small conical structure.
It is simple that the utility model has the advantage of structures, easy to operate, highly-safe, and it is contaminated to greatly reduce cell strain
Probability, blow the transfer of outstanding and liquid especially suitable for the cell in cell culture.This liquid transfer gun head and vertical section, tilting section and drop
Liquid section is constituted, tilting section can avoid completely pipette tips ontology outlet and operator arm above cell strain repeatedly back and forth
By preventing the liquid in liquid transfer gun head from falling into cell strain, and then reduce the contaminated probability of cell strain, it is outstanding guaranteeing that cell is blown
Or cell changes liquid quality, improves work efficiency；Anti-down suction in interconnecting piece reduces liquid in pipette tips and flows backward in liquid-transfering gun
The probability in portion protects liquid-transfering gun, and then reduces economic loss；Graduation mark on pipette tips ontology ensures accurately to measure the shifting of liquid-transfering gun
Liquid product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the dedicated liquid transfer gun head of cell injuring model described in the utility model, including be made of transparent material
Pipette tips ontology, be provided with graduation mark on the lateral wall of the pipette tips ontology, pipette tips ontology include matched with liquid-transfering gun it is perpendicular
Straight linkage section 1 is fixed with anti-down suction 2 in the vertical linkage section 1, and when flowing backwards, anti-down suction 2 absorbs the liquid of refluence
Body reduces liquid in pipette tips and flows backward to the probability inside liquid-transfering gun, protects liquid-transfering gun, and then reduce economic loss；Connecting vertically
It connects 1 bottom of section and the tilting section 4 extended obliquely downward is connected with by the first arc section 3, between the tilting section 4 and horizontal plane
Angle α is 15~30 °, and the volume of tilting section 4 is the 50%~80% of pipette tips body volume, and tilting section 4 can avoid pipette tips completely
The outlet of ontology and the arm of operator back through repeatedly above cell strain, prevent the liquid in liquid transfer gun head from falling into carefully
In born of the same parents' strain, and then the contaminated probability of cell strain is reduced, guarantees that cell blows outstanding or cell and changes liquid quality, improve work efficiency,
The dropping liquid section 6 extended straight down is connected with by the second arc section 5 in 4 bottom of tilting section, the dropping liquid section 6 is up big and down small
Conical structure.
When practical manufacture, pipette tips ontology is made of polyethylene material, it is ensured that entire liquid transfer gun head can use epoxy second
Alkane sterilizing and/or irradiation sterilization, are individually packed after sterilizing, facilitate next directly sterile use.
