Description
Technical field
The present invention relates to a kind of pipette, more particularly to a kind of serum pipette.
Background technology
Pipette is the measuring device for accurately pipetting the solution of certain volume, and pipette is that one kind measures formula instrument, is used for
The volume that it releases solution is measured, its lower end is sharp mouth shape, and different scales is carved with body, is to pipette the accurate body of liquid
Long-pending mark, scale can be accurate to 0.01mL.Point taking bulk solutions to be in basic biology and medical experiment at present must not
The operation that can lack, is generally all drawn with pipette, and pipette has the advantages of accuracy is high, so pipette is normal
As a kind of common instrument of transfer liquid., often will be a certain amount of big using pipette in chemistry, biology, medical industries field
The liquid of volume is transferred to from a container in another container.Pipette often coordinates ear washing bulb to be used together, and utilizes ear washing bulb
The mode of air-breathing carries out the transfer work of liquid.Serum needs as material most indispensable in cell culture in cell culture
Individually to add, and often addition in cell culture medium, mixes latter with cell culture medium and is used for cell culture.At present, it is existing
There is the pipette in technology there are the different sizes such as 1mL, 2mL, 5mL, 10mL, 25mL and 50mL, also there is straight trip pipe and fat tripe pipe
Two types.
But there is following defect in existing pipette：
Acid treatment, then repeatedly cleaning rinse must be steeped during use, high pressure steam sterilization use is then carried out again, so as to cause
Many unnecessary resource costs, and needed during liquid relief it is with finger that the top of pipette is clogging, it is not only dangerous but also make
Into experimental error.
