Abstract
What is disclosed in the present invention is to provide a quantitative transfer pipette structure, wherein an anti-backflow compartment is configured in the first bulb. The dimensions and locations of the first bulb, the second bulb and the third bulb are specifically configured to aspirate and transfer a specific volume of the liquid to a container, mix the liquid with the substance in the container by pressing and releasing the specific bulbs, so as to achieve the effects of precise quantification and sufficient mixing.
Claims10
A quantitative transfer pipette structure, comprising:
- a hollow tubular body containing an opening and a top opening;
- a first bulb containing an anti-backflow compartment having an upper edge being equal to or lower than the position of the top opening in height, wherein the first bulb is situated at one of the conditions (a) and (b) as follows:
- (a) the first bulb interconnects with the top opening via a first channel, and
- (b) the first bulb encloses the top opening;
- a second bulb configured to interconnect with the first bulb via one of the conditions (c) and (d) as follows:
- (c) a second channel, and
- (d) the second channel and the first channel sequentially;
- and
- a third bulb configured to interconnect with the first bulb via one of the conditions (e), (f), (g) and (h) as follows:
- (e) a third channel, the second bulb and the second channel sequentially;
- (f) the third channel and the second channel sequentially;
- (g) the third channel;
- and
- (h) the third channel and the first channel sequentially;
- wherein a capacity of the first bulb is equal to or larger than that of the hollow tubular body, a capacity of the second bulb is smaller than that of the hollow tubular body, and a capacity of the third bulb is equal to or larger than that of the hollow tubular body.
