Say, serve very big substantial role, be worthy to be popularized.
For achieving the above object, this utility model provides following technical scheme：A kind of quantitative pipet, including suction inlet, pipe
Body, air bag and connecting rod, also include heat-insulation layer and panel, and described heat-insulation layer is arranged on panel inside and panel and insulation
It is provided with connecting hole between layer, be connected with adjustment block above described body, described adjustment block both sides are provided with pore, described pore
Diameter is less than adjustment block width, and described adjustment block is arranged in connecting rod, and described connecting rod is additionally provided with dialing knob, described
Air bag is connected with connecting rod, and described panel is arranged on bottom of the pipe, and described inboard wall of tube body is connected with display, described control
Plate is connected with piston by action bars, and described piston is arranged in pipet, is provided with clear between described pipet and panel
Washing liquid, also includes suction ball in described pipet, described suction ball is connected with piston and for being distributed up and down, below described pipet
It is provided with suction inlet, described suction inlet diameter is less than inhales bulb diameter.
As a kind of preferred technical scheme of this utility model, described display passes through quantifier and the company within panel
Connect hole contact.
As a kind of preferred technical scheme of this utility model, leave between described heat-insulation layer and panel certain interval and
Both are rectangle.
As a kind of preferred technical scheme of this utility model, rubber sleeve is set outside described body.
As a kind of preferred technical scheme of this utility model, described dialing knob is connected with adjustment block.
Compared with prior art, the beneficial effects of the utility model are：
This utility model carries out measure control by dialing knob to liquid, then draws and adjusted using adjustment block during liquid
Whole, just can realize the process control to liquid relief, be further ensured that the quantitation of pipetting processes, when people as needed, adjust
Dialing knob, pins air bag, and pore discharges gas, and by suction inlet alignment liquid, piston is risen by panel by control operation bar, inhales
Ball just carries out quantitative absorption from suction inlet to liquid, and heat-insulation layer is incubated to liquid, and quantifier shows to liquid measure, display
Go out liquid meter, if the metering required for not reaching, at this time, adjustment block just can play a role, revolved according to scale
Button controls to inhaling ball, accurate further to liquid meter, requires until meeting, and display shows required metering, during use
Rubber sleeve protects the control to body for the user, and pipetting processes are more stable, and connecting hole accurately measures liquid meter for quantifier
There is provided and ensure, after holding liquid, piston can be put down by action bars, fix liquid and do not leak, and operate again and just can realize
Pipetting processes, after the completion of, by cleanout fluid, pipet can be carried out, practical, it is worthy to be popularized.
