Chuck upper center through-hole connects piston, and the upper cover of piston rod is equipped with spring, is installed between the pressure cap and dropper chuck
There is spring.
As further program of the utility model：It is connected with squeezing handle on the dropper jackets outer wall.
As further program of the utility model：The piston is slidably mounted in the imbibition chamber inside glass dropper.
As further program of the utility model：The spring top is fixed on pressure cap inner wall, and spring bottom end is solid
It is scheduled on the outer wall of dropper chuck top.
As further program of the utility model：The glass dropper outer wall is equipped with graduation mark.
As further program of the utility model：The piston uses cast-iron piston, steel pistons or all-aluminium piston.
Compared with prior art, the utility model has the beneficial effects that：A kind of natural sciences experiment piston type dropper, knot
Structure is simple, easy to operate, substitutes original trickle irrigation rubber head by pressure cap and piston, index finger and middle finger are clipped in the drop below squeezing handle
Pipe clamp is put on, and thumb press is on pressure cap, thumb press pressure cap, and piston rod pushes piston along imbibition chamber slide downward, bullet
Spring is compressed, and then glass dropper bottom end suction nozzle is inserted into reagent to be inhaled, and unclamps thumb on pressure cap, is made in spring force
Under, pressure cap, piston rod and piston upward sliding, imbibition chamber is interior to suck reagent in negative pressure, and pressing pressure cap drips reagent
Go out, it is easy to operate, it is time saving and energy saving, when glass dropper topples over placement, avoid reagent from one section of spilling of pressure cap, it will not be to passing
The Capsule of system causes to corrode.
