Description
Technical field
The utility model relates to laboratory apparatus, is specifically related to a kind of experiment liquid getting device being applicable to strong acid-base, corrosive solution.
Background technology
In organic chemistry student experimenting; often can use concentrated acid, concentrated alkali solution and there is strong impulse smell and strongly corrosion liquid in a large number; these liquid are extremely dangerous in suction process; be easy to meet accident; especially when student is also unfamiliar with the correct acquisition mode of dangerous solution; frequent meeting is burnt, scald or can, by the strong stimulation smell impairment of solution, cause student to produce this class I liquid I frightened.This class I liquid I was in the process obtained in the past, and only with glass pipette or glass pipet, but these two kinds of utensils are very easily damaged, can cause liquid drip leakage, shed initiation secondary injury.
Summary of the invention
The purpose of this utility model is overcome the deficiencies in the prior art and provide one to be applicable to strong acid-base, corrosive solution, and security is high, the experiment liquid getting device of conveniently taking.
The technical solution of the utility model is achieved in that
A kind of experiment liquid getting device, comprise the supervisor that end is provided with suction pipe, supervisor top is provided with lid, lid leaves centre bore, piston is provided with in supervisor, upper piston area is provided with push rod, push rod is through the centre bore of supervisor's lid, upper piston area is also provided with spring, spring housing is contained on push rod, and the bottom of spring is arranged on piston or is arranged on the bottom of push rod, and the top of spring is arranged on the lid of supervisor, piston lower portion is provided with rubber washer, and the outer wall of described supervisor is provided with longitudinal rule.
Described push rod top is provided with and pushes away handle.
The top outer wall of described supervisor is provided with handle.
Described rule is provided with navigation button, and navigation button card on the scale and slide along rule.
Good effect of the present utility model: structure is simple, easy to operate, only when taking or discharge solution, slightly firmly need press push rod, getting final product complete operation; The phenomenon such as can not produce water clock, shed, durable, degree of safety is very high.
Accompanying drawing explanation
Fig. 1 is agent structure schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of experiment liquid getting device, comprise the supervisor 3 that end is provided with suction pipe 6, the top outer wall of supervisor 3 is provided with handle 7, convenient by holding liquid getting device, be responsible for 3 tops and be provided with lid, lid leaves centre bore, piston 4 is provided with in supervisor 3, piston 4 top is connected with push rod 2, push rod 2 is through the centre bore of supervisor 3 lid, push rod 2 top is provided with and pushes away handle 1, piston 4 top is also connected with spring 8, spring 8 is sleeved on push rod 2, the bottom of spring 8 is fixed on piston 4 or is fixed on the bottom of push rod 2, the top of spring 8 is connected on the lid of supervisor 3, piston 4 bottom is attached to double-layer rubber packing ring 5, described rubber washer 5 strong acid-base resistance, corrosion-resistant, and with supervisor 3 inwall tight connecting, ensure that the sealing in supervisor, the outer wall of supervisor 3 is provided with longitudinal rule 10, rule 10 is provided with navigation button 9, navigation button 9 to be stuck on rule 10 and to slide along rule 10.
When taking solution, pressing downwards pushes away handle, and extrude the air in supervisor, sunk to by suction pipe in solution, unclamp and push away handle, piston bounces back under the pulling force of spring, then inhalation solution, can read the amount of inhaled solution according to rule; During release solution, pressing pushes away handle, and piston moves down then extrusion solution, can improve the processing safety in experiment like this, complete experimental implementation quickly and efficiently, the phenomenon such as can not produce water clock, shed, and efficiently avoid the generation of experiment accident.
Claims (4)
