Abstract
The utility model discloses a glass apparatus, in particular a universal burette for acid and base, which comprises a tube body, a control part and a sharp glass nozzle. The universal burette for acid and base is characterized in that the control part is a silicone tube with resistance against acid and base, a glass ball is arranged in the silicone tube, the top end of the tube body is provided with a funnel-shaped inlet, and an elastic sheath is sleeved outside the sharp glass nozzle. The utility model has the advantages of simple structure and low manufacturing cost, the control part adopts the silicone tube and can be generally used for acid and base, the funnel-shaped inlet on the top end of the tube body can prevent the liquid from leaking, and the elastic sheath on the bottom end of the tube body can prevent the sharp glass nozzle from being broken, thereby facilitating the use and protection.
Description
(1) technical field
The utility model relates to a kind of glass apparatus, the general buret of particularly a kind of soda acid.
(2) background technology
Buret is widely used in the physico-chemical analysis of industries such as chemical industry, medicine at present, existing buret is divided into two kinds of acid buret and base burets, two kinds of burets can not be general mutually, control section leaks acid easily or leaks alkali, the top of buret is that straight tube shape liquid spills easily when pouring liquid, the glass of buret bottom point mouth is easy to fragmentation simultaneously, is not easy to protection, and causes waste.
(3) summary of the invention
The utility model provides a kind of leakage, general buret of the soda acid of being convenient to protect of preventing in order to remedy the defective of prior art.
The utility model is achieved by the following technical solution:
The general buret of a kind of soda acid comprises the body, control section and the glass point mouth that are connected, and it is characterized in that: control section is the silicone tube of acid and alkali-resistance, and silicone tube is built-in with a glass marble.
The general buret of this soda acid, the body top is provided with falred entrance, and liquid is not easy to spill during pouring liquid; The flexible sheath of glass point mouth overcoat can prevent effectively that glass point mouth from being collided the back fragmentation.
The beneficial effects of the utility model are: the general buret of this soda acid, simple in structure, low cost of manufacture, control section adopts silicone tube can realize that soda acid is general, the falred entrance on body top can prevent that liquid from spilling, the flexible sheath of body bottom can prevent the fragmentation of glass point mouth, and is easy to use, is convenient to protection.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the structural representation of the general buret of the utility model soda acid.
Among the figure, 1 body, 2 falred entrances, 3 silicone tubes, 4 glass marbles, 5 glass point mouth, 6 flexible sheaths.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.The general buret of this soda acid, comprise the body 1, control section and the glass point mouth 5 that are connected, it is characterized in that: control section is the silicone tube 3 of acid and alkali-resistance, and silicone tube 3 is built-in with a glass marble 4, body 1 top is provided with falred entrance 2, the flexible sheath 6 of glass point mouth 5 overcoats.
The general buret of this soda acid uses reagent bottle to aim at falred entrance 2 pouring liquids, is not easy to spill, and silicone tube 3 has the effect of acid and alkali-resistance, can control liquid by glass marble 4 and flow out, and flexible sheath 6 has anticollision, breakage-proof effect.
Claims (3)
1. the general buret of soda acid comprises the body (1), control section and the glass point mouth (5) that are connected, and it is characterized in that: control section is the silicone tube (3) of acid and alkali-resistance, and silicone tube (3) is built-in with a glass marble (4).
2. the general buret of soda acid according to claim 1 is characterized in that: body (1) top is provided with falred entrance (2).
3. the general buret of soda acid according to claim 1 is characterized in that: the glass point flexible sheath of mouth (5) overcoat (6).
