Abstract
The utility model discloses a volumetric flask for chemical experiments, belonging to the technical field of instruments for the chemical experiments. The volumetric flask comprises a bottle and a bottle cork, wherein the bottle comprises a bottle body and a bottle neck, the bottle cork is ground and sealed at a bottle mouth at the neck part of the bottle neck, a ferrule is arranged on the outer wall at the upper end of the bottle neck, a connecting band is connected on the ferrule, and the other end of the connecting band is fixedly connected with the center at the top of the bottle cork; an anti-skid device is arranged at the part which is close to the bottle mouth on the bottle neck; and the anti-skid device is an anti-skid sleeve fixed on the outer wall at the upper part of the bottle neck or a conical clip hand ring arranged on the outer wall at the upper end of the bottle neck. The volumetric flask disclosed by the utility model has the following advantages that 1) the bottle cork is connected with the ferrule at the mouth of the bottle neck through the connecting band, so that the bottle cork can be prevented from falling or being lost during the experimental process; and 2) the anti-skid device is arranged on the bottle neck, so that the volumetric flask can be prevented from slipping off the hand of an experimenter.
Description
Technical field
The utility model relates to chemical experimental instrument, specifically, relates to a kind of chemical experiment volumetric flask.
Background technology
Volumetric flask is the bottle end vial of a kind of elongated necks with ground glass stopper, pyriform, is accurate laboratory apparatus commonly used in the chemical experiment, and it mainly is made of bottle and bottle stopper, and bottle comprises body and bottleneck, and the bottle stopper ground is sealed in the bottle mouth position at bottleneck top.The defective that existing volumetric flask exists is: 1, bottle stopper and bottle are disconnected from each other, and in the experimentation, bottle stopper is easy to fall or lose from experimental bench; When 2, testing, hand will be held bottleneck, and bottleneck is very smooth, and volumetric flask is easy to slippage from experimenter's hand.
The utility model content
The technical problems to be solved in the utility model provides a kind ofly to be avoided bottle stopper to fall or loses, and can prevent the chemical experiment volumetric flask of slippage from hand.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of chemical experiment volumetric flask comprises bottle and bottle stopper, and bottle comprises body and bottleneck, the bottle stopper ground is sealed in the bottle mouth position at bottleneck top, be provided with lasso on the upper end outer wall of described bottleneck, be connected with connecting band on the lasso, the other end of connecting band is fixedly connected with the top center of bottle stopper; Position near bottleneck on the described bottleneck is provided with shoe; It is characterized in that: described shoe is to be fixed on the Anti-slip cover on the bottleneck external wall of upper portion or to be arranged on conic clamp bracelet on the outer wall of bottleneck upper end.
Owing to adopted technique scheme, compared with prior art, the utlity model has following advantage: 1, bottle stopper is connected by the lasso of connecting band with the bottle neck place, can avoid that bottle stopper falls or loses in the experimentation; 2, bottleneck is provided with shoe, can prevent volumetric flask slippage from experimenter's hand.
