Abstract

The utility model discloses a sodium hydroxide solution storage device, which relates to the technical field of chemical solution storage containers. The upper part of the storage bottle is provided with a silica gel plug, and the bottom of the drying tube is inserted in the silica gel plug to communicate with the storage bottle. The bottom is provided with a rubber stopper, and the conduit is inserted into the rubber stopper to communicate with the storage bottle, and a stop valve is installed on the conduit. It can overcome the disadvantages of the existing technology, and the structural design is reasonable and novel. A rubber plug is directly installed at the bottom of the storage bottle to connect with the catheter. When in use, a sample cup is placed at the outlet of the catheter, and the stop valve is opened to store the sodium hydroxide solution in the bottle. It just needs to flow into the sample cup, which reduces the frequency of contact between the original solution of sodium hydroxide solution and air, reduces the preparation time of the laboratory technician, and reduces the workload of the laboratory technician, and this sodium hydroxide solution storage device is simple and convenient to operate , suitable for promotional use.

Description

A kind of sodium hydroxide solution storage device

technical field

The utility model relates to a sodium hydroxide solution storage device, which belongs to the technical field of biochemical solution storage containers.

Background technique

Sodium hydroxide solution storage device is that sodium hydroxide is mixed with the necessary dress container of sodium hydroxide solution, and existing sodium hydroxide solution storage device is a sealed plastic bottle, (as shown in Figure 1) when taking sodium hydroxide When using the solution, it is necessary to open the lid of the plastic bottle and pour out the sodium hydroxide solution, which will cause the original solution of the sodium hydroxide solution to contact with the air, resulting in the impurity of the sodium hydroxide solution. The current solution is to add a small amount of sodium hydroxide solution, which not only increases the workload of the laboratory technician, but also increases the sample inspection time. Therefore be badly in need of developing a kind of novel sodium hydroxide solution storage device.

Contents of the invention

In view of the above problems, the technical problem to be solved by the utility model is to provide a sodium hydroxide solution storage device.

The sodium hydroxide solution storage device of the present utility model comprises a storage bottle, a silica gel plug, a drying tube, a rubber plug, a catheter and a flow stop valve. The upper part of the storage bottle is provided with a silica gel plug, and the bottom of the drying tube is inserted into the silica gel plug and The storage bottle is connected, and the bottom of the storage bottle is provided with a rubber stopper, and the conduit is inserted into the rubber stopper to communicate with the storage bottle, and a stop valve is installed on the conduit.

Beneficial effects of the utility model: it can overcome the drawbacks of the prior art, the structural design is reasonable and novel, a rubber plug is directly installed at the bottom of the storage bottle to connect with the catheter, and a sample cup is placed at the outlet of the catheter when in use, and the stop valve is opened to store The sodium hydroxide solution in the bottle can flow into the sample cup, which reduces the frequency of contact between the original solution of sodium hydroxide solution and air, reduces the preparation time of the laboratory technician, and reduces the workload of the laboratory personnel. The storage device is simple and convenient to operate, and is suitable for popularization and use.
