Used for storing acids and alkaline solutions

Since it is a type without a stopper, its hands do not get dirty when opened and it is very good. Even without a stopcock, there is no concern about sealability. I think that many bottles of this type are valuable items as they are of the inner plug type.
For storage of detergent

It was used for storing small amounts of detergent at the site, but it is good to be light. However, it is a bit weak. I have a cowardly worker, but I grasp it and I am transforming it. Well ~ Even if it transforms, it returns to the original, so there is no big problem, but half things say that it is hard to hold and easy to grasp.

It is convenient to use for repeated cultivation of orchids, and I like the economically advantageous products very much.

Light, leaky, good.
Better if the memory is black.
It is used when shipping paint in small portions.

Compared with putting other manufacturer's goods and paint and comparing it, changed paint to this article because paint was hard to spill.

There is no liquid leakage. It is the most wonderful of the containers I have used.
I want a wider opening.
It is used for sample subdivision.

I was saved because I could purchase it at roses. I will use it in the demonstration experiment of the student. It is easy to open the lid, it is easy to use because it will be chitin.
Collection and storage of water samples

The price is cheap for a chemistry laboratory who has a relationship, but I use it because the delivery date is early.
It is very good without leaking.
Separate powder and liquid in small portions

I bought 3 items of 50ml, 250ml, 500ml.
For storage of fine powder, such as powder with, easy to put, easy to take out is very convenient. Also, if you want to put the desiccant together, you can also choose a larger one because it is a wide mouth.
Liquid is also suitable for storage without leaking.
If you use it by sucking up with a pipette or syringe, because there is no inner lid, it is convenient to work quickly.
Because it is made of PP, it is strong against various organic solvents, but if it is a liquid with a boiling point of about 40 degrees such as dichloromethane, the contents gradually decrease gradually. In the case of a 50 ml bottle, leaving it at room temperature will empty in 2 to 3 weeks.
Liquid does not leak, but there may be subtle gaps where gas escapes.
Or, since dichloromethane has a vapor pressure of about 50 kPa at 20 ° C, the total pressure inside the container rises to about 1.5 atm, and as the pressure continues for a long time, the lid may slightly relax to the extent that the gas leaks out. not.
If it is a liquid with a high boiling point such as ethanol, there will be some volatilization, but there is no worry that it will diminish.
I think that it is better to choose a container with an inner lid for highly volatile liquids (boiling point 30 to 70 ° C) such as diethyl ether, dichloromethane, carbon disulfide, dichloroethylene, acetone, chloroform, methanol.
If you use this container, you should take measures such as keeping it in a refrigerator etc. at low temperature, putting it in a pressure vessel etc and storing it at 2 atm or more.
