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.

Because it is a wide mouth, it is good that materials are easy to put in and firm. However, we are using it while we are careful because there is a weak part in the solvent. I think that it is even better if there is an inner lid
