Types of the sample vial
sample vials are generally divided into three types: sample bottles with clamps, screw caps, and bayonet caps
How to choose the three sample vials?
The sealing of the clamp bottle itself is, of course, better than the threaded bottle, rubber or silica gel after puncture also has a good re-sealing, so it is ideal to preserve the reagent.
But if in the use of some organic solvent corrosion silicone or rubber bottle mat, so you need a bottle of PTFE coating, mat, if, in the use of reagent is not a finished, but in the sample bottle part such as the next reoccupy, then finished samples will evaporate, with a bottle of a PTFE coating pad after puncture seal will be lost.
It is recommended that some of the reagents without corrosion to the rubber or silica gel bottle pad can be stored in a clamp bottle, while for corrosive reagents, it is not recommended to use a clamp bottle seal. Compared with silicone, rubber has a better sealing property.
Bayonet sample bottles and bottle caps are simple and effective ways to ensure sealing without clamps. It’s as easy as pressing in and pulling out. The clamshell lid can also be used with a jar. The sample vial with a bayonet cap cannot be pressurized.
