Confirm residual Ag ion
On 2018-01-17 16:02:13
Since so strict examination is unnecessary, put a saturated sodium chloride solution and use it to check whether white turbidity can be observed by dropping a few drops. It is not particularly good, there are also no disadvantages, it is quite common. I think that it is good if the change of rubber part does not disappear.
Making a prototype

Tightening of the cap is hard when putting on or removing the cap.
Bottles for perfuming

I am helping. Since the dropper part is rubber, it is easy to degrade, so I want you to prepare silicone rubber. I am satisfied surprisingly surprisingly.
Preservation of turpentine oil

I replaced the rubber part of the dropper with silicone rubber and used it to preserve turpentine oil, but the cap melted. Oil may have leaked out when the bottle collapsed. I think that it is not a bad bottle, but it seems to be inappropriate for turpentine oil.
When paint is stored / painted

Place the shellac diluted with alcohol and use it by suctioning with a dropper. It can be used without problems. This size is sufficient when painting guitar shellac.
I use aroma, lotion etc.

I use it for aroma, but it is convenient to use it in several kinds. I find it useful in an appropriate capacity.
Storage of liquid

I would like you to sell silicone rubber products, not natural rubber. Moreover, it is not a change of rubber, but it is already a product. There was that product in the HP of Maruem.
Preparation of EO

I can use it with confidence that the rubber of the eyedropper is somewhat stronger ...
Essential oil filling

When putting volatile liquid such as essential oil, it dissolves the dropper rubber. I would like you to handle not only natural rubber but also silicon eyedropper version.

There is also no leakage, and since the glass is thick, it is safe. I am also glad with the cap.
