About Laboratory And Industrial Marking Applications, Different Product Recommendations For Alcohol-resistant Pens

The main laboratory use is to needles with 70-75% medical alcohol. At present, customers are mostly using American Sanfu Sharpie double-headed pens. However, the alcohol resistance of these pens is not ideal. When photographed on a glass plate, the pen will discolor when it comes into contact with alcohol. For laboratory and industrial use, a geemaker industrial test pen has been released: G-3201 (writing line width about 1.0mm), G-3501 (writing line width about 1.5mm). When it comes into contact with 90% or less alcohol, the surface will not discolor. Oil-based ink, quick drying, can meet the needs of laboratory and industrial marking. 75% medical alcohol is commonly used in the laboratory to prevent fading, so there is no problem. For industrial use, with an industrial alcohol content of over 90%, we recommend three different Artline brand grease pens. These grease pens have better resistance to industrial alcohol than similar products. However, grease pens have better performance than other similar products. However, they may not be suitable for use in the laboratory. First of all, the way grease pens are used is different from the grease pens we use in everyday life, and they can be used to numb people. Secondly, the slowness of drying oil paint brushes, which may be the main reason why many customers choose oil paint brushes.
