설명

일반 설명

Standardized sorbents ensure reliable results every time. Our broad spectrum meets all kinds of needs. In TLC, silica gel 60 sorbent is considered the most versatile. Our assortment of silica gel 60 features different grades with particle sizes ranging from 5-40 µm: silica with a gypsum binder, silica with no foreign binder, and silica gel with a fluorescence indicator. We also offer high-quality aluminum oxide, cellulose microcrystalline, and kieselgur (also known as diatomaceous earth).
