What Type Of TLC Backing To Choose? -

TLC plates are available with different backings (also called supports): rigid (glass-backed) or flexible sheets (aluminum plastic-backed). Glass-backed plates are the most frequently used due to the ease of handling, transparency (spot can be seen on both sides) as well as the chemical resistance and inertness of the support. However, glass plates also present certain disadvantages like
