They are manufactured from sturdy moulded glass bricks that will withstand regular use for many years. The clear
sides allow unobstructed visual inspection of TLC plates up to 20 x 20 cm. The top of the tanks has been ground to a
uniform flatness for perfect lid and the edges have been bevelled to remove any sharp edges. The bottoms are ground
to provide a flat, level surface.
A special model with thick-walled clear glass tank grooved is designed to accept up to five 200x200 mm TLC plates, and it is particularly used for quantitative analysis, serving also to store plates in a protected environment.
