Plastic Base TLC

Plastic backed TLC plates. Polyester sheets (about 0.2 mm thick) have several advantages: its resistant towards all common solvents need less packing and less shelf space for storage. The plastic backed TLC plates can be easily cut with scissors into any required size, and the spots can be cut and eluted.  Charring techniques can be applied for silica coated plastic TLC plates.  The charring has to be done at lower temperatures than on glass. The maximum temperature for plastic TLC plates is 160 °C.
