Analtech UNIPLATES are 250 microns thick for regular analytical TLC and between 500 and 2000
microns for preparative TLC. Tapered preparative UNIPLATES have a wedge-shaped layer 300μm to 1700μm with a 700μm preadsorbent area (see notes on page 9). High Performance UNIPLATES have a thinner layer of adsorbent between 150-200 microns. All thickness designations are nominal. Actual thicknesses may vary but are consistent from batch to batch.
UNIPLATES are available in the following standard sizes: 20 x 20 cm,10 x 20 cm, 5 x 20 cm as well as 2.5 x 10 cm and 2.5 x 7.5 cm. The standard size for High Performance UNIPLATES (HPTLC) is 10 x 10 cm, although they are available in other sizes. Analtech will be happy to supply your special TLC plate requirements (such as 20 x 40 cm plates) whenever it is within our capability to do so.
