Porous silica gel having pore size of 7 nm (70 Å) and uniform particle size is evenly applied to the glass plates.  Four types, including types containing and not containing fluorescence indicators, are available. It is easy to switch to preparative chromatography with Wakogel® LP Series or Wakogel® C Series.

Features
  • Uniform particle size of raw material silica gel from 5 to 15 μm
  • Enhanced spot convergence and improved separation ability
  • Use of new binder, and excellent peeling resistance to organic solvents and chemical resistance
Silica Gel 70 Plate-Wako

A fluorescence indicator is not contained. Spots can be detected by spraying a color reagent (sulfuric acid, ninhydrin, iodine, etc.). It is useful in selective detection of fluorescent substances.

Silica Gel 70FM Plate-Wako

Three kinds of fluorescent substances in three primary colors of light, red, green and blue, are added to FM Plate. Under irradiation with wide-range UV rays (λ= 250 ~ 400 nm), the spots show ultraviolet region absorption specific to the substances and are observed as spots colored in red, blue, etc. on the white ground.

Silica Gel 70F254 Plate-Wako

Since this plate contains a green fluorescent substance, separated spots are detected as dark spots on the green ground under ultraviolet (λ= 254 nm) irradiation.

Silica Gel 70PF254 Plate-Wako

This product is a TLC plate for fractionation in Silica Gel 70 Plate Series. Sampling can be easily performed because the quantity of binder is extremely reduced.
