General description
25 Glass plates 5 x 10 cm
Our classical silica TLC plates are based on a combination of our proven silica gel 60 and the addition of a unique polymeric binder resulting in a very adherent and hard surface that will not crack or blister and even allow writing with a pensil on the surface without risk to damage the layer.
Application
Glass TLC plate, silica gel coated with flourescent indicator F254. The silica gel TLC plates come in a quantity of 25 size 5x10 cm for thin layer chromatography applications.
Analysis Note
Specific surface area (according to BET; 5-Pt. measurement): 480 - 540 m²/g
Pore volume (N₂-isotherm): 0.74 - 0.84 ml/g
d 50 (laser diffraction, size distribution): 9.5 - 11.5 µm
Layer thickness: 210 - 270 µm
Deviation of layer thickness per plate: ≤ 35 µm
Chromatographic testings:
A) Colour test
hRf-values
- bleu vif organol, colour test, lipophile:
11 - 25
- Ceres Black G, colour test, lipophile: 34 - 48
- ceres Violet brn, colour test, lipophile: 52 - 67
separation number (colourtest, lipophile): ≥ 9.0
B) Steriod test
hRf-values
- hydrocortisone, steroid test:
