SIL G/UV254, 20x20cm

SIL G unmodified standard silica layers for TLC, glass plates/ POLYGRAM®

Support materials for TLC ready-to-use layers

Glass plates: glass, ~ 1,3 mm thick, high requirments for weight, packaging and storage, ideal torsional strength, high temerature stability, susceptible to breakage, can not be cut with scissors, high resistance against solvents, mineral acids and conc. ammonia, suitability for aqueous detection reagents depends on the phase

POLYGRAM®: polyester, ~ 0,2 mm thick, low requirments for weight, packaging and storage, low torsional strength, max. 185°C temerature stability, not susceptible to breakage, can be cut with scissors, high resistance against solvents, mineral acids and conc. ammonia, very suitable for aqueous detection reagents

ALUGRAM®: aLuminium, ~ 0,15 mm thick, low requirments for weight, packaging and storage, relatively high torsional strength, high temerature stability, not susceptible to breakage, can be cut with scissors, high resistance against solvents, low resistance against mineral acids and conc. ammonia, limited suitable for aqueous detection reagents
glass plates, POLYGRAM®, ALUGRAM®

silica 60, specific surface (BET) ~500m²/g, mean pore size 60 Å, specific pore volume 0.75 ml/g, particle size 5 to 17µm; standard grade thickness of layer for analytical plates 0.25mm, for preparative plates 0.5 and 1mm; for 2mm preparative layers a slightly coarser material is used indicators: manganese activated zinc silicate with green fluorescence for short-wave UV (254nm); special inorganic fluorescent pigment with blue fluorescence for long-wave UV (366nm)
binders: highly polymeric products, which are stable in almost all organic solvents and resistant towards aggressive visualisation reagents; binder system for Polygram® sheets is also completely stable in purely aqueous eluents
available as glass plates, Polygram polyester sheets and Alugram aluminium sheets.
Available as glass plates with or without fluorescent indicator (UV254).
