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 requirements for weight, packaging and storage, ideal torsional strength, high temperature 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 requirements for weight, packaging and storage, low torsional strength, max. 185 °C temperature 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 requirements for weight, packaging and storage, relatively high torsional strength, high temperature stability, not susceptible to breakage, can be cut with scissors, high resistance against solvents, low resistance against mineral acids and conc. ammonia, limited suitability for aqueous detection reagents
Glass plates, POLYGRAM®, ALUGRAM®
  • Silica 60
  • Specific surface (BET) ~500 m²/g
  • Mean pore size 60 Å
  • Specific pore volume 0.75 ml/g
  • Particle size 5 to 17 µm
  • Standard grade
  • Thickness of layer for analytical plates 0.25 mm, for preparative plates 0.5 and 1 mm
  • For 2 mm preparative layers a slightly coarser material is used, indicators: manganese activated zinc silicate with green fluorescence for short-wave UV (254 nm)
  • 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 with or without fluorescent indicator (UV 254)
