Silgur unmodified standard silica layers with concentrating zone

Silgur unmodified standard silica layers with concentrating zone
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

silica 60, specific surface (BET) ~ 500m2/g, mean pore size 60Ä, specific pore volume 0.75ml/g, particle size 5.17µm
kieselguhr zone for rapid sample application: because kieselguhr is completely inert towards a large number of compounds, the samples always from a narrow band at the interface of the two adsorbents, irrespective of shape, size or position of the spots in the concentrating zone. Separation then takes place in
the silica layer.

available as glass plates with or without fluorescent indicator (UV254)
