TLC-plates SILGUR-25 UV254, 10x20 810022

Unmodified standard silica layers with concentrating zone for TLC

Silica 60, specific surface (BET) ~ 500 m2/g, mean pore size 60 Å, 
specific pore volume 0.75 mL/g, particle size 5–17 µm
available as glass plates with or without fluorescent indicator
also available as ALUGRAM® Xtra aluminium sheets 
Excellent separation efficiency
Easy and reliable cutting
Outstanding wettability

Also available as channeled glass plate:
Channel-plate with 19 channels help to prevent cross contamination by separating several samples. More samples can be separated on a plate, and spot areas can be more easily determined.

Kieselguhr zone for rapid sample application: 
Because kieselguhr is completely inert towards a large number of compounds, the samples always form a narrow band at the interface of the two adsorbents, irrespective of shape, size or position of the spots in the concentrating zone (see figure). Separation then takes place in the silica layer.
