Preparative TLC plates feature thicker adsorbent layers and are useful for separation of larger quantities of material than plates with a 250 µm thick coating.

• Thicker layers for higher capacity
• Full range of plate sizes
• Prep-scored option for convenient zone location
• Available with preadsorbent sample loading zone
• Calcium sulfate binder soft later for easy scraping

When materials to be separated are applied in long streaks, specific compounds can be recovered after development by scraping the adsorbent layers from the plate in the region of interest and eluting the separated material from the adsorbent using a strong solvent.
