Analtech Brand Silica Gel H / HF TLC Plates

• Silica Pore: 60Å
• Silica Particle Size: 8-10 μm average
• Binder: Proprietary polymer (organic)
• Hardness: 200-400 (easy to write on with pencil)

Acceptable Solvents:

All typical chromatography solvents (80% water max)

Visualization Techniques:

Compatible with most visualization reagents except sulfuric acid charring. Reagent may be dipped or sprayed. Some incompatibility with certain acidic reagents.

General Description:

Best layer choice unless contra-indicated by noted incompatibilities of visualization reagents or mobile phase composition. Hard layer organic binder system is the most rugged, providing easy handling of layer during sample application, mobile phase development, visualization and data interpretation. Rugged layer surface provides consistent results independent of operator technique. Quick development times and uniform visualization properties provide lot-to-lot consistency and reduce seasonal variability in chromatography.

Silica Gel H & HF UNIPLATES contain no calcium sulfate binder. The adsorbent contains a small amount of colloidal silica which aids in the adherence to the glass plate.

Prep-Scored UNIPLATES™

Prep-Scored UNIPLATES are designed especially for preparative TLC procedures where destructive visualization techniques must be used to locate separated zones.

Prep-Scored UNIPLATES are scored 2.5 cm from each vertical edge. After developing, the 2.5 cm strips between each score mark and the edge can be easily “snapped” away from the center portion of the plate.

Visualization of separated zones on these 2.5 cm strips followed by realignment with the center portion provides a convenient method for locating zones to be recovered by scraping.
