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.

Scored UNIPLATES™

Most UNIPLATES can be supplied with the glass backing scored at specific locations to permit convenient “snapping” into smaller plates. This Analtech feature provides increased versatility and can mean cost savings over plates already cut to smaller sizes.

Different adsorbents, mobile phases, and analytical conditions can be tested quickly and economically. A plate can be spotted, then snapped into several smaller plates for developing in different solvent mixtures to determine the best separation.

A plate can be spotted, developed, then snapped into several smaller plates, and then subjected to different visualization techniques.

Scored UNIPLATES are available in two standard formats:

1) 20 x 20 cm scored UNIPLATES have three score marks 5 cm apart. Each plate can be snapped to produce four 5 x 20 cm plates or any multiple of 5 cm width.

2) 10 x 20 cm scored UNIPLATES have seven score marks 2.5 cm apart. Each can be snapped to produce eight 2.5 x 10 cm plates or any multiple of 2.5 cm width.
