Miles Scientific Analtech Brand Silica Gel H Thin Layer Chromatography (TLC) Plates - Scored (2.5x20cm) - Glass-backed - 250µm thickness - 20x20cm - 25 plates per box - 19μm particle, 60Å pore

Product Number: P10311

Weight: 11.10 LBS

• H - Binder-free adsorbent

Analtech Brand Silica Gel H / HF TLC Plates

• Silica Pore: 60Å
• Silica Particle Size: 19 μm average
• Binder: none
• Hardness: 1-8

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. 

Acceptable Solvents:

All typical chromatography solvents (20% water max) Visualization Techniques: Compatible with essentially all visualization reagents, even sulfuric acid charring. Spray reagent only. Dipping not recommended.

General Description:

Very soft surface as no binder is used to adhere the layer to the glass backing. Requires extra caution during use to prevent damage to the layer, which would affect chromatography. However, it is sometimes required when the separation being run is sensitive to any materials other than silica gel in the chromatographic process. Compatible with most mobile phases except water in excess of about 20%. Dip visualization procedures not recommended, but plates do tolerate gentle spray techniques.

Silica Gel H & HF UNIPLATES™ – Binder Free

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.
