Glass-backed Analytical TLC Plates

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

Product Number: P10911

• 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.

Channeled UNIPLATES™

Channeled UNIPLATES are available in a variety of adsorbents and plate sizes including the preadsorbent format. These plates have 9 mm wide adsorbent tracks which are separated by 1 mm wide channels where the adsorbent layer has been removed. Channeled plates prevent cross contamination and the spreading of the sample components during development.
