Glass-backed Analytical TLC Plates

Miles Scientific Analtech Brand UNISIL Silica Gel G Thin Layer Chromatography (TLC) Plates, scored - Glass-backed - 250µm thickness - 10x20cm - 25 plates per box - 10μm particle, 60Å pore

Product Number: P30521

Weight: 7.10 LBS

• G - (Gypsum) Calcium Sulfate Hemihydrate binder

UNISI™ Silica Gel G & GF UNIPLATES™

These plates are prepared using a special high purity silica gel with a calcium sulfate binder. UNISIL UNIPLATES offer exceptional discrimination for aflatoxins compared to other adsorbent layers.

Analtech Brand Silica Gel G / GF TLC Plates

• Silica Pore: 60Å
• Silica Particle Size: 8-10 μm average
• Binder: Calcium sulfate a.k.a. gypsum (inorganic)
• Hardness: 20-40

Acceptable Solvents:

All typical chromatography solvents (20% water max)

Visualization Techniques:

Compatible with essentially all visualization reagents, even sulfuric acid charring. Spraying reagent is suggested; layer is incompatible with aqueous dipping technique.

General Description:

Considered to be the original “Classic” TLC plate. Gypsum (calcium sulfate) binder produces softer layer for easy scraping and removal of spots or bands for further analysis. This is the best choice when preparative work is needed using thicker coatings to isolate larger quantity of material. Because the binder is inorganic, it is compatible with aggressive visualization techniques such as sulfuric acid charring. Limited water tolerance due to slight solubility of calcium sulfate in water precludes dipping procedure but is applicable with spray techniques.

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.
