Glass-backed Prep TLC Plates

Miles Scientific Analtech Brand Silica Gel H Prep Thin Layer Chromatography (TLC) Plates, with Magnesium Acetate, Prep Scored - 500µm Thickness - Glass-backed - 20x20cm - 25 plates per box

Product Number: P88002

Weight: 15.10 LBS

• H - Binder-free adsorbent

Magnesium Acetate (%) Modified Silica Gel H & HF UNIPLATES™

These Silica Gel H UNIPLATES are prepared with 5%, 7.5%, or 10% magnesium acetate as the slurry liquid. The addition of magnesium acetate decreases the acidity of the layer and allows increased discrimination of phospholipids. The concentration of magnesium acetate added to the layer must be specified at the time of order (7.5% is most commonly used)

Analtech Brand Silica Gel H / HF TLC Plates

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

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.

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.
