Macherey-Nagel ALUGRAM SIL G/UV254 sheets are high-quality unmodified standard silica layers for thin-layer chromatography (TLC), available on aluminium supports for reliable analytical and preparative applications.
Product Features
- Unmodified standard silica layers for TLC, available as glass plates, POLYGRAM polyester sheets, or ALUGRAM aluminium sheets
- ALUGRAM sheets: aluminium, ~0.15 mm thick, low weight and packaging requirements, relatively high torsional strength, high temperature stability
- Not susceptible to breakage and can be cut with scissors
- High resistance against solvents, low resistance against mineral acids and concentrated ammonia
- Limited suitability for aqueous detection reagents
- Silica 60 with specific surface (BET) ~500 m²/g, mean pore size 60 Å, specific pore volume 0.75 ml/g, particle size 5–17 µm
- Standard grade; layer thickness for analytical plates 0.25 mm, preparative plates 0.5–1 mm (2 mm layers use slightly coarser material)
- Fluorescent indicator: manganese-activated zinc silicate with green fluorescence for short-wave UV (254 nm)
- Binders: highly polymeric, stable in almost all organic solvents and resistant to aggressive visualisation reagents
- Pack quantity: 200 sheets per pack
Benefits
- Reliable and reproducible TLC separation for analytical and preparative work
- Durable aluminium support provides resistance to breakage and high temperatures
- High chemical and solvent resistance ensures long-lasting performance
- Fluorescent indicator allows easy visualization under UV 254 nm
