The choice of stationary phase is the most critical factor in achieving high-resolution separations in thin layer chromatography. LabFriend offers an extensive selection of TLC plates, located within the thin-layer chromatography section of our chromatography department. These professional-grade plates are available in various formats and backings to suit diverse analytical and preparative requirements.
Why Choose Professional TLC Plates & Sheets?
Our curated collection of stationary phases is engineered for uniform layer thickness, high mechanical stability, and excellent reproducibility:
- High-Performance Precoated Plates: We stock Macherey-Nagel TLC Precoated Plates SIL G-25 and SIL G 25 UV 254 (20x20 cm), featuring a robust silica layer for reliable routine analysis.
- Durable Aluminum Backed Sheets: Utilize Macherey-Nagel Alugram Sheets Sil G and Alugram Xtra Sheets, known for their ease of cutting and high resistance to aggressive development reagents.
- Specialized UV Detection: Explore Polygram SL GUv 254 and Alugram GUV254 sheets, which include a fluorescent indicator that allows for the non-destructive visualization of UV-active compounds.
- Premium Foil Options: Our range includes Merck DC-Alu Foil Silica Gel 60 F254 (20 x 20 cm), a global industry standard for high-quality chromatographic separation and stability.
LabFriend supplies TLC plates from manufacturers trusted globally for separation excellence:
- Macherey-Nagel: A world leader in chromatography, providing the comprehensive Alugram and Polygram series of silica-coated sheets.
- Merck: Renowned for analytical precision, offering the classic Silica Gel 60 foil series used in laboratories worldwide.
- Hahnemühle: Providers of specialized filtration and paper-based stationary phases for unique separation and blotting applications.
Reliable chromatography starts with the plate but ends with detection; to further enhance your TLC workflow, we recommend exploring these related categories:
- TLC Chambers: Ensure uniform development of your Macherey-Nagel or Merck plates using Bionis separating chambers.
- TLC Detection: Visualize separated spots on your UV254 plates using Vilber viewing cabinets or Bionis reagent sprayers.
- TLC Accessories: Use Bionis plate cutters to resize your Alugram sheets without damaging the silica layer.
- Microlitre Syringes: Apply precise sample volumes to your stationary phase using Hamilton or Trajan analytical syringes.
Unsure whether aluminum, plastic, or glass-backed plates are best for your specific solvent system? Our team provides local technical support to help you find the perfect plate solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. What is the advantage of "UV 254" in TLC plates?
Plates with a UV 254 indicator, such as Macherey-Nagel Alugram GUV254, allow you to see colorless compounds that absorb UV light as dark spots against a glowing green background.
2. Can Alugram sheets be easily cut to size?
Yes, aluminum-backed Alugram sheets are designed to be easily trimmed with standard laboratory scissors or a Bionis plate cutter for smaller-scale separations.
3. What does "Silica Gel 60" refer to?
Silica Gel 60 refers to the pore diameter of the silica particles (approximately 60 Ångströms), which is the standard size for most routine small-molecule TLC separations.
4. Are there plates suitable for large preparative separations?
While many of these plates are for analytical use, Macherey-Nagel provides thicker precoated layers specifically designed for preparative TLC where higher sample loading is required.
