80 Pack Layer Chromatography TLC Plates with Silica Gel, 2.5 × 7.5 cm Glass-Backed Chromatography Plates with Spotting Tubes, High Sensitivity TLC Sheets for Lab Chemistry,Organic Analysis

Enhance your laboratory efficiency with this 80-pack of glass-backed Thin Layer Chromatography (TLC) silica gel plates, complete with capillary spotting tubes. Each plate is precisely manufactured to 2.5 × 7.5 cm (25 × 75 mm), with a 200 μm ± 30 μm silica layer, 0.4–0.5 mm total thickness, and >500 mesh particle size—providing uniform consistency across every experiment. Crafted from high-purity silica gel GF254 with a polymeric binder, calcined gypsum, and fluorescent indicator, these plates maintain stable chemical properties, reacting only with strong bases and hydrofluoric acid. This ensures reliable analytical results without deviations from material interference, even under varied laboratory conditions. Engineered for fast, high-sensitivity separation, the plates produce clear, non-diffusing spots that are easily visible under UV light. Their high theoretical plate count and fine spot resolution support both qualitative organic analysis and quantitative thin-layer scanning, delivering precise and dependable data every time. Unlike other plates requiring pre-treatment, these ready-to-use TLC plates streamline workflows by eliminating preparation steps, saving valuable time in fast-paced labs. Perfect for routine testing, teaching, or rapid detection applications, they provide professional-grade performance straight out of the box. Versatile in use, these chromatography plates are widely employed in biochemistry, pharmaceutical analysis, food safety testing, and environmental monitoring. Whether for drug purification, educational experiments, or environmental sample separation, this set offers a dependable, cost-effective solution for labs of all sizes.

• 【Bulk 80-Pack with Spotting Tubes】Each set includes 80 TLC silica gel plates (2.5 × 7.5 cm / 25 × 75 mm) and capillary spotting tubes. Uniform specifications—200 μm ± 30 μm layer thickness, 0.4–0.5 mm total thickness, >500 mesh particle size—ensure consistent performance for batch lab experiments and repeated testing.
• 【Premium Silica Gel GF254】Constructed from unmodified silica gel and polymeric binder with SiO₂·nH₂O as the main component, plus calcined gypsum and fluorescent indicator. Chemically stable, reacts only with strong bases and hydrofluoric acid, offering excellent resistance to interference in different experimental environments.
• 【Fast & Accurate Analysis】Delivers short separation time, high sensitivity, and clear, non-diffusing spots that can be directly observed under UV light. With a high number of theoretical plates and minimal spot size, it is ideal for both qualitative analysis of organic substances and thin-layer scanning quantitative analysis.
• 【Ready-to-Use Convenience】Classic glass-backed TLC plates require no additional pretreatment—simply open the box and use them immediately. Save time, reduce preparation workload, and improve efficiency in routine testing or rapid detection experiments.
• 【Wide Laboratory Applications】Widely applied in biochemistry, pharmaceuticals, food safety testing, and environmental monitoring. Suitable for universities, research institutes, teaching labs, and professional testing facilities, meeting diverse needs for substance separation, purification, and identification.
