These capillary tubes feature a 0.3mm inner diameter and 0.5mm outer diameter, with a standard 100mm length and both ends open. Made from high-quality, clear borosilicate glass, they offer excellent chemical resistance and thermal stability for reliable lab performance.
Designed specifically for Thin Layer Chromatography (TLC) applications. They are perfect for precise sample spotting on TLC plates, ensuring clean, accurate results for your chemical analysis, research, and educational experiments.
We understand the fragility of glass. That's why each set of 1000pcs capillaries is meticulously organized and cushioned in a sturdy, foam-lined container to prevent breakage during transit, ensuring they arrive at your lab intact and ready to use.
Beyond TLC spotting, these micro glass tubes are also great for melting point determination, micro liquid transfer, collecting small samples, and as delicate pipettes in various scientific experiments and DIY projects.
We are committed to providing consistent and high-quality lab consumables. Each capillary tube is inspected for clarity and integrity. If you receive any damaged items, please contact us for a prompt solution.
