Featuring seamless round-bottom construction and fully transparent tube body, it allows direct, unobstructed observation of liquid samples, chemical reactions and specimen states. Made of high-strength borosilicate glass, this test tube delivers excellent thermal-shock resistance, tolerating heating and rapid temperature variation without cracking. Uniform tube wall ensures stable mechanical performance. The open-top round-bottom design fits well for lab heating, reagent mixing, sample holding, teaching experiments and decorative display purposes. Widely applied in laboratories, schools, biotech institutions, cosmetic sampling and DIY decorative projects. Key Features & Benefits: Excellent Optical Clarity - Fully transparent borosilicate glass provides distortion-free viewing, convenient for observing chemical reactions, color changes and sample conditions. Round-Bottom Seamless Construction - Smooth seamless round-bottom avoids residual dead corners, facilitates complete liquid pouring and thorough cleaning. Superior Thermal-Shock Resistance - Premium borosilicate glass withstands sharp temperature fluctuation, safe for direct heating, resistant to cracking under hot-cold alternation. Chemical Inert Performance - Non-reactive glass surface will not react with most chemical reagents, guaranteeing sample purity for experimental accuracy. Uniform Tube Wall Thickness - Consistent wall thickness lowers internal stress, improves mechanical strength and reduces breakage risk during operation. Open-Top Convenient Operation - Plain open mouth supports reagent adding, liquid transferring, sample stirring and heating work for lab workflows. Easy to Clean & Reusable - Smooth inner and outer glass surface resists residue adhesion, simple washing for repeated lab or decorative use. Eco-Friendly & Sustainable - 100% lead-free borosilicate glass, fully recyclable, complying with global environmental-protection requirements. Customizable - Custom length, outer diameter, wall thickness and mouth treatments are available for OEM & ODM, flexible minimum order quantity. Applications & Use Cases: Laboratory Scientific Work - Chemical reaction testing, liquid reagent storage, biological specimen holding, lab sample analysis.
