Glass test tubes are made of borosilicate glass, which features high temperature resistance and chemical corrosion resistance. They reduce pH variations and contamination caused by precipitates from soda-lime glass. All test tubes have uniform bottoms, polished rims and consistent lengths, and are packed in convenient heat-shrink film boxes. They can be used for mixing, heating or holding small quantities of chemical reagents for analysis, as well as for tissue culture, blood bank operations and other laboratory tests.
1. Our lab glass test tube is made of high-purity 3.3 borosilicate glass, withstanding 300℃ and 99% strong acids/alkalis. It reduces pH variations by 95% and soda-lime glass contamination to ≤0.001mg/cm², making this borosilicate glass test tube ideal for professional labs.
2. Each glass test tube boasts precise craftsmanship: bottom thickness error ≤0.1mm, polished rims (Ra ≤0.8μm), length error ±0.5mm. With 98% light transmittance and seamless molding, it ensures leak-proof and clear reagent reaction observation.
3. Our borosilicate glass test tube has 200℃ thermal shock resistance, avoiding cracking during rapid heating/cooling. 560℃ annealing boosts toughness by 30%, reducing breakage rate to ≤0.5% and cutting your laboratory operational costs.
4. We offer glass test tubes with caps (5ml-50ml), caps made of food-grade cork. 100% sealing prevents reagent volatilization and cross-contamination, reusable after sterilization, perfectly matching our lab glass test tube.
5. All glass test tubes are packaged in moisture-proof heat-shrink film boxes . Each batch passes strict inspection (99.8% qualified), with ISO9001/CE certifications.
6. Our lab glass test tube is versatile for reagent mixing, heating, tissue culture and blood bank use. Widely applied in chemical/medical fields, it supports customization (scale printing, logo), fitting your specific needs.
1. In chemical laboratories, the lab glass test tube is widely used for mixing reagents, heating samples and conducting routine chemical reactions. It resists chemical corrosion, ensuring no contamination and maintaining the accuracy of experimental results for researchers.
2. For biological experiments, the borosilicate glass test tube is ideal for preliminary cell and microorganism culture. Its high temperature resistance and stability prevent sample pollution, supporting safe and reliable biological sample pretreatment.
3. In medical testing and blood banks, the glass test tube is used to hold blood, body fluids and other samples. It is sterile, non-toxic and easy to clean, meeting the strict hygiene requirements of clinical testing and sample storage.
4. In educational institutions, the lab glass test tube is a necessary teaching tool. It intuitively demonstrates chemical reactions and biological phenomena, helping students better understand experimental principles in science and chemistry courses.
5. In food and pharmaceutical quality control, the glass test tube holds extracts and stock solutions for physical and chemical testing. It ensures no component precipitation, helping enterprises strictly control product quality and safety.
6. For DIY and small-batch production, glass test tubes with caps are perfect for subpackaging essential oils, fragrances and small reagents. Their tight sealing prevents volatilization, suitable for handmade beauty and aromatherapy.
1.Before use, clean and dry your glass test tube thoroughly.
2.When heating liquid, fill no more than two‑thirds of the tube and heat gently to avoid splashing.
3.Use glass test tubes with caps for sealed storage to prevent leakage.
4.Do not heat empty tubes or apply sudden extreme temperature changes to ensure safe and long‑term use.
