• Upgraded Material, Robust and Durable: made with borosilicate glass (heat-resistant glass), it boasts higher hardness and thermal stability compared to ordinary glass; The thickened tube design significantly enhances impact and wear resistance, making it less prone to breakage during frequent daily use, ensuring durability and reducing long-term consumable costs
• Clear and Precise, Easy to Read: the straight and transparent tube with uniform wall thickness provides a clear view of liquid flow; Combined with clear and precise milliliter graduations, it effectively assists users in achieving high-precision liquid volume and transfer, minimizing experimental errors and ensuring the reproducibility of experimental results
• Fine Tip, Easy Operation: the compact design of the aspiration tip allows for easy insertion into narrow-mouth reagent bottles or sample containers, enabling flexible and unimpeded pipetting; The tip is professionally flame-polished, creating a smooth and rounded break, allowing for safe and comfortable connection to various pipette tips/bulbs while avoiding the risk of scratches
• Wide Application, High Durability: this product is an indispensable liquid transfer tool in chemical analysis, biological experiments, clinical testing, and teaching demonstrations; Its glass material possesses excellent chemical corrosion resistance and high-temperature resistance, allowing for easy high-temperature and high-pressure sterilization; It is suitable for various rigorous scenarios such as cell culture, reagent addition, and sample preparation
• Bulk Packaging, Ample Quantity: we offer economical large packs of 500 pieces each, fully meeting the high-frequency consumption needs of laboratories; Understanding the characteristics of glass products, we also include extra spare pieces with each pack, providing immediate replenishment for any non-human-caused breakage and ensuring uninterrupted experimental processes
