Alphagem Bio microcentrifuge tubes are meticulously designed to meet a wide range of research applications and are ideal for different sample preparations, storage, and centrifugation tasks. Our microfuge tubes are manufactured with ultra-premium medical-grade plastic, which offers optimal chemical resistance and preserves the sample's integrity. The rugged design of our microfuge tubes can fit the most common rotors and is able to withstand rigorous centrifugation for up to 20,000 RCF due to their exceptional durability. Furthermore, our tubes are also engineered to endure extreme temperatures as low as -80°C, making them perfect for cryogenic applications. For enhanced convenience, our tubes feature flat lids to form a secure, leak-free seal and can easily open even when wearing gloves. The positive-seal design keeps the tube caps securely closed during denaturation and even in boiling water baths. Our microfuge tubes are autoclavable at 120°C, providing hassle-free sterilization, and are available in various sizes along with writing space and volume marks on the sidewalls for easy labeling.
