Leak-Proof Performance Guaranteed

Each microtube features a screw cap with an integrated silicon ring to ensure a reliable, leak-proof seal. This design prevents sample evaporation and contamination during storage, centrifugation, or transport. The robust structure supports repeated usage, even after multiple autoclave cycles, enhancing both safety and cost-efficiency for laboratory workflows.


Versatile Laboratory Applications

Ideal for sample storage, cryogenic preservation, PCR reactions, enzyme assays, and molecular biology, these tubes are built for compatibility with standard microcentrifuge rotors. Their chemical and temperature resistance make them suitable for various demanding procedures, ensuring sample integrity from preparation to analysis.


Sterile and Reusable Convenience

Available in sterile and non-sterile bulk packs, these microtubes can be reused after autoclaving, maintaining their integrity and sealing capacity. The natural transparent tubeswith optional colored screw capsfeature easy-to-read graduation marks, facilitating accurate sample volume checks and hassle-free identification.

FAQs of Self-Standing 0.7ml Screw Cap Microtubes with Silicon Ring:


Q: How do I ensure that the microtubes remain leak-proof during centrifugation or storage?

A: A leak-proof seal is achieved through the integrated silicon ring in the screw cap. Always tighten the cap fully before use to maximize sample protection, especially during centrifugation up to 20,000 x g or cryogenic storage.

Q: What applications are suitable for these 0.7ml microtubes?

A: These microtubes are ideal for sample storage, cryogenic preservation, PCR reactions, enzyme assays, and general molecular biology workflows. Their design supports safe centrifugation, chemical handling, and temperature fluctuations.

Q: When should I use sterile versus non-sterile packs of these microtubes?

A: Sterile packs are recommended for sensitive applications where contamination must be avoided, such as molecular biology or clinical sample storage. Non-sterile packs are suitable for less critical processes or general laboratory use.

Q: Where can I use these microtubes within my laboratory equipment?

A: The microtubes are self-standing for bench use and compatible with standard microcentrifuge rotors, allowing integration into common laboratory protocols and automated processes.

Q: What makes these tubes reusable after autoclaving?

A: Manufactured from high-grade polypropylene and equipped with a durable silicon sealing ring, these microtubes retain their shape, seal, and clarity after multiple autoclave cycles (up to 121C). They maintain sterility and leak-proof performance, reducing waste and expenses.

Q: How do molded graduation marks benefit laboratory processes?

A: The molded graduation marks enable quick, visual confirmation of sample volume. This assists with accurate pipetting, aliquoting, and reduces the risk of measurement errors during experimental setup.

Q: What are the benefits of the DNase, RNase, and pyrogen-free certification?

A: Being DNase, RNase, and pyrogen-free ensures the tubes will not introduce nucleases or contaminants into samples. This is crucial for molecular biology, PCR, and sensitive enzyme assays, bolstering reproducibility and reliability of results.
