Frequently Asked Questions

What are these screw cap microcentrifuge tubes used for?

They are used for preparing, processing, transporting, aliquoting, centrifuging, and storing small-volume laboratory samples. Typical workflows include molecular biology, microbiology, biotechnology, pharmaceutical research, clinical testing, and general laboratory use.

What sizes and bottom configurations are available?

The group includes 0.5 mL, 1.5 mL, and 2.0 mL self-standing tubes, plus a 1.5 mL conical-bottom tube.

How do I choose between the different tube sizes?

Choose 0.5 mL for limited-volume samples and small aliquots; 1.5 mL for routine sample preparation and centrifugation; and 2.0 mL when additional capacity is needed for lysates, microbial samples, buffers, or reagents.

What is the difference between self-standing and conical-bottom tubes?

Self-standing tubes remain upright on a laboratory bench, simplifying filling, labeling, and sample preparation. The conical-bottom tube directs material toward the narrow base, supporting pelleting and efficient recovery after centrifugation.

Are these tubes sterile?

Yes. All four tubes are supplied sterile.

Are the caps supplied attached to the tubes?

Yes. These products use attached hinged natural-color screw caps, helping keep the correct cap with each tube during handling and sample preparation.

What is the benefit of the hinged-cap design?

The hinge keeps the cap connected to the tube, reduces the chance of cap mix-ups or loss, and can make repeated opening and closing more convenient during bench work.

What is the benefit of an external thread?

An external thread keeps the threaded closure surface outside the tube's sample-contact area and provides additional working space near the opening.

What is the purpose of the sealing ring?

The sealing ring helps create a secure closure between the cap and tube, supporting sample handling, transport, processing, and storage.

Can these tubes be centrifuged?

They are designed as microcentrifuge tubes and are suitable for centrifugation workflows. Confirm that the selected rotor, adapter, temperature, and centrifugal force are compatible with the specific tube before use.

Which tube is best for sample pelleting?

SKU 634112-N, the 1.5 mL conical-bottom tube, is the preferred configuration because the base concentrates material into a smaller area for easier pellet location and recovery.

Can these tubes be used for DNA and RNA samples?

They are suitable for general handling and aliquoting of DNA, RNA, PCR reagents, primers, enzymes, and other molecular biology samples. Confirm application-specific purity and certification requirements before use.

Can these tubes be used for protein samples?

Yes. Typical applications include protein extraction, sample preparation, phase separation, reagent storage, and aliquoting. Confirm compatibility with the specific buffers, solvents, and processing conditions used.

Are these tubes suitable for frozen or cryogenic storage?

Suitability depends on temperature, storage duration, sample type, and laboratory protocol. Confirm the rated temperature range for the exact SKU before frozen or cryogenic use.

Can the tubes be autoclaved?

Do not autoclave unless autoclavability is confirmed in the technical specifications for the exact SKU. These products are supplied sterile, and additional processing may affect tube or closure performance.

Are these tubes compatible with standard microcentrifuge racks and rotors?

Compatibility depends on tube capacity, bottom configuration, and rack, rotor, or adapter dimensions. Verify the equipment manufacturer's requirements before centrifugation or automated processing.

What competitor products do these tubes cross-reference with?

The cross-reference table lists selected USA Scientific, Fisher Scientific, VWR, and Sarstedt catalog numbers. These numbers are comparison guides; verify specifications and equipment compatibility before substitution.

Are cross-referenced tubes guaranteed to be identical?

No. Cross-references identify generally comparable formats and intended applications, but materials, dimensions, certifications, packaging, and performance specifications may differ. Review the applicable technical documentation before substituting products.
