Guide and selection support

Screw cap microtubes are widely used in laboratories for sample storage and preparation, especially where secure sealing and reliable protection against leakage or contamination are essential. They are common in molecular biology, microbiology, and diagnostic labs.

Key selection factors include volume, material compatibility, seal integrity, and temperature resistance, especially for workflows involving deep freezing. Compatibility with centrifuges and automation systems may also be relevant.

LabFinder guides you through important selection criteria, available variants, and areas of application, supporting efficient navigation through a broad range of micro reaction tubes and cryostorage consumables.

Use and benefits

Screw cap microtubes are small sample vessels designed for the secure storage, transport, and handling of biological or chemical samples in laboratory environments. The screw cap effectively protects contents from leakage, contamination, and evaporation. Typical uses include molecular biology, microbiology, diagnostics, and cryostorage applications.

Selection criteria

Key factors include volume (commonly 0.2 to 2 ml), material properties (such as polypropylene and its chemical compatibility), and seal integrity. Suitability for centrifugation and integration with automation workflows can also be important. For ultra-low temperature uses, ensure compatibility with cryostorage.

Variants and measurement principles

Screw cap microtubes are available as individual tubes or in sets, varying in volume, tube geometry (round or conical), color-coded caps, and additional features such as labeling areas or automation readiness. There is no measurement principle as such, as the focus is on storage and transport.

Quality, storage and handling

Generally single-use, these tubes are molded from high-grade plastics designed for durability and resistance to temperature fluctuations. Screw caps provide reliable sealing for routine lab use. It is recommended to check seal integrity before use, especially prior to storage or centrifugation.

Application limits

Screw cap microtubes are not suited to high-pressure applications or exposure to highly aggressive chemicals. For high-speed centrifugation, specialized centrifuge tubes should be used. Long-term storage under extreme conditions may cause material fatigue or wear on the cap mechanism.

Frequently asked questions

How are screw cap microtubes used in routine lab applications?

They serve as small sample containers with a secure screw cap, preventing liquid leaks and minimizing the risk of sample contamination.

What variations of screw cap microtubes exist?

These tubes are available in various volumes (usually 0.2 to 2 ml), materials, and shapes. Options may feature colored caps, labeling areas, or compatibility with laboratory automation.

What should I consider when selecting screw cap microtubes?

Consider factors such as volume, material resistance, seal effectiveness, centrifuge compatibility, and suitability for cryostorage if needed.

Can I use screw cap microtubes for cryopreservation?

Yes, many are suitable for deep-freeze storage, provided they are specifically designed and tested for such conditions.

What are the limitations of screw cap microtubes?

They are not intended for very high centrifugation speeds or strongly reactive chemicals, and may be less suited for long-term storage in extreme environments due to potential material and closure wear.
