Culture Tubes 14mL Dual Cap – Lichen Cottage Labware, 100 Pack

Description

Product Overview

The 14 mL Culture Tubes from Lichen Cottage are purpose‑built for modern laboratory environments where precision, durability, and versatility are essential. Each tube is fabricated from high‑grade polypropylene (PP) that has undergone gamma irradiation, ensuring a sterile, contaminant‑free surface right out of the package. The tubes measure 17 × 9.3 mm, providing a compact footprint while delivering a standard 14 mL capacity that fits seamlessly into most incubators, racks, and centrifuge rotors. A standout feature is the dual‑position cap: when unscrewed, the cap opens a breathable channel for aerobic cultures; when fully tightened, it creates an airtight seal suitable for anaerobic work. This design eliminates the need for separate tube types, streamlining workflow and reducing inventory complexity. The body tolerates autoclave temperatures up to 121 °C and can withstand centrifugal forces up to 3000 rcf, making it ideal for sterilization and high‑speed centrifugation. A machine‑die‑engraved scale runs along the side of each tube, offering a clear, permanent measurement reference that resists fading or abrasion. Additionally, a dedicated writing area on the tube surface allows researchers to label samples directly, minimizing the risk of misidentification. Packaged in a sturdy case of 100 tubes, the product dimensions are 13 × 8.8 × 3.2 inches, weighing just 1.2 lb, which simplifies storage and shipping.

Usage

These culture tubes are suited for a broad spectrum of applications across microbiology, cell culture, biotechnology, and environmental testing. In microbiology labs, the dual‑position cap enables seamless transition between aerobic and anaerobic incubation, supporting the growth of a wide range of bacterial and fungal species. The gamma‑irradiated PP material ensures that the tubes are free from endotoxins and other contaminants, a critical requirement for sterile culture work. For cell culture, the clear, chemically inert surface does not interact with media components, preserving cell viability and experimental integrity. The tubes also perform reliably under autoclave sterilization, allowing labs to reuse them safely after proper cleaning. In analytical chemistry, the engraved scale provides an accurate visual reference for liquid volumes, reducing the need for additional measuring devices. The robust construction tolerates high‑speed centrifugation, making the tubes ideal for pellet formation, phase separation, and sample concentration steps. Whether used in academic research, pharmaceutical development, or quality‑control laboratories, these tubes meet the rigorous demands of modern scientific protocols.

FAQ

Can these tubes be used for both aerobic and anaerobic cultures?

Yes. The dual‑position cap is designed to provide a breathable environment when unscrewed for aerobic work and an airtight seal when fully tightened for anaerobic conditions.

Are the tubes compatible with standard laboratory racks and centrifuges?

Absolutely. With a 17 × 9.3 mm footprint, the tubes fit standard micro‑centrifuge rotors, incubator racks, and storage trays commonly used in research labs.

What sterilization methods are recommended?

The tubes are gamma‑irradiated for sterility out of the box and can be autoclaved at 121 °C for up to 30 minutes without compromising structural integrity.

How does the engraved scale differ from printed markings?

Machine‑die‑engraving creates a permanent, abrasion‑resistant scale that remains clear even after repeated cleaning, unlike printed markings that can fade or wear off.

What is the warranty or return policy?

Lichen Cottage offers a 30‑day satisfaction guarantee; if the product does not meet your expectations, contact our support team for a replacement or refund.
