Polypropylene Culture Tube Globe Scientific 110178 14mL Sterile Cap

Description

Product Overview

The Globe Scientific 110178 polypropylene culture tube is engineered for demanding laboratory environments where reliability, sterility, and versatility are paramount. Constructed from high‑quality polypropylene, each tube measures 17 mm in diameter and 100 mm in height, providing a 14 mL capacity that accommodates a wide range of sample volumes. The material offers excellent chemical resistance, ensuring that the tube does not interact with common reagents, buffers, or media. A key feature is the LDPE dual‑position cap, which can be left loosely fitted for aerobic cultures that require gas exchange, or snapped tightly for anaerobic conditions where a sealed environment is essential. This flexibility eliminates the need for multiple tube types, streamlining inventory and reducing costs. The tubes are autoclavable, allowing for standard steam sterilization cycles without deformation, and they are also freezable, making them suitable for long‑term storage at sub‑zero temperatures. Designed to endure centrifugation speeds up to 3000 RPM, the tubes maintain structural integrity during high‑speed processing, preventing sample loss or contamination. Each tube is supplied sterile, packaged in groups of 25 within a sealed bag, and 20 such bags are assembled into a case of 500, ensuring that laboratories can meet the demands of high‑volume workflows with confidence.

Usage

These culture tubes are ideal for a broad spectrum of applications across microbiology, cell culture, molecular biology, and biochemical assay laboratories. In microbiology, the dual‑position cap enables researchers to cultivate aerobic bacteria while still providing the option to seal the tube for anaerobic strains, supporting studies ranging from environmental sampling to clinical diagnostics. Cell culture practitioners benefit from the tube’s chemical inertness and temperature resilience, allowing for the preparation of media, sub‑culturing, and cryopreservation of cell lines. The high centrifugation tolerance makes the tubes suitable for pellet formation, supernatant removal, and sample concentration steps in protocols such as plasmid purification, protein precipitation, and nucleic acid extraction. Because the tubes are autoclavable, they can be re‑sterilized after use, which is advantageous for labs that prioritize sustainability and cost‑effectiveness. The sterile packaging ensures that each tube is ready for immediate use, reducing the risk of contamination during critical experimental phases. Whether employed in routine quality control testing, research and development projects, or large‑scale production environments, these tubes provide a dependable platform for accurate and reproducible results.

FAQ

What temperature ranges can the tubes withstand?

The tubes are rated for standard autoclave cycles (121°C for 15‑30 minutes) and can be stored at temperatures as low as -80°C without cracking or loss of integrity, making them suitable for both sterilization and cryogenic storage.

Can the dual‑position cap be used with standard tube racks?

Yes, the cap’s dimensions are compatible with common laboratory tube racks and centrifuge adapters. The cap’s low‑profile design allows the tube to sit securely in racks while still providing the option to loosen the cap for gas exchange when needed.

Is the polypropylene material free of leachables that could interfere with sensitive assays?

Globe Scientific uses a low‑extractables polypropylene grade that has been tested for minimal leaching. This ensures that background signals in assays such as ELISA, PCR, or mass spectrometry are not compromised by tube material contaminants.

How many tubes are included in a case and how are they packaged?

Each case contains 500 tubes, organized into 20 sterile bags with 25 tubes per bag. The bags are sealed to maintain sterility until opened, providing a convenient and hygienic solution for high‑throughput laboratory environments.

What support does Globe Scientific offer if I encounter issues with the product?

Our dedicated technical support team is available via phone and email to address any product‑related questions, provide troubleshooting guidance, and assist with protocol development. We also offer on‑site training and documentation to help you get the most out of our culture tubes.
