Globe Scientific Culture Tube 5mL 12x75mm Polystyrene Snap Cap Sterile

Description

Product Overview

The Globe Scientific Culture Tube is engineered for modern laboratory environments where precision, reliability, and efficiency are paramount. Constructed from high‑quality clear polystyrene, each 5 mL tube provides exceptional optical clarity, allowing researchers to monitor microbial growth, precipitation, and color changes without interference. The tube dimensions of 12 mm diameter by 75 mm length conform to standard laboratory equipment, ensuring compatibility with incubators, shakers, and centrifuges.

One of the standout features is the attached dual‑position snap cap made from low‑density polyethylene (LDPE). The cap can be left loosely positioned to permit gas exchange for aerobic cultures, or fully sealed to create an anaerobic environment, giving scientists the flexibility to conduct a wide range of microbiological and biochemical assays. Each tube is pre‑sterilized, eliminating the need for additional autoclaving steps and reducing the risk of contamination.

Designed for high‑throughput workflows, the tubes are packaged in convenient bulk quantities: 25 tubes per resealable bag and 20 bags per case, totaling 500 sterile tubes per case. This packaging strategy minimizes handling time, reduces inventory clutter, and supports laboratories that process large sample volumes daily.

Usage

The Globe Scientific Culture Tube is suitable for a broad spectrum of applications across microbiology, biotechnology, environmental testing, and clinical diagnostics. Researchers can employ the tubes for routine bacterial culture, fungal growth studies, enzyme assays, and small‑scale fermentation processes. The clear polystyrene body enables direct visual assessment of turbidity, colony morphology, and pigment production, which is essential for rapid decision‑making in experimental protocols.

In addition to standard incubation, the tubes are centrifugation‑ready, tolerating speeds up to 1500 RPM without compromising structural integrity. This makes them ideal for pellet formation, cell harvesting, and sample clarification steps. The dual‑position cap design also supports anaerobic chambers and gas‑controlled incubators, allowing seamless transition between aerobic and anaerobic conditions within the same workflow.</n

Laboratories that require strict sterility, such as pharmaceutical development, food safety testing, and clinical microbiology, will benefit from the pre‑sterilized nature of each tube. The bulk packaging reduces the frequency of restocking, ensuring that critical experiments are not delayed due to supply shortages.
