Cell Culture Tubes Alkali Scientific PP 12×75mm Sterile Dual Plug Caps

Description

Product Overview

Alkali Scientific delivers a premium line of cell culture tubes crafted from high‑grade polypropylene, a material renowned for its chemical resistance, durability, and clarity. Each tube measures 12 × 75 mm, a standard size that fits seamlessly into most incubators, centrifuges, and rack systems used in modern laboratories. The tubes are rigorously sterilized to guarantee a completely RNase‑, DNase‑, pyrogen‑, and cytotoxin‑free environment, eliminating any risk of contaminating sensitive cell cultures. Dual‑position plug caps are engineered with a precision‑molded seal that locks securely in both upright and inverted positions, providing a leak‑proof barrier against evaporation and cross‑contamination during prolonged incubations or vigorous shaking. The product is supplied in bulk packs of 25 bags, each containing 1,000 tubes, ensuring a reliable inventory for high‑throughput applications while reducing per‑unit cost.

Usage

These culture tubes are ideal for a broad spectrum of cell‑based assays, including adherent and suspension cultures, stem cell maintenance, and microbial fermentation studies. Researchers can employ the tubes for routine media exchanges, sub‑culturing, and sample storage, benefiting from the sterile barrier that protects against external contaminants. The dual‑position caps allow users to invert tubes without risking spillage, a feature especially valuable during centrifugation steps or when performing gradient separations. Compatibility with standard laboratory equipment such as vortex mixers, plate readers, and automated liquid handling systems ensures seamless integration into existing workflows, while the clear polypropylene body facilitates easy visual inspection of cell density and morphology without the need for additional staining or microscopy.

Why Choose Us

Alkali Scientific stands out for its commitment to quality assurance and rigorous testing protocols. Every batch of culture tubes undergoes a multi‑stage validation process that includes endotoxin testing, nucleic acid contamination checks, and mechanical integrity assessments to confirm cap performance under repeated opening and closing cycles.

FAQ

Are the tubes pre‑sterilized?

Yes, each tube is gamma‑irradiated and sealed in a sterile environment to guarantee RNase‑, DNase‑, pyrogen‑, and cytotoxin‑free conditions straight out of the package.

Can the tubes be autoclaved?

The polypropylene material tolerates standard autoclave cycles (121 °C for 30 minutes) without deformation, allowing users to re‑sterilize if needed.

What is the maximum volume the tube can hold?

The 12 × 75 mm tube is rated for up to 2 mL of liquid, providing ample capacity for most cell culture and assay applications.

Are the caps compatible with other brands?

The dual‑position caps are designed to fit the standard 12 × 75 mm tube neck dimensions used across major laboratory brands, ensuring cross‑compatibility.

How should the tubes be stored?

Store the tubes in a cool, dry place away from direct sunlight. The sealed bags protect against moisture and maintain sterility until the point of use.
