25cm² Rectangular angled Neck Cell Culture Flask

Enhance cell attachment, growth, and consistency with Pipettra 25cm² Cell Culture Treated Flasks. Designed for smaller-scale cultures, these high-grade polystyrene flasks undergo advanced plasma surface treatment to support optimal adhesion across a range of cell types. The angled neck and wide opening allow easy access for pipettes or scrapers ideal for efficient handling in compact incubator spaces.

Design & Performance Specifications:

• Plasma-modified to ensure consistent hydrophilicity and surface chemistry conducive to cell adhesion and uniform growth.
• Angled neck with a wide access port facilitates efficient pipetting and scraping, minimizing contamination risk and mechanical stress on cells.
• Enables efficient use of incubator space and allows for streamlined stacking.
• Graduations are both printed and molded on opposing flask walls for easy visual reference during media handling.
• Slightly tapered sidewalls reduce distortion, improving compatibility with phase-contrast and inverted microscopy.
• Each flask is sterilized by gamma irradiation and certified to be nonpyrogenic and free of detectable RNase, DNase, and human DNA.

Cap Options:

Filtered Vent Caps

• Incorporate a chemically resistant, hydrophobic membrane filter designed for continuous gas exchange while maintaining a sterile barrier against airborne contaminants.
• Membrane specifications meet USP Class VI requirements and are produced without animal-derived materials, ensuring suitability for sensitive or regulated workflows.
• Consistent airflow and filtration performance eliminate variability between batches.

Solid (Non-Vent) Caps

• Integrated with a molded “Y” directional indicator to identify venting orientation at a glance.
• Any arm of the “Y” aligned vertically confirms an open (vented) position, aiding identification even when multiple flasks are stacked.
• Designed for secure, leak-resistant closure and controlled gas exchange when manually adjusted.

Quality Assurance

Each lot is validated for surface quality and performance using representative adherent cell lines, with certification documentation included to support traceability and compliance in regulated environments.
