In cell biology laboratories, cell culture flasks serve as the vital microenvironment for cellular growth. Combining excellent optical clarity with chemical stability, high-quality culture flasks are essential for maintaining reproducible, strain-free experimental outcomes.
Manufactured from medical-grade, USP Class VI Polystyrene (PS), A-Gen Cell Culture Flasks feature an ergonomic angled-neck design and frosted writing areas. They streamline fluid transfer, eliminate dead angles, and ensure seamless sample traceability across applications ranging from basic research to industrial scale-up.

01 Surface Modifications: TC-Treated vs. Non-TC Treated
TC-Treated Flasks (Adherent Culture):
A-Gen TC-treated flasks undergo specialized vacuum-plasma surface modification to introduce hydrophilic functional groups. This creates an optimal charged microenvironment that promotes uniform cell attachment, spreading, and proliferation.
Non-TC Treated Flasks (Suspension Culture):
Non-TC treated flasks retain the natural hydrophobic surface properties of polystyrene, effectively preventing cell attachment and making them ideal for suspension cells, hybridomas, and microbial cultures.

02 Cap Options: Plug Seal Caps vs. Vented Filter Caps
Linerless Plug Seal Caps (Closed Culture):
Featuring a precision single-piece molded design without inner liners, plug seal caps deliver a leak-proof seal to isolate cultures from external environments. Loosening the cap by a quarter-turn enables open gas exchange when needed.
Vented Filter Caps (Continuous Gas Exchange):
Equipped with a built-in 0.22 µm hydrophobic membrane, vented caps facilitate continuous, sterile gas exchange while forming an absolute barrier against microbial contaminants. They are strongly recommended for CO₂ incubators to maintain stable pH and culture conditions.

03 Key Engineering Highlights
Angled-Neck Architecture: The short, wide, angled-neck design allows easy pipette and cell scraper access to every corner of the flask, eliminating operational dead zones.
Stacking Stability: Rigid mechanical rim design on the top and bottom surfaces prevents slipping, allowing safe stacking and maximizing incubator space utilization.
Dual-Sided Volumetric Graduations: Clear printed horizontal and vertical scale lines on both sides provide accurate volume readings regardless of flask orientation.
Frosted Writing Areas: Prominent writing areas on the flask shoulder facilitate clear sample labeling and tracking.
04 Stringent Biocompatibility & Quality Standards
Sterility Assurance: Sterilized by Electron Beam Irradiation with a **Sterility Assurance Level (SAL) of 10⁻⁶**.
Certified Purity: Non-pyrogenic, endotoxin-free, DNase/RNase-free, and non-cytotoxic.
Class 100,000 Cleanroom Manufacturing: Produced in automated, dust-free facilities to ensure strict batch-to-batch consistency and optical transparency.
05 Versatile Capacities for Scale-Up
A-Gen Cell Culture Flasks are available in four standard growth areas:
25 cm², 75 cm², 175 cm², and 225 cm².
Whether cultivating primary cells, stem cells, mammalian lines, or tissue-engineered constructs, A-Gen provides reliable, contamination-free consumable solutions tailored to your laboratory requirements.
