Product Description
LIGHT LABS is proud to offer the CELLTREAT 12.5cm² Tissue Culture Treated Flask with Vent Cap (Cat # 229321) — a premium, sterile, TC-treated tissue culture flask ideally suited for small-scale cell culture, primary cell isolation, initial culture establishment, and applications where minimal media volume and cell numbers are required. The 12.5cm² format is the smallest standard tissue culture flask in CELLTREAT's comprehensive flask line — making it the preferred choice for establishing new cell lines from limited starting material, maintaining precious primary cell cultures at minimal scale, or running small-scale experiments where larger flask formats would be wasteful.
The tissue culture treated surface delivers a consistent, uniform hydrophilic surface optimized for maximum adherent cell attachment and spreading — ensuring reliable, reproducible culture performance. The large opening canted neck design with moderate angles provides easy access to the entire flask surface — important when using pipettes or cell scrapers in a small flask format. The stable flat base allows the flask to stand upright during filling, eliminating the need for a stand. The green HDPE vent cap with 0.22µm hydrophobic membrane allows consistent gas exchange with the CO₂ incubator atmosphere while maintaining sterility. Every flask is printed with lot number and expiration date for quality traceability, and flasks are packaged in convenient zip-closure resealable bags. LIGHT LABS is your trusted source for CELLTREAT laboratory plasticware.
