Product Description
LIGHT LABS is proud to offer the CELLTREAT 182cm² Deep Volume Tissue Culture Treated Flask with Vent Cap (Cat # 229381) — affectionately known as the "Weekend Flask" for its unique extra-depth design that allows cell cultures to grow for longer periods without drying out or depleting their nutrient supply. The 229381 is the deep volume variant of CELLTREAT's standard 182cm² TC-treated flask (229351) — sharing the same 182cm² footprint (which already provides more growth area than the industry-standard 175cm² flask) but with increased internal depth that accommodates significantly more media volume, enabling researchers to leave cultures unattended over weekends or extended periods without sacrificing cell viability or culture performance.
The tissue culture treated surface delivers a consistent, uniform hydrophilic surface optimized for maximum adherent cell attachment across the full 182cm² growth area — more surface area than the standard 175cm² flasks used by many competing brands. The large opening canted neck design with moderate angles provides easy access to the entire flask surface — particularly important when using cell scrapers for adherent cell harvesting. The stable flat base allows the flask to stand upright during filling, eliminating the need for a stand or holder when adding media. Molded interlocking T-design on compatible flask sizes enables secure, space-efficient stacking. The 0.22µm hydrophobic membrane vent cap maintains sterility by allowing gas exchange with the CO₂ incubator atmosphere while preventing microbial contamination. Every flask is printed with lot number and expiration date for quality traceability, and flasks are packaged in convenient zip-closure resealable bags — a practical alternative to folding and taping open bags. LIGHT LABS is your trusted source for CELLTREAT laboratory plasticware.
KEY FEATURES
- Deep Volume "Weekend Flask" design — extra internal depth accommodates significantly more media volume than standard 182cm² flasks; leave cultures to grow over the weekend without drying out or depleting nutrients
- 182cm² TC-treated growth area — more surface area than industry-standard 175cm² flasks; uniform hydrophilic surface for consistent, maximum adherent cell attachment
- Vent cap with 0.22µm hydrophobic membrane — allows CO₂/gas exchange with incubator atmosphere while maintaining sterility
- Large opening, canted neck design with moderate angles — easy access to entire flask surface; ideal for cell scrapers and pipettes
- Stable flat base — flask stands upright during filling without a stand or holder
- Thick, durable polystyrene walls for structural integrity and resistance to warping
- Molded interlocking T-design — compatible stacking with other CELLTREAT 75, 182, and 300cm² flasks and 250, 600, and 850mL flasks
- Convenient zip-closure resealable bag packaging — practical alternative to folding and taping open bags
- Every flask printed with lot number and expiration date for easy identification and quality traceability
- Sterile — gamma irradiated
- Certified nonpyrogenic and RNase-/DNase-free
- Packaged 5 flasks per resealable bag; 8 bags per case (40 flasks/case)
