Cell Culture Flasks
Sigma Aldrich Fine Chemicals Biosciences PureColTM Coated T25 flask
Collagen is the main structural protein of the extracellular matrix found within various connective tissues of the body. Type I collagen is a major structural component of skin bone tendon and other fibrous connective tissues. In order to provide the most in vivo-like environment for cells researchers have historically cultured cells inside collagen hydrogels or on top of collagen coated plasticware. PureCol is an ultrapure bovine skin derived collagen that is approximately 97% Type I collagen with the remainder being comprised of Type III collagen. It contains a high monomer content as measured by gel permeation chromatography providing product consistency reproducibility and is cited in over 2000 publications. PureCol Coated T25 flasks have a uniform and consistent application of high quality Type I collagen on clear polystyrene surface. The vented flasks have an anti-drip edge and modified canted neck to provide maximum control replacing nutrient depleted media. The flasks have
Thomson Instrument Company Ultra Yield 2.5L Flask, Sterile
Ultra Yield Flasks are sterile, single-use shake flasks engineered for max oxygen transfer and high-density growth. Their high-aeration geometry, used on standard orbital shakers, drives faster cultures and cleaner downstreams. Pair with AirOtop Enhanced Seals or Vented Screw Caps; with Plasmid+ Media, customers have reported plasmid yields up to 610%.Key features
•High-aeration geometry/baffled base to boost OTR and mixing
•Sterile, ready-to-use single-use format for low contamination risk
•Sizes from 125 mL to 2.5 L for bench-to-pilot scalability
•Engineered for high-rpm orbital shaking (stable, leak-tight operation)
•Closure flexibility: AirOtop seals, Vented Screw Caps, or Bidirectional Transfer Caps
•Clear graduations & label area for easy sampling and tracking
•Made in the USA with reliable, fast shipment

Chemglass Life Sciences Flask, Shake, 500mL, 6 Baffles, Delong Neck, Approx OD x Height (mm): 100 x 200
Flask, Shake, 500mL, 6 Baffles, Delong Neck, Approx OD x Height (mm): 100 x 200. Flask has 6 baffles, 3 baffles on the lower outside edge of the flask and 3 baffles on the bottom surface of the flask to maximize oxygen transfer to the culture medium when used on an orbital shaker. Delong style neck is made to fit stainless steel or plastic closures, while the longer neck reduces the amount of splashing that would reach the closure.
Chemglass Life Sciences Flask, Shake, 2L, 6 Bottom Baffles, 70mm Vented Cap, Approx OD x Height (mm): 170 x 270
Flask, Shake, 2L, 6 Bottom Baffles, 70mm Vented Cap, Approx OD x Height (mm): 170 x 270. Flask has 6 bottom baffles to maximize oxygen transfer for bacterial, yeast and other cultures that require large amounts of oxygen for optimal growth. The 70mm vented cap has a 0.20µm PVDF hydrophobic membrane to allow for sterile gas exchange while preventing contamination. A silicone liner ensures a tight seal between the cap and flask. The flasks, cap and liners are all fully autoclavable.
Thomson Instrument Company Optimum Growth 125mL Flask, w/ Sampling Port and Vent Cap, Sterile
