Ribbed surface roller bottles come in long and short forms, and are made of high grade polystrene for stability and optical clarity, with physical surface treatment for improved cell adhesion.

• Ribbed surface
• High-grade polystyrene construction
• HDPE screw cap construction with either standard seal or vented filter
• Free of RNase, DNase, and human DNA
• Non-cytotoxic (EN ISO 10993) and non-pyrogenic

Two-phase blow-molding procedure creates seamless construction so that liquids will not leak.

Screw caps are high-density polyethylene and come in standard seal (non-vented) or vented filter. Caps feature short threads and large knurls for improved grip and easy opening with a 2/3 turn. Standard seal cap sits flush with rim of bottle to prevent significant gas exchange. Vented filter cap guarantees tightly closed, contamination-free cultivation. Polyethylene terephthalate (PET) and polytetrafluorethane (PTFE) filter has hydrophobic capillary pore membrane, with defined pore size 0.2 µm. Filter provides optimal protection against contamination and a high gaseous exchange rate which enables mass cultivation of cells using biocarbonate buffer and CO₂.

Colors: clear roller bottle with black graduation print and white writing area, blue cap, white filter. Sterilized by irradiation (SAL 10⁻³) and tissue culture treated.

For single use only; lot number and best-before dates located on label for maximum traceability.
