Spinner Flask Accessories



Product Line


Single-use technologies are playing a key role in the reduction in risk of cross contamination in addition to time and cost benefits associated with assembly, cleaning and cleaning validation. Bio-Simplex™ Spinner Flask Accessories are designed to allow user to maintain their current investment in glassware, but with the convenience of a single-use filling assembly. Molded one piece construction creates a seamless fluid path and unobstructed inner bore, eliminates contamination and product loss due to loose connections. The assembly includes:

1.) an EZ Top® stopper, made from C-FLex® pharmaceutical grade animal derived component free (ADCF) thermoplastic elastomer (TPE) resin and tubing to insure an unobstructed fluid path, extremely low levels of extractables and provide an elastomeric seal against glass, plastic and metal surfaces.

2.) a Bio-Simplex™ FlexJoint™ which uses a patent-pending design and construction to accommodate angle deviation in hand blown spinner flasks and eliminate tube kinking and shape loss after autoclaving.

3.) a polypropylene cap. Bio-Simplex™ Spinner Flask Accessories are easily used with sterile connecting devices and thermal tubing sealers.

We offer standard 2 and 3 port configurations in 1, 3, 8, 15 and 36 Liter sizes, sold as single items. All are autoclavable.

Customer-generated designs, sizes, packaging and other options –– such as connectors, heat-sealed ends or alternate materials –– are available as custom orders.
