All are made of USP Class VI and ISO 10993-18 compliant materials. Recommended working range of 1L to 3L. Extended paddle design ensures constant top-to-bottom motion of the liquid without having to adjust the height of the paddle.

Bottom contours on the paddle hug the shape of the flask, eliminating dead spots. Two wide neck openings for easy pouring; easily accept a 100 mL pipet. Vertical side baffles break up laminar flow - ensures better mixing and maximizes cell production. Each system is supplied individually double bagged. Sterilized by gamma irradiation; have the highest Sterility Assurance Level (SAL) of 10^-6 and meets USP XXIV:71 Bacteriostasis, Fungistasis and Sterility Standards.
