portable dolly or a floor-mounted tank. Once properly charged and coupled
with the mixing bag, the activation of the motor induces levitation and rota-
tion of the in-bag impeller resulting in effective mixing action inside a her-
metically sealed bag. Coupling of the in-bag impeller with the drive motor
requires no dynamic seals or shaft penetration inside the bag. The drive
motor is enclosed on a portable cart that can be easily disconnected from
the bag and reconnected to another mixing bag, allowing mixing in multiple
bags of various sizes with a single drive unit. As with all ATMI LifeSciences'
single-use mixing systems, the LevMixer utilizes disposable mixing bags
made from Integrity TK8 bioprocess film. The product-contacting layer of
TK8 film is blow-extruded in-house by ATMI under cleanroom conditions
using medical-grade ultra-low-density polyethylene resin. It is then lami-
nated to create a gas barrier film of exceptional cleanliness, strength, and
clarity that is animal-derived component free (ADCF) and complies fully
with USP Class VI requirements.
