Pre-Mixing Setup
The mixing biocontainer must be assembled properly prior to mixing. The following components are needed to
assemble the biocontainer:
▪
Stainless steel rotational wand.
▪
Stainless steel coupler
–
The coupler provides mechanical interface between the biocontainer and the
driving motor. It has a hollow bore that receives the sleeve fitting on the biocontainer. The coupler is
secured on the sleeve fitting of the biocontainer with two thumb screws. It has a flanged end that mates
with the flange of the shaft adaptor.
▪
Plastic bushing
–
The plastic wand bushing centres the wand in the sleeve fitting. The wand is inserted into
the bushing prior to wand insertion into the biocontainer.
▪
Shaft adaptor
–
The shaft adaptor interfaces the coupler and the driving motor. The adaptor receives the
hexagonal head of rotational wand. The bearing in the flange of the shaft adaptor decouples the rotation of
the shaft from the biocontainer.
▪
Clamp
–
The clamp secures the connection between the mating flanges of coupler and shaft adaptor.
Properly assembling the biocontainer starts by placing the mixing biocontainer into appropriate retaining tank
and filling it with fluid by using the appropriate tube line. Make sure that retaining tank is compatible with the
biocontainer volume. Next, ensure the two thumb screws do not penetrate beyond the inner surface of the
coupler. Assemble the coupler with the biocontainer by sliding the coupler over the sleeve fitting all the way down
to the film of the biocontainer as shown on the next page in Step 2 of 7. Secure the coupler against the fitting by
tightening both thumb screws. The wand part number is stamped on its hexagonal head. Use only the specified
wand.Insert the rotational wand into the bushing, and then insert the assembly into the sleeve of the biocontainer
as shown in Step 3 of 7.
