Patent ID: 7517136

Claim:
A device for clamping a container in a mixer for fluids, comprising at least one clamping unit selectively operable for clamping, in use, at least one container by the application of compressive forces, and sensor means associated with said clamping unit for detecting the application of a predetermined clamping force to said container, wherein said clamping unit comprises one or more resilient compression members adapted, in use, to exert a compressive force, wherein said sensor means is able to detect the deflection of said one or more resilient compression members to reach a predetermined position, the deflection determining said predetermined clamping force, since the deflection of the resilient compression members is proportional to clamping force wherein said claimping unit further comprises at least two opposed clamping plates movable with respect to one another for clamping said container, and wherein one of said two clamping plates is resiliently connected to a transverse member by the insertion of at least one of said resilient compression members wherein said sensor means comprise at least one sensor for detecting said predetermined position of said clamping plate to said transverse member.
