A clamp means is provided for holding at least one vessel so that the vessel can be agitated by a drive means with the clamping means permitting the vessel to move with the clamping means defining the null point of the movement. The clamp means may provide a rack for resiliently clamping the vessel. Preferably, the clamping means is for resiliently clamping the vessel at a position remote from the bottom thereof. Drive means are provided for imparting motion, such as orbital motion, to the agitating means whereby fluent contents of the vessel are agitated. The apparatus is adapted for the holding and agitating a single or a plurality of vessels, such as a plurality of test tubes. The drive means also is capable of pulsing the orbital motion.

A clamp for holding a vessel while the bottom of said vessel is subjected to an orbital movement, to spin liquid contained within said vessel, said apparatus comprising a support member engaging the vessel at an upper portion thereof, said support member comprising a resilient collar comprising a rubbery material to frictionally engage and hold said vessel in said collar while the bottom of said vessel receives said orbital movement, said rubbery material of said resilient collar frictionally engaging said vessel and comprising yieldable characteristics permitting the bottom of the vessel to receive an orbital movement while said vessel is held within said resilient collar, said liquid being spun under influence of said orbital movement, said support member and said vessel being arranged to define a null point of movement of said vessel to be centered within the region defined by said resilient collar to prevent spillage of the liquid contained in the vessel while being spun during said orbital movement.
