A thermal immersion circulator can comprise a heater including a hollow cylindrical main body having an inlet opening at a first end thereof and an outlet opening in a side wall thereof. The heater can include a flexible circuit board having a plurality of resistive bands controlled by controlling electronics such as TRIACs, which can be water-cooled. A thermal immersion circulator including such a heater can be used in scientific laboratories or sous vide food cooking.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment. A first rotational assembly includes a first casing mounted to the first end of the flexible bag and a first hub rotatably mounted to the first casing. A second rotational assembly includes a second casing mounted to the second end of the flexible bag and a second hub rotatably mounted to the second casing. A connector has a first end coupled with the first hub and an opposing second end coupled with the second hub, the connector being flexible and having a uniform flexibility along its entire length. A first impeller is mounted to the connector.

A method for mixing a biological suspension includes disposing a biological suspension within a compartment of a container, the biological suspension comprising cells or microorganisms suspended within a nutrient growth medium; and rotating a first drive line and laterally spaced apart second drive line within the compartment of the container so as to cause the drive lines to twist into a helical configuration and mix the biological suspension.

A mount for a water circulator is described that is configured to control vertical adjustment and angular (or horizontal) adjustment of a water circulation assembly using independent mechanisms on the mount that mounts the water circulator to a support structure.

The present invention relates to a disposable container (100) comprising a side wall (2, 32), top (4) and bottom (6), wherein the side wall (2; 32) and the bottom (6) comprise a flexible material, wherein the side wall (2; 32), top (4) and bottom (6) are joined together to define the container (100) with an interior compartment (10) for keeping a fluid inside the container (100). The bottom (6) of the container (100) comprises at least one portion of rigid or semi-rigid material comprising a folding means (124; 224; 324; 324) that enables folding of the bottom (6). Thus an easy way of folding the bottom of the container is provided.

A pot lid assembly comprises a pot lid, an electric motor assembly and a mixing apparatus. The electric motor assembly is fixed to the pot lid. The mixing apparatus includes a stirring rod and a plurality of stirring vanes. The electric motor assembly includes an electric motor. The electric motor includes a rotary shaft operatively connected with the stirring rod so that the electric motor can cause the stirring rod to rotate. The pot lid is configured to cover the pot body to form a closed cooking space. When the pot lid is removed from the pot body, the rotary shaft is disengaged from the stirring rod, and the mixing apparatus can stand in the cooking space of the pot body, with the stirring vanes serving as a support. The mixing apparatus remains in the cooking space of the pot body after the removal of the pot lid.

The present disclosure relates to a mixing assembly for a fluid mixing system. The mixing assembly includes a first rotational assembly having a first casing and a first hub rotatably mounted to the first casing, a second rotational assembly having a second casing and a second hub rotatably mounted to the second casing, an elongated member having a first end coupled with the first hub and an opposing second end coupled with the second hub, and one or more impellers secured to the elongated member.
