The subject invention is a clamp that has two halves of an annular ring hingedly connected at one end and capable of being securely fastened to each other at the opposite end. The annular ring is sized to fit tightly around a vertical support post. An upper surface of the annular ring has an upper annular channel, while the lower surface of the annular ring has a lower annular channel. When the clamp is fixed to the vertical support post, a horizontal support adaptor may fit into both the upper and lower annular channels. A resilient engagement strip or button on the adaptor is placed into contact with the lower annular channel in this position and frictionally engages the lower annular channel to prevent lateral movement of the adaptor on the annular ring until such time as the adaptor may be securely attached to the annular ring.

A stirring hot plate for simultaneously heating and stirring a mixture includes a phase controlled motor that spins magnets which couple to, and thereby spin, a stir bar within the mixture. In addition to spinning the magnets, the motor includes an operational mode in which the motor is rapidly braked thereby quickly spinning down the stir bar. The stirring hot plate also includes a visual indicator to the user that the platform is hot-to-the-touch that is especially effective when the stirring hot plate is not in use.

A water purification system for purifying water flowing through a water flow path. The system includes a water purification device having an inlet and an outlet in the water flow path and at least one interior volume communicating with the inlet and outlet. A purification medium is disposed within the interior volume of the water purification device. A flow control system is provided controlling a volume of purified water dispensed from the outlet. The flow control system includes an input device configured to allow a user to input a desired volume of purified water to be dispensed from the outlet and a sensing device coupled with the electronic input device and operative to determine the volume of purified water being dispensed from the outlet. A flow regulation device is coupled with the flow control system and operative to stop the discharge of purified water at the outlet upon reaching the desired volume of purified water.

A filter assembly for a water purifying apparatus including a plurality of cartridges. Each cartridge includes first and second ends and an interior volume containing a filtering medium. A plurality of end caps are respectively connected with the first ends of the plurality of cartridges and each end cap includes a water inlet and a water outlet. A removable manifold is coupled with the water inlets and water outlets and the manifold includes a pair of auxiliary ports. One auxiliary port directs water from the cartridge assembly to an auxiliary processing device and another auxiliary port directs the water from the auxiliary processing device back to the filter assembly. The water inlets and water outlets extend generally parallel to a longitudinal axis of each cartridge. The cartridge includes an outer tubular member in fluid communication with the water inlet and an inner tubular member in fluid communication with the water outlet. The inner tubular member has a first end connected in a sliding manner to the first end cap and a second end rigidly affixed to the second end cap.

A sterilizer valve including a valve body with an inlet, an outlet, a vent, and a centerbore intersecting the inlet, outlet and vent. The valve further includes a valve stem having a shot chamber for holding a volume of sterilizing fluid, a fill passage having one end in fluid communication with the shot chamber and a second end intersecting the exterior surface at a fill port. The valve stem also has fluid communicating paths extending through the interior and disposed in an external surface of the valve stem. The valve stem is rotatably disposed in the centerbore of the valve body to selectively fluidly connect the shot chamber with the vent through the fluid communication paths upon the valve stem having different rotational positions with respect to the valve body.

A manually operable fluid dispensing system having a fluid dispenser connected to a fluid source by flexible tubing. The dispensing system provides a supply fluid path from the source of fluid to the dispenser and a recirculation fluid path from the dispenser to the source of fluid. A dispenser mount is rigidly attached to a support surface for releasably holding the dispenser, and the dispenser mount supports the dispenser in a fixed position for dispensing fluid therefrom. In addition, the dispenser can be removed from the mount for dispensing fluid at a remote location. A manually operable trigger is pivotally connected to the dispensing valve and has a quiescent position which closes the dispensing valve. When in the quiescent position, a trigger handle extends over an exterior portion of the dispenser body in a generally forward direction toward the dispensing outlet and forms an included angle with the dispenser body. The trigger is movable toward the dispenser body to open the dispensing valve, thereby permitting fluid to flow through the dispensing outlet. A spring biases the trigger handle toward its quiescent position, thereby closing the dispensing valve and stopping the flow of fluid through the dispensing outlet.
