A pipette gun and holster apparatus having a remote source of positive and negative air pressure. The holster supports the pipette gun above a work table with the pipette connector oriented generally, vertically downwardly. The holster has a base which may be fastened to a vertical wall. A mounting bracket is fixed to and extends transverse to the base. The bracket has a bottomless socket constructed and arranged to receive and removably hold the pipette gun by inserting the pipette connector into the socket. A switch deactivates the remote air pressure source when the pipette gun is parked in the holster and energizes the remote air pressure source when the pipette gun is removed from the holster. A method of metering fluid using a pipette gun and holster apparatus. The holster is removable fastened to a vertical surface next to or proximate a horizontal work table top.

A diaphragm pump with a bi-component diaphragm pump housing. The housing has a top component and a bottom component that connect along first and second complimenting connection interfaces and form an interior pump chamber, an exterior pressure port, an exterior vacuum port, and fluid communication channels connecting the exterior ports with the interior chamber. The first and second connection interfaces are oriented transverse to one another. The components of the pump are self-locking and can be assembled without the use of tools.

A device for dispensing a rolled web of material having a plurality of laterally-extending, longitudinally-spaced lines of perforation. The device has a frame for supporting the rolled web such that lengths of the web are removed from the roll in a direction of advancement as the roll rotates. An infeed roller pair is rotatably mounted on the frame. The infeed roller pair provides a nip therebetween for receiving the web from the roll and for moving it forward in the direction of advancement. A pair of delivery rollers is rotatably mounted on the frame in spaced relation with the first pair of rollers. The second pair of rollers receives the web from the first roller pair and provides a nip therebetween for moving the web in the direction of advancement. Motor means drives the infeed roller pair and the delivery roller pair. Brake means is affixed to the infeed roller pair for slowing the rotational speed thereof relative to the delivery roller pair whereby sufficient tension is created in a length of web located between said roller pairs to tear the web across one of the lines of perforation.

An apparatus and method of dispensing precise aliquots of cell culture media from a bulk, sterile, flexible container. The apparatus has load cell, a control valve, and a programmable controller. The container suspends from the load cell within the housing. The load cell continuously transmits to the controller an output signal, which represents the force, i.e., weight, of the bag on the load cell. The controller regulates the flow of media from the container by selectively activating the control valve. The controller precisely measures the volume of fluid media dispensed from the container by continuously calculating the change in weight of the container using the load cell output signal.

A glass safety tube with an encapsulating protective safety barrier that contains the glass tube and its contents if the glass tube is fractured. The glass tube has a length L, an elongate tubular central portion with a diameter D and a length L, which is less than L, an open end, and, a closed end portion integrally formed with the central portion and axially extending a distance Lfrom the central portion. A first safety barrier envelops the central portion of the glass tube. A second safety barrier envelops the closed end portion of the glass tube.

A method and apparatus for controlling bi-directional fluid flow. The apparatus has a pump that operates in a continuous pump cycle having a pressure phase and a vacuum phase. A conduit connects a common pump port to a utility port. An electrically-controlled valve regulates air flow through the conduit. The valve operates between a first position isolating the pump and the utility port, and a second position connecting the pump and the utility port in fluid communication. A detector continuously detects and communicates a signal identifying whether the pump is operating in the pressure or vacuum phase of the pump cycle. A controller uses the detector signal to synchronize actuation of the valve with the pump cycle to generate either continuous positive or continuous negative pressure at the utility port.

A valve for use in a pipette gun for selectively providing different ranges of flow rates through a pipette cooperating with the pipette gun. The valve has a predetermined number of discrete settings, each of which provides a range of fluid flow rates between zero and a different maximum flow rate. The operator controls the flow rate by depressing the gun trigger a selected distance. To change the flow rate setting, the operator simply rotates the gun trigger to a desired setting. The present valve also eliminates the "piston effect" of prior art valve elements by isolating the pipette chamber while the valve element operably slides in and out of engagement with a port thereby connecting the pipette with a fluid source either under pressure or at a vacuum.
