A liquid pumping device includes a liquid pumping tube module, an axial movement module, a rotation module and a translation module. The liquid pumping tube module includes a tube and an adapter. The tube has a first end and a second end in an axial direction. The adapter is disposed at the second end. The axial movement module is connected to the tube, and drives the liquid pumping tube module to move in the axial direction. The rotation module is connected to the liquid pumping tube module, and drives the liquid pumping tube module to rotate relative to a rotation axis of the rotation module. The translation module is connected to the liquid pumping tube module, and drives the liquid pumping tube module to move on a plane perpendicular to a plane of rotation of the rotation module.

In one embodiment, a method for dispensing a filled container comprises removing a single container from a stack of containers within a chassis, filling the single container with filtered water within the chassis, sealing the single container within the chassis, and dispensing the single container from the chassis. In another embodiment, a system for dispensing a filled container comprises a chassis, a stack of containers within the chassis, and an automated mechanism within the chassis to remove a single container from the stack of containers, fill the single container with filtered water, seal the single container, and dispense the single container from the chassis.

A capping and de-capping apparatus for capping and de-capping tubes disposed in a tube holding rack having a two-dimensional array of apertures for holding the tubes. The apparatus comprises a rack support for supporting the tube holding rack, a head unit adapted for carrying a cartridge comprising at least one capping and de-capping gripper, a drive system for moving the rack support and the head unit relatively towards and away from one another, in order to cause engagement or disengagement of the capping and de-capping gripper with or from a cap of at least one tube, and a drive system for rotating the capping and de-capping gripper, wherein rotation in one direction causes attachment of the cap to the tube and rotation in the opposite direction causes detachment of the cap from said tube.

A cap gripper cartridge for releasably connecting to a head unit of a test tube capper-decapper device is herein disclosed, the cap gripper cartridge comprising a cap gripper holder rotatably bearing a plurality of cap grippers arranged in a 2-dimensional array; and a cap ejector plate comprising a plurality of throughbores respectively arranged around a respective cap gripper of the plurality of cap grippers between the cap gripper holder and a respective cap socket comprised in a respective cap gripper; the cap ejector plate arranged for being displaced relative away from the cap gripper holder for engaging at least one test tube cap retained by the respective cap socket, and effecting a release of the at least one test tube cap by the displacement.

A handheld, battery operated device that, when activated, will grip a screw-cap on the top of a cryogenic vial, microtube, test tube or other pharmaceutical product container, and automatically rotate the cap in a counterclockwise direction to remove the cap, and automatically rotate the cap in a clockwise direction to fasten the cap back on the cryogenic vial, microtube, test tube or other pharmaceutical product container.

In a hand-held capper/decapper device, cap drivers in an array are driven by an array of rotary motors that drive the cap drivers in forward and reverse rotary directions to cap and decap caps from threaded receptacles. A common linear drive drives ejector pins through the centers of cap drivers to eject caps from the cap drivers. Single button operation is enabled by a controller that responds to press and release of a control button to alternate between decap and cap functions. The cap function finishes with ejection by extension of an ejector pin. An ejector button may also be provided for ejection without rotation of cap drivers. The cap drivers float against compression springs that apply axial force to the cap drivers. Ejection of the caps is staggered to reduce force required. Replaceable cap drivers designed to corresponded to cap designs are supported in a removable cartridge that is retained on a hand-held housing by magnets.

A capping and de-capping apparatus for capping and de-capping tubes disposed in a tube holding rack having a two-dimensional array of apertures for holding the tubes. The apparatus comprises a rack support for supporting the tube holding rack, a head unit adapted for carrying a cartridge comprising at least one capping and de-capping gripper, a drive system for moving the rack support and the head unit relatively towards and away from one another, in order to cause engagement or disengagement of the capping and de-capping gripper with or from a cap of at least one tube, and a drive system for rotating the capping and de-capping gripper, wherein rotation in one direction causes attachment of the cap to the tube and rotation in the opposite direction causes detachment of the cap from said tube.
