The concepts herein relate to a device for collecting, transferring and storing samples of biological and/or chemical material. The device includes a support body extending along a main longitudinal direction between a first and a second end opposite each other and a collecting portion engaged with one of said ends of the support body and suitable for collecting an amount of a sample of biological and/or chemical material. The support body is defined by at least a first sub-body and a second sub-body extending longitudinally and configured to be selectively engaged and separated with and from each other. The support body is configured to operate between an assembled condition, wherein the first and the second sub-body are engaged with each other, and a separated condition, wherein the first and the second sub-body are separated and bear, respectively, a first and a second sub-collecting portion of the collecting portion.

A container for accommodating pharmaceutical compositions, which is installable in a medical device, is provided. The container includes a hollow cylindrical body having an open end and a dead end opposite to the open end. The dead end is closed by a bottom portion. The hollow cylindrical body and the bottom portion are formed integrally and of the same material. The bottom portion transitions into the hollow cylindrical body via a curved heel that is defined by an outer radius r.sub.o, an inner radius r.sub.i and a thickness d.sub.h in a center portion of the curved heel, wherein the following condition is fulfilled: r.sub.i+d.sub.hr.sub.o>0 mm.

A separation container for extracting a portion of a sample for use or testing and method for preparing samples for downstream use or testing are provided. The separation container may include a body defining an internal chamber. The body may define an opening, and the body may be configured to receive the sample within the internal chamber. The separation container may further include a seal disposed across the opening, such that the seal may be configured to seal the opening of the body, and a plunger movably disposed at least partially inside the internal chamber. The plunger may be configured to be actuated to open the seal and express the portion of the sample.

A pipette tip for use with a pipettor including a pipettor shaft having a terminal end has opposed proximal and distal ends and includes a tubular body and a coupling portion. The tubular body extends between the proximal and distal ends. The tubular body define a fluid passage terminating at a proximal opening adjacent the proximal end and a distal opening adjacent the distal end. The coupling portion is located on the proximal end. The coupling portion includes an interlock feature configured to mechanically interlock with the pipettor shaft proximate the terminal end to selectively and releasably secure the pipette tip to the pipettor shaft.

Pipette tip coupler and a disposable pipette tip for a pipette device comprises a stepped coupler shoulder complementary to an axially stepped pipette tip shoulder; a plurality of circumferentially disposed elements or segments carried by the coupler at a location superior to the coupler shoulder; and a distal elastomeric element carried by the coupler at a location distal to the coupler shoulder wherein the plurality of elements or segments have a circumferential, radially translated state that provides an abutment with a first working surface formed in the interior surface of the tip while compressing the distal elastomeric element into sealing abutment with a second working surface formed in the interior surface of the tip and while abutting the proximally facing axial stop surface of the tip with the distally facing axial stop surface of the coupler to define an axial coupling position of the pipette tip on the pipette device.

Pipette assembly that includes a pipette device, a pipette tip, and a leaf spring coupling device coupling the tip to the pipette device, the coupling device comprising a plurality of circumferentially disposed elements or segments in the form of flexible leaf springs with stabilizer plateaus used to retain a pipette tip to the coupler and prevent the pipette tip from rocking on the coupler and a distal elastomeric element, such as an O-ring, and the pipette tip comprising dual complemental working surfaces in the pipette tip to provide precise control of an axial coupled position defined as an axial distance from a distally facing axial stop surface of the pipette tip coupler to the end of the pipette tip that contacts liquid when the pipette tip coupler and disposable pipette tip are in a coupled configuration.
