A heat sealing product suitable for seating one or more individual containers, said heat sealing product comprising: (i) a plurality of individual heat seals set out in a configuration substantially corresponding to the shape and configuration of the container(s) to be sealed, the size and shape of the individual heat seals corresponding substantially to the size and shape of the tops of the individual container(s) to be sealed; (ii) a peelable support film layer coated on one side with a low tack adhesive, the low tack adhesive serving to hold the individual heat seals in place on the support film layer in the desired configuration prior to the sealing process; (iii) alignment points in the sealing product adapted to enable the heat sealing product and therefore the individual heat seals of the heat sealing product to be aligned substantially exactly with respect to the individual containers to be sealed.

The present disclosure relates to a laboratory sample container carrier handling apparatus comprising a revolving device, being adapted to move a sample container carrier supplied to the revolving device along a circular path P, and wherein the circular path P has at least one ascending ramp. The present disclosure relates further to a laboratory sample distribution system comprising such a laboratory sample container carrier handling apparatus.

Provided is a cryopreservation jig fixture including: a base having an upper surface, side surfaces, and a bottom surface; and either a slit on the upper surface of the base or an insertion portion for inserting a cryopreservation jig on the upper surface of the base and a slit having one end opened at a lateral portion of the insertion portion. Also provided is a method of freezing and thawing a cell or tissue, which uses the fixture.

Multivolume liquid pipettes with nested plunger and vacuum chamber configurations and methods of using such pipettes are disclosed herein. These pipettes typically include a body and a fluid displacement assembly with a small plunger element slideably received within a larger plunger element, each movable within a vacuum chamber for the precise and accurate control of the displacement of fluid, such as air. In turn, this allows for a single device to aspirate and dispense a broad range of liquids in a dynamic, accurate, and precise manner. In addition, the devices disclosed herein may also include a multi-tiered spring-loaded ejection mechanism to allow the user to use and eject pipette tips of different sizes.

A heat sealing product suitable for sealing one or more individual containers, said heat sealing product comprising: (i) a plurality of individual heat seals set out in a configuration substantially corresponding to the shape and configuration of the container(s) to be sealed, the size and shape of the individual heat seals corresponding substantially to the size and shape of the tops of the individual container(s) to be sealed; (ii) a peelable support film layer coated on one side with a low tack adhesive, the low tack adhesive serving to hold the individual heat seals in place on the support film layer in the desired configuration prior to the sealing process; (iii) alignment points in the sealing product adapted to enable the heat sealing product and therefore the individual heat seals of the heat sealing product to be aligned substantially exactly with respect to the individual containers to be sealed.

A system comprising a calorimeter for measuring a heat flux of a sample comprising a recipient space for a sample container containing a sample, a heat sink, a first heat transducer whereby the first heat transducer comprises a heat receiving surface in contact with the sample container when the sample container is positioned in the recipient space and a heat absorbing surface in contact with the heat sink. A second heat sink is provided, whereby the second heat sink has a second heat receiving surface in contact with the heat sink and a second heat absorbing surface in contact with the sample container, when the sample container is positioned in the recipient space.

A test tube rack having at least one perforated surface for the insertion of tubes that are held in a vertical position is disclosed. The rack being formed by at least one first pre-cut cardboard sheet is provided with fold lines that, prior to use, defines a laminar body having a minimal thickness, and, at the time of use, it may be assembled to form a volumetric body having at least one upper platform including perforations and maintaining the vertical position of the tubes inserted into the perforations, in turn, can be adjusted to the diameter of the tube as to receive tubes of different diameters. The test tube rack may have a second lower platform with perforations positioned in vertical alignment with the perforations in the upper platform that the tubes inserted therein are gripped at two heights.

A receptacle holder having a base body, a first perimeter wall which at least partially protrudes from the base body, and a plurality of resilient elements, which are distributed about a first axis of the receptacle holder and are detachably connected with the first perimeter wall, and wherein each resilient element comprises a first end portion and a second end portion, and wherein each second end portion rests hooked over an edge of a portion of the first perimeter wall, and wherein the receptacle holder is configured to allow sliding of each second end portion in a direction perpendicular to the first axis.

A combination includes: a holding structure including receptacles which are arranged in a regular arrangement and are formed by peripherally formed side walls; containers received in the receptacles, the containers having a basic body which, at an upper end, merges into a shoulder portion which is adjoined by a narrowed neck portion with a widened upper edge with an opening; holding projections provided at lower ends of the receptacles and configured to hold the containers in the receptacles, the holding projections at the lower ends protruding radially inwards into the receptacles, the containers being supported directly on the holding projections; and centering elements provided above the holding projections and configured to center the containers in the receptacles. The centering elements have a beveled configuration and protruding into the receptacles in order to reduce a width of the receptacles at the lower ends thereof in a funnel shape.

Systems and methods for handling a variety of sample and preparatory fluids in a rack specifically configured for compatibility with predetermined liquid handlers such as automated pipettors or multi-channel manual pipettors and set up for magnetic based sample preparation. The rack can hold all of the necessary sample and reagent vials, and present them to the pipettor in some embodiments in a way that allows for parallel operation. The rack includes slidable magnets that in some embodiments are actuatable directly by the pipettor, eliminating a layer of complexity. Combined with a suitable pipettor the magnet enabled rack supports a multistep magnetic based sample preparation capability in a high throughput manner at one station that enhances sample purity throughout magnetic separation processes.
