Abstract: A holder for a micro-sized medical device, such as a pipette, includes a main body portion having an interior space sized for housing at least one pipette. A reducing insert comprising a sleeve has an open end and a substantially closed end. The sleeve is sized such that the open end is receivable in the main body portion through an open axial end of the main body, and the substantially closed end has an aperture extending therethrough having a diameter sufficient for passage of a pipette therethrough. An end cap is engageable with the open axial end of the main body portion, and is selectively movable between an open position wherein the interior space of the main body communicates via the aperture with an environment exterior of the holder, and a closed position wherein the seal covers the aperture. The components of the holder may be formed integrally or separately.

Abstract: A device for support and protection of a tubular element having a single-piece construction, an open configuration and a closed configuration, comprising: a base portion, a side-portion and at least one living hinge interconnecting the side-portion to the base portion. The base portion comprises a plurality of recesses on a surface, each recess being delimited by a plurality of pins, each pin having an indentation. The plurality of indentations form a pocket by which the tubular element is held. The at least one living hinge opens such that the side-portion is substantially parallel to the base portion in the open configuration and the at least one living hinge closes such that the side-portion forms a protective shell about the base portion in the closed configuration.
