A holding structure for holding a plurality of containers for pharmaceutical, medical or cosmetic purposes includes a carrier having openings or receptacles for accommodating the containers. Holding devices for holding the containers are provided at the openings or receptacles. The holding devices can selectively assume two different stable positions, namely a first stable position in which the containers can be inserted without friction into the openings or receptacles and a second stable position in which the containers are held in the respective opening or receptacle by frictional engagement or by positive locking. The containers can be reliably inserted into the openings or receptacles without material abrasion. In the open insertion position of the holding devices, a large number of containers can be inserted concurrently into the openings or receptacles without high forces acting on the holding structure.

METHODS AND DEVICES FOR BIOCOMPATIBLE GLASS-BOTTOM MICROSCOPY CHAMBERS

A device for imaging sensitive biological samples is provided. The device can include a plastic frame and a glass coverslip, each can be comprised of a biologically compatible material. The device can then be configured such that a biological sample placed therein can only be in contact with biologically compatible materials and, when imaged, provide optimal imaging characteristics by allowing imaging through the glass coverslip.

Sample staining device

A sample staining device, comprising a staining platform provided with a staining solution and cleaning solution supply part; glass slide support structures located on either side of the staining platform and forming a certain clearance between a glass slide and the staining platform; and a glass slide driving mechanism that enables the glass slide to move while maintaining a certain clearance from the staining platform. When said device works, a staining solution is supplied to the staining platform, and a convex liquid surface is formed due to surface tension; when the glass slide moves to the convex liquid surface of the staining solution, the staining solution infiltrates and diffuses in the clearance formed between the staining platform and the glass slide to cover the glass slide so as to stain a sample; and after the glass slide is stained, a cleaning solution is supplied to clean the residual staining solution.

Solid reagent containment unit, in particular for a portable microfluidic device for sample preparation and molecule analysis

A solid reagent containment unit is formed by a support; a frame body fixed to the support and delimiting internally, together with the support, an analysis volume; a reagent-adhesion structure within the analysis volume; and at least one reagent cavity, which extends within the reagent-adhesion structure. The reagent-adhesion structure is of an adhesion material embossable at temperatures lower by 6-8° C. than its own melting point and has a melting point such as not to interfere with the analysis. The reagent cavity forms a retention wall, laterally surrounding the reagent cavity, and houses dried reagents. The adhesion material is chosen among wax, such as paraffin, a polymer, such as polycaprolactone, a solid fat, such as cocoa butter, and a gel, such as hydrogel or organogel.
