Device for storage and transport of biological samples
View Patent ↗A device for storage and transport of biological samples. Multiple trays are assembled into a stack with sample tubes constrained between adjacent trays. The surface of each tray has radial grooves sized to hold the sample tubes. Each tray is secured to an adjacent tray with a bolt or snap-fit connector.
1. A device for storage and transport of biological samples, the device comprising:
a stack comprising at least a first tray and a second tray, each having a first surface with a first plurality of radial grooves and a second surface, opposite the first surface, with a second plurality of radial grooves, each radial groove terminating in a perpendicular groove that is perpendicular to a longitudinal axis of a corresponding radial groove in the plurality of radial grooves.
2. The device as recited in claim 1 , wherein each perpendicular groove is deeper than a corresponding radial groove in the plurality of radial grooves.
3. The device as recited in claim 1 , further comprising at least one Eppendorf tube disposed between, and contiguous with, the first tray and the second tray such that the at least one Eppendorf tube is retained within a radial groove within the plurality of radial grooves.
4. The device as recited in claim 1 , further comprising an indexed fastener with at least one flat edge, the indexed faster selected from a group consisting of an indexed hole and an indexed recess and an indexed protrusion.
5. The device as recited in claim 4 , wherein the first plurality of radial grooves is vertically offset from the second plurality of radial grooves such that the first plurality of radial grooves and the second plurality of radial grooves do not vertically align.
6. The device as recited in claim 1 , wherein the first tray and the second tray are circular discs.
7. The device as recited in claim 1 , wherein the first tray and the second tray each have a diameter that is less than 80 mm.
8. The device as recited in claim 1 , wherein the first tray and the second tray each further comprise a respective indexed hole with at least one flat edge, each indexed hole being disposed at a center of the respective tray, wherein the plurality of radially grooves extend radially from the respective center of the respective tray.
9. The device as recited in claim 8 , further comprising a bolt extending through the respective indexed hole of the first tray and the second tray.
10. The device as recited in claim 9 , wherein the bolt comprises an indexed shank with at least one flat edge.
11. The device as recited in claim 10 , further comprising a nut that is mated with the bolt.
12. The device as recited in claim 11 , further comprising a washer that is contiguous with the nut and the bolt.
13. A tray for storage and transport of biological samples, the tray comprising a first surface with a first plurality of radial grooves and a second surface, opposite the first surface, with a second plurality of radial grooves, each radial groove terminating in a perpendicular groove that is perpendicular to a longitudinal axis of a corresponding radial groove in the plurality of radial grooves.
14. The tray as recited in claim 13 , wherein the tray is a circular disc.
15. The tray as recited in claim 13 , wherein the first plurality of radial grooves is vertically offset from the second plurality of radial grooves such that the first plurality of radial grooves and the second plurality of radial grooves do not vertically align.
16. The tray as recited in claim 15 , wherein the tray further comprises an indexed hole with at least one flat edge, the indexed hole being disposed at a center of the tray, wherein the plurality of radially grooves extend radially from the center of the tray.
