3. A portable workstation as claimed in claim 2 wherein said horizontal supports are hingedly connected to both of said two walls, with one or more said horizontal supports being connected to one of said two walls to support said first section and one or more of said horizontal supports being connected to the other of said two walls to support said second section.
4. A portable workstation as claimed in claim 1 wherein said horizontal supports are hingedly connected to both of said walls and are located to support each section of said work surface.
5. A portable workstation as claimed in claim 4 wherein said two sections of said work surface meet alone a common imaginary line.
6. A portable workstation as claimed in claim 5 wherein said common imaginary line is linear and extends at an angle between said two sections.
7. A portable workstation as claimed in claim 6 wherein said imaginary line is located at a forty-five degree angle to a longitudinal axis of each section.
8. A portable workstation as claimed in claim 1 wherein there is at least one foldable shelf with at least one support to hold said at least one foldable shelf in a horizontal position when said at least one shelf is in said operating position.
9. A portable workstation as claimed in claim 8 wherein said workstation has a latch and catch to hold said two walls together when said workstation is in a closed position.
10. A portable workstation as claimed in claim 8 wherein said workstation and said at least one shelf in a position substantially parallel to said two walls when said station is in a closed position or in an operating position.
11. A portable workstation as claimed in claim 1 wherein, in said closed position, said workstation having a footprint that is substantially long and narrow with said length being longer than said width by at least a factor of five.
12. A portable workstation as claimed in claim 11 wherein said factor is at least a factor of ten.
13. A portable workstation as claimed in claim 1 wherein there is a foldable peninsula one end of said work surface, said peninsula extending inward from the wall of said two walls to which it is hingedly connected, a free end of said peninsula being supported by a foldable leg.
14. A portable workstation as claimed in claim 13 wherein said peninsula meets said end of said work surface along a common line.
15. A portable workstation as claimed in claim 1 wherein the two walls have at least one of wheels or casters spaced along a bottom thereof.
16. A portable workstation as claimed in claim 15 wherein the walls have legs thereon and the wheels or casters are located at the base of each leg.
17. A portable workstation as claimed in claim 1 wherein there is a horizontal support mounted on said elongated member to support said work surface.
18. A portable workstation as claimed in claim 17 wherein there are at least two horizontal supports hingedly mounted on each wall to support said work surface.
19. A portable workstation as claimed in claim 18 wherein one of said horizontal supports is located at an end of each wall and has a wheel or caster at a base thereof.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A test tube carrier for transporting test tubes in a transport system, said carrier comprising
a base having a recess made thereto for accommodating the bottom of a test tubevial; and
support members adapted to the carrier base for clamping a test tube inserted in said test tube recess and supporting the same, said support members being permanently affixed to said carrier base and comprising elongated portions with their free ends bent toward the vertical center axis of the carrier base and said upper ends providing a support surface for making supportive contact to the test tube, characterized in that wherein the support surface of said support members is arranged to extend to at least two different heights from the top level of the carrier base and said carrier base being assembled from two concentrically insertable parts leaving therebetween recesses into which the lower ends of said support members are permanently affixed.
2. The test tube carrier of claim 1, the bottom of said test tube recess is flat.
3. The test tube carrier of any one of foregoing claims, wherein the upper end of said support members include a hooked finger portion directed toward the vertical center line of the carrier base and then toward the carrier base.
4. The test tube carrier of claim 3, wherein said support members are made from a flat band material.
5. The test tube carrier of claim 3, wherein said support surface forms a horizontally lineal contact surface aligned perpendicular to the center axis of the test tube.
6. The test tube carrier of claim 4, wherein said support surface forms a horizontally lineal contact surface aligned perpendicular to the center axis of the test tube.
