Modular test tube rack
First Claim
1. A modular test tube rack for stacking assembly with similarly constructed racks comprising:
- a flat rectangular body having a top wall, a bottom wall, opposite side walls and opposite end walls;
said body displaying, in a first position, a first series of wells extending from said top wall in a direction towards said bottom wall and adapted to receive tubes therein;
each said end wall displaying a handle engaging extension;
a pair of handles respectively mounted at said opposite end walls;
each said handle having a lower portion engaging with said extension of said end wall and a hand gripping upper portion displaying a top edge extending above said top wall of said body;
said lower portion of said handles having a bottom edge so shaped as to anchor with the top edge of an underposed similarly constructed rack thereby enabling a vertically spaced stacking of two or more of said racks.

Abstract
A modular test tube rack for assembly with similarly constructed racks comprise a flat rectangular body displaying, in a first position, a series of wells extending from its top wall to its bottom wall and adapt to receive tubes therein. A pair of handles vertically extend at opposite end walls of the body, each handle having a lower portion adapted to tightly engage an extension on each end wall and a hand gripping upper portion. The lower portion has a bottom edge configured to anchor with the top edge of the handle of an underposed similarly constructed rack to thereby enable a stacking of two more of these racks. In one embodiment, the body displays a second series of wells extending from the bottom wall to the top wall whereby the body, when in a second position reversed relative to the first position, may also receive test tubes, the handles being reversably mountable to the end wall extension to still enable a stacking of racks in the second position.

13. A modular test tube rack for stacking assembly with similarly constructed racks comprising:
-
a flat rectangular body having a top wall, a bottom wall, opposite side walls and opposite end walls;
said body displaying, in a first position, a series of wells extending from said top wall in a direction towards said bottom wall and adapted to receive tubes therein;
each said end wall displaying a handle engaging extension;
a pair of handles respectively mounted at said opposite end walls;
each said handle having a lower portion engaging with said extension of said end wall and a hand gripping upper portion displaying a top edge extending above said top wall of said body;
said lower portion of said handles having a bottom edge so shaped as to anchor with the top edge of an underposed similarly constructed rack thereby enabling a vertically spaced stacking of two or more of said racks;
a cover having a top wall, opposite side walls and opposite end walls;
said side walls and end walls of said cover having lower edges adapted to rest on corresponding edges of said side walls and end walls of said body in said first position and on corresponding edges of said side walls and end walls of said body in said second position;
wherein said body displays, a second series of wells extending from said bottom wall to said top wall whereby, when said body is inverted to a second position inversed relative to said first position, it may receive other test tubes therein;
said handles being reversibly mountable to said extensions so as to enable a stacking of racks when said body is in said second position, said top wall of said cover displays at least one protuberance having a shape adapted to be received in a correspondingly located well entrance in said bottom wall of said body so as to allow a stack formation of covered racks; and
said cover comprises a pair of said protuberances at diagonally opposite corners of said top wall of said cover. - View Dependent Claims (14, 15, 16, 17)

18. A modular test tube rack for stacking assembly with similarly constructed racks comprising:
-
a flat rectangular body having a top wall, a bottom wall, opposite side walls and opposite end walls;
said body displaying, in a first position, a series of wells extending from said top wall in a direction towards said bottom wall and adapted to receive tubes therein;
each said end wall displaying a handle engaging extension;
a pair of handles respectively mounted at said opposite end walls;
each said handle having a lower portion engaging with said extension of said end wall and a hand gripping upper portion displaying a top edge extending above said top wall of said body;
said lower portion of said handles having a bottom edge so shaped as to anchor with the top edge of an underposed similarly constructed rack thereby enabling a vertically spaced stacking of two or more of said racks, wherein said extension of said end wall has a rectangular shape and wherein said lower portion of said handles displays a rectangular shaped opening to receive said rectangular extension of said end wall of said rack.
