Sample tube tray

A lacrosse stick head comprising a frame and netting attached to the frame, the frame comprising a throat portion, a side wall extending from the throat portion, and a lip portion joined to an end of the side wall remote from the throat portion, the netting being configured to define a ball pocket, and a rib on interior wall portions of the side wall and extending inwardly to overlie marginal portions of the netting.

Lacrosse stick head with inwardly extending side rib means

In accordance with the invention there is provided a Petri dish comprising a container for the growth of microorganism cultures and a lid for the container. The construction of the lid and the container provides an improved stacking feature when a plurality of Petri dishes are stacked. The container has improved features which provide a uniform media bed with more uniform depth and improved retention of the media.

Petri dish

A petri dish includes a bottom container member having a circumferential groove located in the bottom corner thereof. The groove facilitates the distribution of liquid culture media during the filling operation, assists in retaining the periphery of the solidified media in place to increase shelf-life, and provides a pleasing visual perception as to the media thickness when the petri dish is viewed from the side. The cover member includes an upstanding rib located on a top surface thereof, such that upon stacking the petri dish with another of like construction, the exterior surface of the circumferential groove and the upstanding rib cooperate to facilitate stacking. Also, the respective top and bottom walls of the cover and bottom container being 30% thinner than their associated side wall portions to provide in a savings in fabrication material.
