A nail polish removing apparatus includes a container including an outer wall and an open top edge portion having a threaded outer surface. A first lid includes a centrally disposed threaded lip portion and a recessed portion aligned with the lip portion. The apparatus further includes a second lid, attachable to the lip portion, and provided with an annular opening. An elongated wand having opposed end portions and a cleansing head is also included. The slot and the opening are such that the cleansing head can be positioned through the slot but not the opening. The wand has a lower portion smaller than the opening so that the second lid can be detached from the first lid without causing the wand to rotate. The cavity is larger than the cleansing head such that an entire length of the cleansing head can be maintained within the cavity.

A protein crystal growth tray assembly includes a tray that has a plurality of individual crystal growth chambers. Each chamber has a movable pedestal which carries a protein crystal growth compartment at an upper end. The several pedestals for each tray assembly are ganged together for concurrent movement so that the solutions in the various pedestal growth compartments can be separated from the solutions in the tray's growth chambers until the experiment is to be activated.

A clinostat for simulating microgravity on cell systems carried in a fiber fixedly mounted in a rotatable culture vessel. The clinostat is rotated horizontally along its longitudinal axis to simulate microgravity or vertically as a control response. Cells are injected into the fiber and the ends of the fiber are sealed and secured to spaced end pieces of a fiber holder assembly which consists of the end pieces, a hollow fiber, a culture vessel and a tension spring with three alignment pins. The tension spring is positioned around the culture vessel with its ends abutting the end pieces and the alignment pins extend between the end pieces for alignment of the spring. After the fiber is secured, the spring is decompressed to maintain tension on the fiber while it is being rotated. This assures that the fiber remains aligned along the axis of rotation. The fiber assembly is placed in the culture vessel and culture medium is added. The culture vessel is then inserted into the rotatable portion of the clinostat and subjected to rotate at selected rpms. The internal diameter of the hollow fiber determines the distance the cells are from the axis of rotation.
