Abstract: The present invention provides a sample container holder for securely holding sample containers of various shapes and sizes. The holder comprises a base having at least one slot extending from an upper portion of the base to a lower portion of the base. The holder further comprises at least one retainer inserted into the slot creating at least a partial enclosed area on the base to accommodate the sample container.

Abstract: A laboratory rack assembly for supporting columns and receptacle tubes and other paraphernalia during laboratory procedures such as such as filtration, chromatography, plasma preparation, affinity purification, and so on, includes upper and lower support portions that are connected together for relative sliding movement. An upper rack module is connected to the upper support portion and is configured to receive at least one column. A lower rack module is connected to the lower support portion and is configured to receive at least one receptacle tube. At least one of the rack modules is removably connected to at least one of the support portions. An adjustment mechanism is operably associated with the upper and lower support portions for adjusting a position of one support portion with respect to the other support portion to thereby vary the distance between the upper and lower rack modules.

Abstract: A utensil for a manually impaired user includes a utensil insert, such as a fork, spoon, knife, tool or other object, and a handle for receiving the utensil insert so that a portion of the utensil insert extends outwardly from the handle. The handle has first and second handle sections that are removably connected together. The first handle section includes a first receptacle and a first projection spaced from the first receptacle while the second handle section includes a second receptacle and a second projection spaced from the second receptacle. The first receptacle is adapted to receive the second projection and the second receptacle is adapted to receive the first projection when the first and second handle sections are connected together.

Abstract: A toilet seat elevator assembly includes a mounting bracket for connection to a toilet bowl and a seat elevator removably connected to the mounting bracket. The seat elevator has a generally ring-shaped portion for resting on the toilet bowl and a mounting portion with opposing mounting projections. The mounting bracket has a pair of opposing side panels and an elongate slot formed in each side panel. Each elongate slot is adapted for slidably and rotatably receiving the mounting projections of the mounting portion, so that the seat elevator may be slidably and rotatably mounted to the bracket to facilitate installation, adjustment and removal of the seat elevator with respect to the toilet bowl.

Abstract: An enclosed magnetic stirring bar arrangement includes a housing formed by front and rear walls interconnected by a peripheral wall, so as to define a substantially hollow interior chamber within said housing. An operational opening is formed within the front wall and at least one discharging aperture is provided in the peripheral wall. A magnetic stirring member is movably positioned within the substantially hollow interior chamber, whereby rotational motion of the magnetic stirring member facilitates entering a liquid into the substantially hollow interior chamber and discharging the liquid from the interior chamber through the at least one discharging aperture.

Abstract: A spherical vacuum desiccator consists of two substantially identical shells which are connected together at an engagement region. A receiving segment and connecting segment are positioned in a spaced-apart relationship within the engaging region of each hemispherical shell. In the assembled condition of the invention, each hemispherical shell is disposed in an inverted position with respect to the other shell and the connecting segment of the two hemispherical shells engage at the receiving segment.

Abstract: A non-metallic adapter provided to facilitate the rotation of a doorknob is formed with a cap adapted to receive a doorknob. A lever extends outwardly from the cap. The lever is formed with an internal cavity provided with a plurality of reinforcing members separating the cavity into a plurality of substantially isolated reinforced regions.

Abstract: A device for producing a solidified block of carbon dioxide includes first and second housing portions removably connectable together. The first and second housing portions form an interior molding chamber that is adapted to receive liquid carbon dioxide at a pressure where expansion of the liquid carbon dioxide occurs, resulting in a mixture of solidified and gaseous carbon dioxide. A pressure relief device includes a biasing member for biasing the first and second housing portions together. The biasing member permits relative movement between the first and second housing portions when internal pressure from the gaseous carbon dioxide exceeds a predetermined amount. With this arrangement, relative movement between first and second housing portions causes gaseous carbon dioxide to be released from the interior molding chamber to thereby reduce the internal pressure.

Abstract: A modular laboratory cabinet assembly consists of a pair of identical housing end units arranged in an inverted spaced apart relations to each other, and at least a pair of identical base housing modules arranged in an inverted side by side relations to each other and interposed between the housing end units.

Abstract: A hosiery donning aid apparatus comprises a body formed as a channel having interior and exterior surfaces and two outer edges extending along a longitudinal axis of the body. A frictional arrangement is provided consisting of a multiplicity of spaced from each other frictional ribs extending outwardly from the exterior surface in such a manner that a substantial gap separates each end of each frictional rib from the respective outer edges.

Abstract: A housing assembly includes first and second sides and first and second panels spaced apart from each other by an interior of the housing and traversing the first and second sides. A first porous desiccant retention plate and a second porous desiccant retention plate are spaced from each other are secured within the housing so as to define a desiccant chamber therebetween for maintaining the desiccant medium. An opening is formed within one of said panels in a location corresponding to the location of the desiccant chamber, facilitating replacement of the desiccant medium within the desiccant chamber.

Abstract: A non-metallic laboratory jack comprises two oppositely disposed reinforcing elements having I-beam cross-sectional configuration disposed in the central elevational region of the jack; a base position below the reinforcing elements and a load-bearing platform positioned above the reinforcing elements and a plurality of pairs of cross links. A rotatable threaded shaft associated with the reinforcing elements.

Abstract: A pipette control arrangement consists of a housing assembly adapted for operatively housing a pump assembly and for operatively connecting a pipette to the pump assembly via a flexible air tube. The pump assembly is adapted to independently accommodate a plurality of volume specific removable cylinder-plunger systems. The pipette control arrangement may further include a quick release trigger operated mechanism for rapidly and or in large volumes dispensing liquid from an attached pipette.

Abstract: A hosiery donning aid consists of a base, at least one hosiery support and at least one handle support. The hosiery support has a support element carried by the base. The handle support has a handle outwardly extending from the base in adjacent relationship to the hosiery support.
