Abstract: A light-weight bottle stabilized against knockdown or tipping over comprising in combination, the bottle and a lead weight which weight is wrapped around the base of the bottle and wherein at least the surface contacting the bottle is covered with a cushioning material.

Abstract: A weight for stabilizing laboratory ware and the like comprising a lead disc having a plurality of pliable extensions which are essentially symmetrically spaced, said weight being coated with a flexible cushioning material such as polyvinylchloride.

Abstract: A supporting device for laboratory containers, bottles, and the like which comprises a helical spring joined at its ends to form a torus-shaped body with several turns of said spring being loosely affixed to a base, thereby permitting expansion of said torus-shaped body when an object having a dimension greater than the central opening of the torus is inserted therein. Preferably said helical spring is wound to have substantially no compression and tension between turns, a natural frequency between 10 and 100 cycles per minute, and the spring wire is of a thin, rectangular cross-section with the long side directed radially.

Abstract: Containers such as laboratory glassware are stabilized in their upright resting position by means of a split torus; e.g., a high density rod, preferably of essentially circular cross-section, bent into a substantially, but incompletely closed loop.
