Abstract: Disclosed herein are flask clamps that capture and firmly hold flasks or vessels of various shapes, enclosing the sidewall of the flask or vessel in a trap or loops. The trap relatively conforms to the profile of the perimeter of the vessel and are spring loaded in the upward direction in order to rise upward along the sides of the vessel. The loops pivot relative to the bottom of the flask creating an arc motion that tightens against the sidewall as it rises. The loaded loops are in tension against the flask, and the multiplicity of loops hold vessels in tension with opposing forces.

Abstract: Disclosed herein are devices for the purification of water that use a heat pump. The purification system comprises a heat pump and the heat pump comprises a refrigerant condenser, a refrigerant evaporator, a compressor, and a throttle valve that are fluidly connected with a circulating refrigerant along a refrigerant line. The circulating refrigerant transfers heat to a contaminated feedstock at the refrigerant condenser to vaporize at least a portion of the contaminated feedstock. Also disclosed are methods of purifying water, washing systems comprising a washer and a water purification system, washing and drying systems comprising a washer, a dryer, and a water purification system, and methods for cleaning and/or drying of clothes.

Abstract: A clamp for an Erlenmeyer flask or other laboratory containers or racks uses nickel-coated, rare earth magnets to secure the clamp to a platform for a laboratory shaker. The base of the clamp has downwardly extending positioning bosses that seat in holes or indentations on the shaker platform to prevent horizontal sliding of the clamp when the shaker is in use. A removable and replaceable, elastomeric cover for the base of the flask clamp provides cushioning and prevents spinning of the flask when the shaker is in use.
