A laboratory device, in particular a rotary evaporator, serves for evaporating a substance, preferably under reduced pressure, and comprises an evaporation flask for receiving the substance to be evaporated, a condenser for condensing the evaporated substance and a vapor passage for passing through the evaporated substance, which vapor passage is arranged in a vapor path between the evaporation flask and the condenser. The laboratory device further comprises a detection unit for foam detection, which detection unit is provided outside of the vapor passage and/or the evaporation flask.

The present invention provides an industrial wastewater recovery apparatus (100) aiming at Zero Liquid Discharge (ZLD). The apparatus (100) provides two stages in pre-heating the spiral coil pipe (103) containing wastewater and also conserves the heat by using the two heat exchangers (104, 105). The apparatus (100) agitates the surface wastewater to increase the rate of evaporation for faster heating. The apparatus (100) provides two stages in condensation of distilled water and also provides real-time monitoring of the water quality. The apparatus (100) provides automatic cleaning in the various parts during the operations. Further, a plurality of IoT sensor (201) monitor the real time parameters of the industrial wastewater recovery apparatus (100) and data is available to the user on the electronic display device (204).

An example device includes a defrothing portion to separate froth into a coalesced fluid and air, an air vent to vent the air from the defrothing portion, and a membrane on an outer surface of the defrothing portion, the membrane sealing the air vent. The membrane is formed of a material to prevent fluid from passing therethrough.

The present invention relates to a process for preparation of a composition comprising gas microbubbles. More particularly the invention relates to a process for filling of such composition into a container. The composition prepared is preferably an ultrasound contrast media composition made available in a container wherein the headspace of the container comprises the same gas as the gas of the microbubbles.

Disclosed is a rake-free thickening device including driving area. The device includes a feed assembly, a diversion assembly and a clean coal collection assembly. The clean coal collection assembly includes a driving area. The diversion assembly includes a central tank. Slime water passes through the feed assembly and flows with a medicament from an upper part of the central tank to a middle of the central tank, and then diffuses around. Bubbles carry the fine slime up after reacting. The driving zone drives the dispersed bubbles to a defoaming zone located in the middle of the central tank. The slime water in the central tank flows through the central tank after defoaming. With the continuously filling of slime water, the slime water above the central tank overflows the central tank to the clean coal collection assembly within the diversion and settlement area.
