There is provided an apparatus and a method for producing a play compound and the play compound itself which, in one embodiment is a compound which sufficiently fluid to be pliable and is typically cold and slimy to the touch. The apparatus and a method provide a powder and liquid to a user, which can be a non-skilled person and thereby allow the mixing of the powder and liquid together by that person to form the play compound outside of a factory environment whilst ensuring that the play compound which is formed has the desired characteristics. Most typically the user which performs the mixing can be the end user, such as a child, who will play with the compound and so the formation of the play compound forms a new part of the play experience.

Methods and systems for purifying a caustic fluid including sulfur are provided.

An example microfluidic mixer can include an inlet microfluidic channel portion and a fluid splitting channel portion including an overpass microfluidic channel to receive fluid from a first side of the inlet microfluidic channel portion and an underpass microfluidic channel to receive fluid from a second side of the inlet microfluidic channel portion, where the underpass microfluidic channel extends under the overpass microfluidic channel such that the channels overlap at their respective downstream ends. A fluid recombining channel portion is downstream of the fluid splitting portion and includes an angled recombining surface having an acute angle with respect to a direction of fluid flow, where the angled recombining surface is between the downstream ends of the overpass and underpass microfluidic channels. An outlet microfluidic channel portion is fluidly connected downstream from the fluid recombining channel portion.

An exemplary compounding system and method can include a transfer set that includes a manifold for assisting in transferring a plurality of ingredients from supply container(s) to a final container. The manifold can include a first channel in fluid communication with at least one primary ingredient, and a second channel in fluid communication with a plurality of secondary ingredients. The first channel and second channel can be in fluid isolation from each other such that the at least one primary ingredient does not mix with the plurality of secondary ingredients within the manifold. The transfer set can include a plurality of inlet lines in fluid communication with the manifold and two outlet lines configured for connection to two separate pumps and eventually being in fluid communication with the final container.

An exemplary compounding system and method can include two pump heads for simultaneously drawing two different fluids from at least two separate input containers such that the at least two different fluids are mixed and distributed to an output container. The system can include a manifold that maintains separation of certain of the different fluids until after passing by a first pump and a second pump and/or additional pumps. A junction can be placed in the fluid line downstream of the first and second pumps and/or additional pumps such that all or some of the fluids are mixed prior to output to the output container. The method of using the system can include incorporating software that selects various fluids at certain times and sequences to ensure optimum efficiency and safety for the system, and can continue compounding actions even when an input supply container runs out or otherwise fails to supply a particular fluid/material. The method of use also includes connection of a transfer set to a housing in a manner that further ensures optimum efficiency and safety.

Examples include microfluidic devices. Example microfluidic devices include a first microfluidic channel, a second microfluidic channel, and a third microfluidic channel fluidly coupled to the first microfluidic channel and the second microfluidic channel via a fluid junction. A fluid actuator is disposed in the third microfluidic channel to actuate to thereby pump a first fluid and a second fluid into the third microfluidic channel.

The present invention relates to multi-bed catalytic reactor with a cylindrical shape comprising a mixing device mounted between two catalyst beds in the reactor, said mixing device comprises connected pipe segments forming mixing section and discharging section.
