A cell culture bioreactor has one or more cartridges. Each cartridge has layers of hollow fiber membranes potted in potting cavities of a two-part mold. Portions of the mold remain with the cartridge and define upper and lower surfaces and sidewalls of the potting cavities. A corresponding process for making the bioreactor is also described.

The single-hand-operable micro water purifier of the present application relates to a micro water filter, especially a micro water purifier which can filter water by pressurization. It includes a micro filter device and a raw water pressurizing device. The micro filter device includes a filter cylinder body, a filter water inlet, and a filter water outlet and a filter material assembly located in the filter cylinder body. The raw water pressurizing device includes a pressurizing device water inlet, a pressurizing device main body, and a pressurizing device water outlet. The present application can promote the raw water to enter the filter device for performing the filtration to obtain the clean water, by using a single hand to operate, which not only brings convenience to the user, but also saves labor and improves the use efficiency.

There is provided a chemical analyzer equipped with a hollow fiber degassing module that can maintain the original excellent degassing performance even after long periods of continuous use. More specifically, a hollow fiber degassing module 20A includes a housing 210 and a hollow fiber membrane 220 disposed in an internal space S1 of the housing. The housing 210 includes a liquid supply unit 216A for connecting an outside of the housing 210 and an internal space S2 of the hollow fiber membrane 220 to each other, and for supplying constant temperature water W1 from an outside of the housing 210 to an internal space S2 of the hollow fiber membrane 220, a liquid discharge unit 217A for connecting the internal space S2 of the hollow fiber membrane 220 and the outside of the housing 210 to each other, and for discharging constant temperature water W2 degassed from the internal space S2 of the hollow fiber membrane 220 to the outside of the housing 210, a gas discharge unit 218A for connecting an internal space S1 of the housing 210 and the outside of the housing 210 to each other, and for depressurizing the internal space S1 of the housing 210, and a liquid discharge unit 219A that is provided at a vertically lower end portion of the housing 210 for discharging a liquid generated in the housing 210.
