摘要： A viscometer includes a viscosity sensor with a liquid flow channel for measuring a viscosity of a liquid flowing through the liquid flow channel, a manifold with an inlet and an outlet for receiving a liquid sample through the inlet of the manifold and providing the received liquid sample through the outlet of the manifold to the viscosity sensor, and a pump coupled with the manifold for causing an in-flow of the liquid sample into the manifold through the inlet of the manifold and an out-flow of the received liquid sample from the manifold through the outlet of the manifold. Also disclosed is a viscosity sensor module with two or more viscosity sensors.

摘要： Rheological measurement systems for use with systems including pressurized polymer melts and/or other viscous materials are described. In one embodiment, a rheometer is connected to an associated system with a bent, curved, or bendable tube to permit the rheometer to measure rheological properties in locations where the rheometer could not otherwise be located due to the presence of obstructions. Embodiments including rigid straight tubes for connecting a rheometer to an associated system are also described. In another embodiment, a flow-through rheometer is connected to an industry standard ½-20 thermowell aperture that is typically used for attaching temperature and pressure probes to a vessel containing a viscous material such as an extruder or injection molding system.

摘要： A viscosity measuring system is equipped with a tank, a flow pathway, an external force applying unit, and a pump. The viscosity measuring system further comprises a first pressure detection unit which detects a pressure of the electrode ink, and a second pressure detection unit which detects the pressure of the electrode ink on a more downstream side than the first pressure detection unit. A detection processing unit calculates a viscosity of the electrode ink based on the pressure detected by the first pressure detection unit and the pressure detected by the second pressure detection unit.

摘要： This invention relates in general to the field of cell-therapy treatments and more particularly, but not by way of limitation, to systems and methods for validating personalized cell-therapy treatments. In various embodiments, the system may calculate an aspiration volume needed for centrifugation to achieve a concentrated target threshold dose for a particular cell therapy using various factors such as, for example, information about a patient and the efficiency of the concentration process. In various embodiments, the system may also provide an indication to a physician of relevant published cell therapies to assist the physician in administering a treatment protocol.

摘要： A system for testing a rheological behavior of a slurry comprises a first stirring reactor, a second stirring reactor, a material supply pipe, a driving device, and a pressure detection member. The driving device has a first state and a second state. In the first state, the driving device drives a slurry in the first stirring reactor to be outputted to the second stirring reactor. In the second state, the driving device drives the slurry in the second stirring reactor to be outputted to the first stirring reactor. The pressure detection member is used to measure a pressure level in the material supply pipe.

摘要： An improved version of the capillary bridge viscometer that compensates for the effect of solvent compressibility is disclosed. A novel, yet simple and inexpensive modification to a conventional capillary bridge viscometer design can improve its ability to reject pump pulses by more than order of magnitude. This improves the data quality and allows for the use of less expensive pumps. A pulse compensation volume is added such that it transmits pressure to the differential pressure transducer without sample flowing there through. The pressure compensation volume enables the cancellation of the confounding effects of pump pulses in a capillary bridge viscometer.

摘要： A high-temperature, high-pressure, and low-velocity gas microtube viscosity measuring apparatus that comprises a thermotank, a fluid filtering and measuring device, a micro-pressure difference metering device, and a data acquisition and processing system. The fluid filtering and measuring device includes a filter, a microtube connector, a flow rate measuring liquid storage tank, an automatic micro-flow rate metering device, and an intermediate container connected in series via pipelines. The micro-pressure difference metering device is connected at two ends to pipelines at the two ends of the microtube connector via detection pipelines. The data acquisition and processing system is electrically connected to the micro-pressure difference metering device and the automatic micro-flow rate metering device to receive pressure difference data and flow rate data.
