    • A viscometer includes a viscosity sensor with a liquid flow channel and at least two pressure sensors positioned along the liquid flow channel and configured to measure a pressure drop of a liquid flowing through the liquid flow channel, and a dispensing mechanism configured to cause dispensing of a liquid from the syringe to the viscosity sensor at a known flow rate. The dispensing mechanism and the viscosity sensor are configured to couple with a syringe configured to contain a liquid. The viscometer further includes an electronic controller configured to control operations of the dispensing mechanism and receive and process data from the viscosity sensor. The viscometer includes a sample loading interface, included in the syringe, through which the viscometer is configured to receive the liquid. The sample loading interface includes a selection valve coupled with, and located between, the viscosity sensor and the syringe.

    • This disclosure relates to a system and method for generating a change in pressure proportional to fluid viscosity. In particular, the disclosure discusses a viscosity dependent pressure differential system. The system can comprise a first pilot stream (103a), a second pilot stream (103b), and a pressure sensing device (107) that reads a differential pressure across a first junction (106a) on the first pilot stream (103a) and a second junction (106b) on the second pilot stream (103b). The first junction (103a) is between a first section (104a) having a first predominant pressure loss characteristic, and a second section (105a)having a second predominant pressure loss characteristic. Similarly, the second junction (106b) can be between a third section (105b) having a third predominant pressure loss characteristic and a fourth section (104b) having a fourth pressure loss characteristic.

    • Disclosed is a two station system for a flow cytometer that includes a sample station and a wash station. During washing, the user has access to the sample station to insert a new sample. This increases the efficiency of the workflow process. Rotary clamps are used to automatically clamp the sample station and wash station to the system. A low volume pressurized cavity is used to bring the pressure of the sample to a desired pressure, which further increases productivity of the system. A transparent body is provided in the sample station so a user can view the sample during the sampling process. A backwash process is used to clean the sample injection tube and the sample uptake tube. In addition, the wash station is designed to rinse the outer surface of the sample uptake tube.
    • 公开了一种用于流式细胞仪的两站系统,其包括采样站和洗涤站。 在洗涤期间,用户可以访问样品台以插入新的样品。 这提高了工作流程的效率。 旋转夹具用于自动将样品站和洗涤台夹在系统中。 使用低体积加压腔使样品的压力达到所需的压力,这进一步提高了系统的生产率。 在采样台中设置透明体,因此用户可以在采样过程中观察样品。 反冲洗过程用于清洗样品注射管和样品吸收管。 此外,洗涤台被设计成冲洗样品吸收管的外表面。
