A cerebrospinal fluid pulsation bioreactor is advanced laboratory equipment for biological and medical research. It simulates physiological conditions such as cerebrospinal fluid pulsation to provide cells or tissues with culture conditions close to the in vivo environment. Its basic principle is to culture cells or tissues on a gas-permeable, porous, elastic artificial matrix and promote their growth and development through simulated physiological stimuli such as joint movement, pressure, and fluid shear. This simulation helps study cell behavior under specific physiological conditions and mechanisms of disease onset and progression. Detailed structural description: 1. Main control box: the control center of the entire reactor, responsible for setting and controlling mechanical-environment parameters in the culture chamber...

A fully automated exosome extraction and concentration instrument is advanced biological laboratory equipment used primarily for efficient, automated extraction and concentration of exosomes from biological samples. It uses technologies including pulsed tangential-flow multistage recirculating filtration, intelligent control, and magnetic-bead capture. Pulsed tangential-flow constant-pressure multistage recirculating filtration prevents particles from clogging the membrane and continuously processes large sample volumes rapidly, while magnetic-bead capture specifically binds exosomes for efficient separation and extraction. Structural categories: 1. Reservoir. Conical-bottom design: the reservoir has a conical bottom so even trace sample at the bottom can be processed. This prevents sample waste and improves equipment utilization eff...

Cell adhesion is a key interaction between cells and their surrounding environment and is essential to biological functions such as migration, proliferation, and signal transduction. Measuring and understanding adhesion forces is therefore important to studying cell behavior and physiological processes. Recent advances in cell adhesion force measuring instruments have provided powerful tools for this field. Such instruments are generally based on microfluidic mechanics and measure adhesion between cells and a substrate by applying controlled shear force or pressure. Common methods include traction force microscopy, magnetic bead traction, and microfluidic chips. Combined with image processing and mechanical analysis, these technologies monitor and quantitatively assess cell–substrate adhesion in real time. Applications: 1....

A quantitative corneal transparency meter is specialized equipment for precise measurement of corneal transparency. It works primarily by detecting changes in laser illumination after the beam passes through a medium due to absorption by that medium. When light passes through the cornea, transparency affects transmittance and scattering. By measuring these optical parameters, the instrument calculates a corneal transparency value. Detailed operating steps: 1. Preparation: ensure that the device is connected to power and switched on. Check the display and control panel and ensure that all display and control functions operate normally. Prepare accessories such as the measurement head and eye mask. 2. Patient preparation: seat the patient in front of the device and ensure correct positioning of the head and eyes. If necessary,...
