The cell–medical biomaterial stress–electrostatic co-culture system supports co-culture under multiple electrostatic modes and related parameter detection, enabling evaluation of medical biomaterial biocompatibility and material properties.

Cell–Medical Biomaterial Mechanical-Stress and Electrostatic Co-culture SystemEnables co-culture of cells and medical biomaterials under multimodal stress–electrostatic conditions and measurement of related parameters, allowing evaluation of cell–medical biomaterial biocompatibility and various material properties.

1、Cell–Medical Biomaterial Mechanical-Stress and Electrostatic Co-culture SystemMain functions:

(1) Culture-chamber design features: convenient positioning and clamping; a sterilizable sealing component at the moving end; a rational, safe electrostatic-circuit layout; easy sample installation and removal; and convenient medium replacement;

(2) After power is disconnected, the loading unit remains in place rather than descending under gravity;

(3) The culture chamber and stress-loading device are located inside the incubator, while the control system is outside for convenient parameter settings;

(4) Measures pressure parameters and frequency, displays real-time curves, stores data, and permits instrument adjustment for convenient operation;

(5) Each culture unit cultures one material sample. Each dynamic culture unit can be installed, removed, and relocated as needed and placed in a 5% CO2, 37℃ constant-temperature incubator. Cell scaffolds can be inserted and removed and medium replaced easily, with a low risk of contamination;

(6) Each dynamic culture unit is sealed and maintains suitable pH and carbon-dioxide concentration;

(7) The entire bioreactor is reusable and can be sterilized by acid washing and alcohol fumigation, but not by high-temperature, high-pressure sterilization;

(8) Material deformation: 0–40%.

2. Technical parameters:

(1) Material dimensions: 20 × 20 mm;

(2) Material thickness: 0.5–2 mm;

(3) Displacement: 0–15 mm;

(4) Number of culture chambers: 12;

(5) Instrument dimensions: 350 × 400 × 400 mm;

(6) Required tension and deformation: 0.1–100 N; deformation: 0–20%;

(7) Frequency: 0.1–2 Hz; cyclic stress can be applied intermittently or continuously without interruption;

(8) Material-clamping position: the material is electrically connected at the clamp, ensuring that the electrode does not contact the culture medium.

3. This product has received a Chinese invention patent grant:patentNo. ZL200710043013.7.

4. After-sales service and training:

(1) Free delivery to the user's address and free on-site installation and commissioning. From the date on which installation and commissioning pass user acceptance, the warranty period is one year, with all repairs free during the warranty period.

(2) During on-site installation and commissioning, technical staff train operators, with no limit on the number of trainees, until users can operate and perform routine maintenance independently.

(3) Repair response time ≤2 hours; proposed solution ≤24 hours; on-site technical support ≤48 hours.
