Hydrogel viscosity tester

In the biomedical materials and adhesive industry, it is very important to accurately characterize the adhesion performance of soft materials such as hydrogels. Jinan Xio Electromechanical relies on its profound background in material testing technology to launch a specializedHydrogel viscosity testerCommitted to providing stable and accurate initial adhesion quantification solutions for the industry. This instrument strictly follows the physical testing method of contact separation, and provides key data support for product development, quality control, and standard compliance verification by simulating the adhesion and peeling behavior of materials in practical applications.

Core Features

This instrument integrates high-precision measurement, intelligent operation, and strong adaptability. Its core advantages are reflected in:

• Accurate adhesion quantification ability: The instrument adopts imported high-precision force value sensor and stable PLC motion control system, with measurement accuracy up to ± 0.5%, which can sensitively capture the tiny initial viscosity change of hydrogel, and ensure the repeatability and reproducibility of test results.

• Professional pressure head testing principleStrictly follow the Probe Tack Test method and come standard with a 5mm diameter precision ground plane probe. The probe can be precisely controlled to contact the sample at a constant speed, maintain a preset pressure and time, and then separate at a uniform speed in reverse, directly measuring the maximum separation force, that is, the initial adhesion force. The principle is scientific and intuitive.

• Intelligent interaction and efficient operationEquipped with a 7-inch high-definition touch screen (HMI), users can intuitively set parameters such as test speed, contact time, trigger force, and observe test curves in real time. Equipped with automatic reset function of measuring head and built-in micro printer, it greatly improves the efficiency and convenience of batch testing.

• **Speed control and scalabilityThe testing speed is infinitely adjustable within the range of 1-500mm/min, meeting the requirements of different standards or internal methods. By replacing probes of different specifications or materials and customizing specialized fixtures, it can be easily extended to viscosity testing of other pressure-sensitive adhesives, medical tie agents, or soft materials.

• Comprehensive data management capabilitiesThe system automatically records and saves the peak force values and curves of each test, supports data query, comparison, and analysis, and can directly output test reports through a printer for quality traceability and analysis.

Test Principle

This device is based on the classic Probe Tack Testing principle. During the test, the precision plane probe descends vertically at a constant speed under the program control, contacts the hydrogel sample surface below and applies a constant preset pressure. After the set holding time, the probe separates vertically upwards at a constant speed. Throughout the entire process, the force sensor continuously monitors and records the required force value for the separation stage, with the maximum value being the initial adhesion force (initial adhesion force) of the sample. This method can effectively simulate the adhesion behavior of materials in the early stages of use, with direct and reliable data.
