The micro needle strength tester is mainly applicable to the strength measurement of prismatic silicon micro needle, solid micro needle, hollow micro needle, metal micro needle, polymer micro needle, ceramic nano micro needle, hydrogel micro needle, hyaluronic acid micro needle, etc. It can also be used to accurately determine the mechanical properties of fine products such as microspheres, microcapsules, and hydrogel particles. This machine is also known as a texture analyzer, microneedle strength tester, microneedle tester, microneedle strength tester, microneedle backing compressive strength tester, and microneedle puncture transdermal performance tester.
Micro needle refers to a needle like structure made through micro processing technology, with a diameter of 30-80Lm and a length of over 100Lm, with dimensions in the micrometer range; Microneedle is an efficient, safe, and novel transdermal drug delivery technology, which has advantages that other traditional transdermal drug delivery technologies cannot achieve. Microneedles have broken down a major barrier in transdermal drug delivery - the blockade of drugs by the stratum corneum, not only greatly improving drug delivery efficiency, but also making transdermal delivery of macromolecular and hydrophilic drugs possible. Microneedles are widely used in cosmetics, eye care, diabetes, cancer and biomedicine, such as local anesthesia, immunization, micro sampling, DNA administration, skin beauty, protein and peptide drug delivery. Materials can be silicon, polymers, metals, etc.
The mechanical properties of microneedles have a significant impact on their drug delivery efficiency. The microneedle strength tester can accurately measure mechanical indicators such as microneedle strength.
Test items for microneedle strength tester:
Micro needle fracture strength; Micro needle fixed deformation, testing force value; Set the force value and measure the deformation.
Features of microneedle strength tester:
1. The touch screen display displays real-time force values, displacement deformation, fully automatic testing, and automatically saves the maximum value of the current test; The display interface can display the test curve in real time; Test real-time parameters such as speed and deformation.
2. Using a high-precision, fully digital speed control system and precision reducer, the precision screw pair is driven for testing, achieving a wide range of adjustment of the test speed and smooth operation.
3. Adopting high-precision sensors and professional measurement and control software, with high testing accuracy, wide testing range, and simple operation.
4. Equipped with a standard micro printer, it can print results at any time and can calculate multiple test results, maximum, minimum, and average values.
5. After selecting computer control, the software that synchronously displays test data, force, time, distance, etc. during the testing process; The experimental data is stored in text files for convenient user queries, as well as for reprocessing the experimental data using reports and processing software, while also facilitating the transmission of data through the internet; It is also possible to perform comparative analysis of data by stacking any group of curves; Can store data infinitely and print A4 reports; Can achieve timely upgrading of operating software functions and increase experimental projects.
