By spraying staining reagent onto tissue sections, diagnostic accuracy and reproducibility are both achieved.

Tissue sections have extremely fine structures, with subtle differences occurring at each site. Therefore, uniform application of staining reagents is essential to ensure the reliability of diagnosis and research. Conventional application equipment posed the following challenges:

• The coating is not uniform
  Existing devices had insufficient spray control, resulting in uneven staining for each tissue region and differences in staining reactions within the same section.
• Excessive reagent usage and reduced work efficiency
  Excessive reagent dispensing resulted in a lot of waste, which led to increased reagent costs and inefficient work.
• Impact on consistency of diagnostic and research results
  Due to inconsistent staining results, there were issues with the reproducibility and accuracy of test results.

The introduction of the “SV91 Spray Valve,” which enables high-precision spray control, and the “AXELIA Vision Dispense System,” which offers excellent visibility and automated precision, has resulted in the following benefits:

• Enables uniform and highly accurate spray application
  Micro-air control and nozzle air adjustment ensure a uniform mist spray without splashing, resulting in uniform distribution of reagents for consistent staining reactions within the tissue.
• Optimize reagent usage and reduce costs
  By accurately applying only the minimum amount required, the amount of reagent used was reduced, contributing to cost containment.
• Improved reliability of test results and work efficiency
  Consistent dispensing quality improves the reproducibility of test data, resulting in increased reliability and efficiency in medical and academic research.
