The InsituPro VSi is INTAVIS’ next generation instrument for automated in situ hybridization and immunohistochemistry – it represents the third generation of the InsituPro product line. The InsituPro VSi maintains the flexibility and versatility of the InsituPro VS but additionally features a number of functions often requested by our customers such as a buffer preheating for posthybridization washes and more flexibility in temperature setting due to direct software control of the thermoregulator.
