Delivering a best-in-class Flow Resistance Factor (FRF) or KR value, the LoKr is designed to improve process performance and efficiency. The highly engineered bursting disc design covers the majority of pressures in bioprocesses and enhances performance with the long-cycle life and tight tolerances of a reverse buckling rupture disc.

The disc’s architecture has been refined and optimized to offer full-bore opening with exceptionally accurate burst ratings. This supports operational efficiency, especially at low flow rates, and makes it easier to keep pressure drops across the relief line below 3%.
