    WHY CHOOSE THIS PRODUCT

    Three reasons to invest

    • From unboxing to results in no time. Sigma Peak arrives pre-assembled with clear guidance, so you can go from unboxing to your first measurement in a few simple steps. Pre-defined measurement scripts together with automatic probe alignment and operation reduce decision making and let you focus on your samples.
    • One instrument for research and routine measurements. Run advanced R&D studies and routine quality checks on the same platform. The software handles complex force tensiometry methods, while the standalone mode delivers fast surface and interfacial tension measurements for everyday QC, all with consistent hardware and data handling.
    • No hidden costs. Durable hardware, minimal consumables, free software updates and the ability to serve several teams and applications give Sigma Peak high measurement capacity at a low cost of ownership.
