For the lab pros running demanding GC or GC/MS applications: Hamilton's BTO (Bleed and Temperature Optimized) septa are formulated to perform. These 10mm diameter, 3mm thick septa are designed for the lowest possible bleed at high operating temperatures – we're talking up to 400°C. That's crucial for trace analysis and when septa bleed can mess with your mass spec results. The 'Center Guide' design makes needle penetration smoother and requires less force, which can help reduce coring and tearing to extend septum life. This pack gives you 50 septa, which is perfect for manual injection applications. If you need reliable, low-bleed performance for your high-temp methods, these Hamilton septa are a lab staple you can count on.
