Sartorius Optifit Low Retention Tip Refill Tower – 0.1–10 µL, Non-Sterile, 960/Pack

If you're working with expensive reagents or detergent-heavy liquids, you know how annoying it is when sample sticks to the tip.

These Sartorius Optifit low retention tips solve that problem.

They've got a super-slick, durable liquid-repellent surface that makes even low-surface-tension liquids slide right off, so you recover more of your sample and waste less.
They also come in a refill tower format, which is super convenient for lab workflow—easy to grab and go.

This pack gives you 960 tips in the 0.

1–10 µL size, non-sterile, perfect for routine lab work.

Plus they're made in the USA.

Great for multi-dispensing, reducing cross-contamination risk, and general pipetting where every drop counts.
