The Sartorius Corporation 791211F Sterile Filter Tips can handle volumes from 50 to 1200 µL, based on what the manufacturer specifies. They're really great for molecular biology and other lab applications where you need precise measurements and no contamination.

A nice feature of these tips is their SafetySpace™ design. This gives you more room between the sample and the filter, which helps keep your sample from touching the filter and lowers the risk of contamination. It's pretty useful if you're doing detailed pipetting work.

The manufacturer describes these tips as specifically made to work smoothly with Biohit pipettes, ensuring high precision.

Plus, they've got an ergonomic design with something called Optiload to make it easier to attach and eject the tips—helpful for staying comfortable during repeated use, especially if you're using them with Sartorius eLINE, mLINE, and Proline Plus pipettes. They also fit most other pipettes, which is handy in case you're using a variety.

From our research, it seems that a lot of folks appreciate the filtration efficiency of these tips. They're good at minimizing sample loss and improving reliability in critical procedures. They're pre-sterilized and certified to be DNase, RNase, and endotoxin-free, adding an extra measure of safety for sensitive experiments.

These tips also use polyethylene filters that capture both solid and liquid aerosol particles without needing self-sealing additives. This not only protects your samples but also helps extend the time before you need to maintain your pipettes, which can be a smart choice for labs looking for high-quality pipetting solutions that keep contamination at bay.

In short, the Sartorius 791211F Filter Tips pack a lot of great features for labs that need precision and safety.
