FlexTop Low Force Pipet Tip Features

These pipet tips not only mount and eject with low force, they are made of clear pre-tested medical grade polypropylene and lot certified pure and free of DNase, RNase, ATP, and they are non-pyrogenic.

These tips are also available with aerosol filters and low retention versions. And they are also available in validated sterilized versions unlike the non-validated “pre-sterilized” product available from others. Moreover, every rack is labeled with the product number, production lot, recycling code, expiration date, and effective volume range of the tips inside.

FlexTop™ pipet tips make your pipetting experience better. This video shows proper technique when pipetting with FlexTop™ tips. You never need to "jam" or repeatedly "pound" your pipettor to fit these tips onto major brands of pipettors.

The Eclipse™ Pipet Tip Refill system from Labcon goes far beyond other reload systems to bring a complete refilling solution to your lab. With a simple lift, place, and snap, you can refill Labcon and other brands* of pipet tip racks with 18 different styles of tips. Eclipse™ refill tips are lab certified Rnase/Dnase, ATP free, and Non-Pyrogenic. Sterile refills use a validated sterile process and include an expiration date on every pack.

The Eclipse™ is a revolution in pipet tip refills. Far beyond simple recycle coding, the patent pending Eclipse™ is a completely designed system with a Low Carbon footprint that includes the first ever use of recyclable bio-plastic (non-petroleum) resin in pipet tip refills. And the Eclipse™ small footprint extends to the package, with a reclosable box that helps you maximize storage space in crowded labs.
