1200μl barrier xTIP4 pipette tips are compatible with Rainin™ LTS™ pipets. Each tip features four patented technologies designed to create the ultimate pipetting experience. StarStop? technology features a positive stop that reduces the amount of force needed to create the perfect seal every time. Patented FlexFit? technology reduces the tip’s insertion and ejection forces, which can help reduce the risk of repetitive strain injuries. Our proprietary ultra-low retention X-Resin? minimizes the binding of DNA and protein samples and outperforms competing tips with postproduction low-binding treatments. Blade? technology eliminates hanging droplet formation and the need for “tip touch off”.

All xTIP4 pipette tips meet the industry’s most rigorous quality control standards. They are 100% virgin polypropylene and are free of recycled, reprocessed, or altered plastics that can introduce contamination and defects. Our pipet tips are chemically inert and not affected by common laboratory solvents, including chloroform, chloroethane and acetone.
