Filter Tips

Filter tips are used similarly to pipette tips, attaching to the end of a micropipette for use. They contain an embedded filter inside, preventing contamination of the micropipette body due to over-aspiration from operator errors or aerosols drawn in, which could contaminate other samples. Especially recommended are the fine-pore Hyper Filter types, which provide more reliable prevention against contamination. Since they use the same tips as pipette tips, empty racks in system racks can also be used interchangeably.

The features of the Watson Tip System

SYSTEM RACK (PC) Tough and extremely durable

The body and lid, made of polycarbonate (PC), does not lose its shape over time use. It can also be autoclaved repetitively. Note: Repeated autoclaving may cause rack damaged.

SYSTEM RACK(PP) Low cost and high chemical resistant

The body and lid, made of Polypropylene (PP), are lightweight, durable, and highly resistant to chemicals and heat. Due to its lower cost compared to the System Rack (PC), this System Rack (PP) can be disposed of after a single use or can be reused even after autoclaving if tips are manually refilled. Note: The rack made of PP shrinks slightly after autoclaving, consequently refill plate cannot be used.

REFILL PLATE Easy, Handy, and Eco-Friendly

One-touch replacement for the System Rack. The paper cover can be recycled. Note: Use a PC (polycarbonate) rack when refilling tips.
