Pipette Tips

Pipette tips are disposable components attached to the tip of a micropipette, used to hold and transfer aspirated liquid samples. These tips are available not only in bulk packaging where only the tips are packed in bags but also in the form of “system racks” where pipette tips are pre-loaded into racks for ease of use. “Pre-sterilized system racks” are designed with consideration for contamination prevention, eliminating the need for autoclaving and allowing for immediate use. Additionally, products such as “refill plates” and “stack racks” are available separately for easy replenishment of pipette tips for these system racks, offering further convenience through combination use.

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.

How to refill the Refill Plate.

Remove the old plate.

Place the new plate. Remove paper skirt.
