Watson Tip System

Tough & extremely durable

The body and lid, made of polycarbonate (PC), does not lose its shape over time use. It can also be autoclaved repetitively.

Low cost and high chemical resistant

The body and lid, made of Polypropylene (PP) is lightweight, durable, and highly resistant to chemicals and heat. Because of its inexpensive cost compared with System Rack (PC), this System Rack (PP) can be disposed as one time use if used with non-sterilized long tip, 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.
