Genuine Magenta 2-Way Caps (1000pc)

Genuine Magenta® 2-Way Caps are an excellent solution for test-tube production of in vitro plants. The built in drip ring prevents condensation build up while minimizing contamination and the flexible ribs hold the cap snugly to the tube. High quality polypropylene plastic gives maximum life span, and a built in filter grove make it easy to add custom filters to the caps.
