Giá đỡ ống Falcon cho chai Schott 100 ml

This holder for 15 ml Falcon tubes snaps onto 100 ml Schott-style bottles for handy storage of pasteur pipettes for the solution in the bottle.

It's intended use is for bottles containing solutions for pH adjustments, where it is much more economical to reuse the same pipet for one solution.

I recommend PETG for it's durability and elasticity.
