buy with confidence guys, his frags are not nubs, these are actual frags that you can see the color and kind very clearly, bought many from him, love dealing with him every time,
I have watson marlow 520 as well where I can control the speed, size is just too big, I have few cole parmers as well the older styles where I can control the speed and rotation with solid state controller, but size on those is big as well,
Hello MR,
As the title says, looking to buy two continuous duty peristaltic pump that has control knob to control the speed,
Thank you in advance,
Ravi
