masterflex hose type?

[ckoral]

I have a masterflex 7021-26 and I am having troubles learning about what type of tube to use on it. Also if and where a check valve should be.

You do not need a check valve as this is a peristaltic pump, it will not siphon back.

As far as tubing, that's a tough question. I personally am just using the "silicone tubing, L/S 13" because it is cheaper. You can get 25 ft for $30 straight from Cole-Parmer. In a perfect world I would probably order the food grade stuff.

Don't run just any tubing in the pump. If you are using this dose chemicals, this is even more important IMO.

could you link me to exactly what you have been getting becuase the stuff I pull up just seems wrong.

you can use ls 15 or ls 24 tubing. i use the pharmed but only because i have to. do some homework to see what are some other acceptable tubing options if you want to find some cheaper or more reliable tubing.

also, tellyfish. where do you get your tubing from? i use ls13 and there arent many options for tubing. i had to use the above because its the only size in ls13 edit========= oops, re read you get it from cole palmer.

I'm so glad I found this thread.
I've been looking on ebay for a good peristaltic pump but I'm not sure on which model number I should be looking for and which head unit.

I want to use this pump to feed my Calcium reactor so variable speed is a must I imagine. Other than that, I don't need all the bells and whistles I just need it to be quite and reliable.
