Hi, I am from India and we are interested in buying a peristaltic pump for patch clamp experiment. Can anyone suggest which one would be better from P-70 or P-1500 (Harvard)? Important consideration for us is that it should give least possible mechanical and electrical noise
Hi, Bhupesh!
The flow rate of P-70 is better suited for most path-clamp applications.
You can also consider peristaltic pumps by Longerpump.
Dmitry is right, the p-70 is better suited. But my word is that over engineered. Do you really want to deal with a touch screen when you just want your fluid to flow? The best pump I ever used was a Watson-Marlow Sci-Q 403U/VM . But I don't think they make it anymore. It was whisper quiet, electrically and audibly. However, a few places claim to still sell it, so I'd look into it.
Watson Marlow claim that their 100 series is the replacement for the Sci-q, but I can't comment on it. Still, if I were in the market for a pump, I'd see if I could get a demo.
Also, the Gilson Minipuls 3 is a pretty nice pump.
Finally, I would consider buying a cheap 12V motor and pump head like you can find on ebay. They are basically free. You just need to buy a 12V DC supply. They probably wont last forever, but given their price, it might be worth looking at.
If you don't really need a fancy control unit and multiple channels than a couple of these cheep pumps (one for inlet and one for outlet) can get the job done just fine: https://www.longerpump.com/index.php/BasicType/show/11.html
