Peristaltic Pump Tubing
The standard pump tubing is 5/8" OD (16 mm) medical grade silicone, which attaches easily to 1/2" OD (13 mm) downhole tubing. An adaptor kit, which allows the use of 3/8" OD (10 mm) tubing, provides lower sampling rates. This tubing attaches easily to 1/4" OD (6 mm) down-hole tubing.
To provide high sample integrity, the sample comes in contact only with the tubing. Replacing the tubing between locations avoids the possibility of cross-contamination. To reduce lengthy decontamination procedures, simply dedicate the inexpensive down-hole tubing.
Peristaltic Pump Sampling Rates
The Model 410 Peristaltic Pump has variable pumping rates, using two different sizes of silicone pump head tubing. With the standard 5/8" OD (16 mm) tubing it delivers 3.2 L/min.
The 3/8" OD (10 mm) tubing adaptor kit allows a sample rate as low as 40 ml/min. This low rate is ideal for low-flow sampling and the filling of small sample bottles.
The Peristaltic Pump's reverse action is ideal for back flushing when using the Drive-Point Profiler (see Model 660 Drive-Point Profiler data sheet).
