Spectra Field-Pro Peristaltic Pump

Spectra Field-Pro peristaltic pump


The Spectra Field-Pro is a state-of-the-art peristaltic pump that features a heavy-duty, all-inclusive design. This means no external cables,chargers or batteries to worry about.


Weighing in at 29lbs/13 kg (including the battery), the Spectra Field-Pro’s powder coated aluminum case has heavy duty latches, hinges and handle.

The case has a built in storage compartment which can hold a field book as well as the two power cables that come with the Field-Pro.

The case also incorporates a stand for sample bottles. A rubber gasket around the inside of the case lid helps keep the elements out while it’s closed.

The Masterflex EasyLoad II pump head is the best available – especially for environmental work. The peristaltic tubing is simply placed into the pump head channel and the head is then closed by moving the lever over to the opposite position. Next, sample tubing is attached to the peristaltic tube and the unit may be turned on.

Thermoplastic Elastomer (TPE)

Thermoplastic Elastomer (TPE) is a soft and flexible polymer with excellent physical properties, making it a good alternative for silicone tubing in peristaltic pumps. Waterra stocks tubing sizes L/S 15 and L/S 24 for use in the Spectra Field-Pro Peristaltic Pump.

TPE tubing is stocked in 25 foot coils.
