World Precision Instrument Affordable High Performance Peristaltic Pump-PERIPRO-8LS
Peri-Star Pro peristaltic pumps provide accurate and precise pumping with convenience and versatility. Peri-Star Pro can be run in either flow rate mode (mL/min) or rotation speed mode (rpm). For good laboratory practice, pumps must be calibrated after changing the tubing and solution. You can easily calibrate Peri-Star Pro to deliver flow as accurate as 0.5% in a wide flow range from 0.1 - 280 mL/min. Under rotation speed mode, the digitally controlled stepping motor provides accurate and reproducible operation with 0.1% rpm both forward and in reverse.
AVANTOR MASTERFLEX (VWR LLC) Kobold PSR-5115 Flow Switch, Brass 1.3-2.1/1.0-2.0 GPM Increase/Decrease
The device operates as follows: The flowing medium presses against the paddle for the flow switch. The paddle is fitted to one end of a balance arm which is in direct contact with a prestressed leaf spring. At the other end of the balance arm is a permanent magnet. This magnet actuates a reed contact located within a moveable housing outside the media. The reed contact switches on or off depending on the position of the permanent magnet and the switch housing. The status of the switch may then be used to electrically control the fluid flow. The moveable reed switch on the unit allows the contacts to be set either normally open (N/O) or normally closed (N/C). FEATURES
- Switch point adjustable
- Easy to install
- Brass or SS construction
- Maximum pressure: 1450/3600 PSI
