Masterflex L/S Easy-Load II pump head
This upgraded version of the Easy Load pump head retains tubing safely in place with no manual adjustment. With its compact design and 4 rollers, it offers optimal use of space and low pulsatility.
- Designed for different sizes of tubing, from 0.001 to 2900 mL/min
- Compact for space-saving purposes
- Adjustable occlusion or open-head sensor option
- Stackable up to 4 pump heads (on compatible drives)
- Fixed occlusion (adjustable occlusion option available)
- Open-head sensor option
Compatible with Masterflex tubing:
- Standard: L/S 13, L/S 14, L/S 16, L/S 25, L/S 17, L/S 18
- High-performance: L/S 15, L/S 24, L/S 35, L/S 36
Materials
The pump head housing is made of polyphenylene sulfide (PPS) for protection against corrosive liquids and vapors. The rotor is available in two materials:
- plated cold-rolled steel (CRS) for general applications
- 300 stainless steel (SS) to resist more corrosive fluids
Options
The open-head sensor option automatically stops the motor when the pump head is opened to increase safety while working with the pump, provided that the drive is sensor-equipped.
The adjustable occlusion allows better control over the flow system. An increased occlusion maximizes pressure performance and a better suction lift, while a reduced occlusion extends tubing life.
