For applications that require quick tubing changes, providing easy changeovers with the touch of a lever that opens the occlusion bed and simultaneously retracts the tubing retainers
Barnant introduces the Masterflex L/S Easy-Load 3 pump head, with new automatic tubing retention for quick setup or changeover and featuring twist-lock mounting to mount single or multiple-stacked heads in seconds without tools or hardware.
Up to four L/S Easy-Load 3 heads can be stacked for increased flow capacity or multiple-channel applications, and a mounting plate adapts the new head to all Masterflex L/S drives.
L/S Easy-Load 3 pump heads are said to be ideal for applications that require quick tubing changes, providing simple and easy changeovers with the touch of a spring-loaded lever that opens the occlusion bed and simultaneously retracts the tubing retainers so tubing slips right in.
When the pump head is closed, the retainers automatically grip and securely hold tubing in place.
The occlusion bed applies optimal occlusion force to all accepted tubing sizes, and the head's wide occlusion angle prevents fluid backflow.
The new pump head is available in a precision tubing model that accepts all six L/S precision tubing sizes, for a total flow range of 0.06-2300ml/min, and a high-performance precision tubing model that accepts all four L/S high-performance precision tubing sizes for a total low range of 1.7-2900ml/min.
Its polypropylene housing offers chemical resistance, and ball bearings in the rotors reduce friction on tubing to improve tubing life.
The head is available with either cold-rolled steel rotors for economy or stainless steel rotors for durability and chemical resistance.
