Coulter S Plus IV

This is a used Coulter S Plus IV automated hematology analyzer, part of the well known Coulter S Plus family that helped define electronic impedance based blood cell counting for decades of laboratory use. It measures red cell, white cell, and platelet counts along with hemoglobin and derived indices, giving technicians the core data needed for routine CBC testing. The unit is offered here in used condition for labs and collectors who value the reliability of this classic Coulter platform. Built on the Coulter principle of electrical impedance counting, the S Plus IV was engineered for consistent, repeatable results in high volume clinical settings, and many of these systems remained in service for years due to their mechanical durability. It supports standard sample processing workflows familiar to techs trained on Coulter equipment, and its straightforward electromechanical design makes it a relatively serviceable unit compared to more complex modern systems. Labs that already run Coulter reagents and calibration procedures will find it fits directly into existing protocols. This analyzer suits smaller clinical laboratories, teaching labs, veterinary practices, and facilities that want a dependable legacy CBC counter at a fraction of the cost of new equipment. It is also a good option for backup or overflow testing capacity, or for training environments where a rugged, well understood analyzer is preferred over the added complexity of current generation platforms.
