Smooth-flo PDS100 System

Helps eliminate pulsation

Fluid Metering Inc, Syosset, NY, introduces its new Smooth-flo PDS100 System, a valveless dispensing and metering system that utilizes dual fluid metering pumps precisely synchronized to eliminate pulsation. Pump heads are integrally mounted to the control unit, which includes stepper motors, drivers, and programmable electronics housed in a rugged anodized aluminum enclosure. The intuitive, menu-driven device uses front-panel membrane switches and a large LCD display for programming. The system features fluid delivery down to 15 uL/min continuous flow. The system also offers RS485, 4-20 mA, 0-5V, and 0-10 V electronic control interface for connection to process sensors, PLC, and PC control systems.

StatSpin CytoFuge 12

12-place compact cytocentrifuge

The new StatSpin® CytoFuge 12, from Iris Sample Processing, Westwood, Mass, is a compact, low-cost cytocentrifuge, operating from 200 to 2,000 rpm, that concentrates up to 12 samples and gently deposits cells in a monolayer onto microscope slides for a variety of cell preparations. For safety, the unit operates only when the outer lid is locked. Inside is a removable sealed rotor that can be loaded in a hood to eliminate exposure to biohazards and can be autoclaved. Samples from 50 µL up to 800 µL are processed with snap-seal filter concentrators in consumable and reusable formats.
