• Model NRP-1000
• Compact model ideal for low flow rate applications
• Equipped with a rotation speed display for precise and quantitative operation
♦ Since only the tubing comes into contact with the liquid, there is no contact with metal parts, eliminating concerns about contamination.
Its integrated tubing case design enables easy tube replacement by simply lifting the tubing holder.
♦ The rapid-priming switch enables operation at the maximum flow rate, quickly filling the tubing path up to just before the dispensing point.
♦ Four types of tubing are available depending on the liquid being used: Silicone, PharMed®, Tygon®, and Versilon (Fulran®). Each type comes in three different inner diameters. Select the appropriate tubing based on the liquid type and required flow rate.
• Characteristics
• Clear display and excellent operability
The rotation speed is displayed digitally, allowing for precise and consistent setting of operating conditions.
• Discharge volume can be adjusted via external signal input
Equipped with an external signal input terminal for discharge volume control via electric signals (0 to 10VDC) from a PC or measurement device. This enables automation of reagent addition and other delivery systems.
• Each tubing case can be individually fixed at 90° increments
Aligning the suction and discharge ports in the same direction allows for optimal tubing length without unnecessary bends or kinks. (Different tubing sizes can be combined for each channel.)
• Leak detection using the optional leak sensor
If a tube ruptures inside the tubing case, causing leakage, the optional leak sensor set detects the leakage and stops the liquid delivery. Made of Teflon®, the leak sensor provides excellent chemical resistance.
