Micro Needle Valve

Product catalog summary

Introduction
The document provides technical details about the MNV Series Micro Needle Valve by Takasago Electric, Inc., designed for precise flow control in microfluidic applications.

Features

Allows fine manual adjustment of flows below 1 μl/min.
Reduces flow pulsation by restricting flow.
Constructed with wetted materials including Perfluoroelastomer, PEEK, and stainless steel.
Operates within a pressure range of 0 to 200 kPa.

Note: Specifications are subject to change without notice.

Flow Characteristics
The document includes a flow-graduation relationship graph, indicating that flow characteristics vary according to the valve used. An example flow data graph is provided for water at 10 kPa.

Reduction of Flow Pulsation
Piezoelectric micro pumps, when used alone, can transfer flows at μl/min levels but may cause significant pulsation. By integrating a micro needle valve on the discharge side, pulsation is significantly reduced, as demonstrated by a comparison graph. This setup is effective with other pump types, such as peristaltic pumps.

Low Pulsation Micro Pump Module
This module adjusts the flow of a piezoelectric micro pump at the μl/min level using a micro needle valve. It is suitable for applications in fields like flow cytometry and cell culture equipment. The document includes a setup example with a piezoelectric micro pump, micro needle valve, and micro flowmeter.

Réduction of Flow Pulsation <Example of Combination with Piezoelectric Micro Pump> Piezoelectric micro pumps are small-sized, lightweight and slim diaphragm micro pumps driven by piezoelectric élément. By considerably reducing the drive frequency and the drive voltage from the standard operating ranges, a piezoelectric micro pump alone can transfer |j|/min level flows. However, significant pulsation is created at a low flow rate as represented by the blue line in the graph below. By incorporating a micro needle valve on the discharging side of a piezoelectric micro pump, a low flow rate with...
