Abstract

Constant pressure pumps are an invaluable yet underutilized resource for microfluidic flow systems. In particular, constant pressure pumps are able to stabilize the fluid pressure in systems where the viscosity may change due to chemical reactions or the flow rate may vary due to deformations of the channels. The constant pressure pump presented here is designed on the premise of creating and maintaining a pressure differential between the laboratory and a pressure reservoir. This pressure reservoir is then used to drive the input fluid at the specified gauge pressure. The pump design presented here is perfect for primarily undergraduate institutions and other laboratories with modest research budgets as it can be built for under US$100 and construction is within the scope of an advanced undergraduate. The pump consists of an Arduino-compatible microcontroller, Adafruit electronic components, low-voltage air pump, Nalgene water bottle, and various fluid components. A complete parts list is included in the appendix. Comparable commercial pumps have a retail price in excess of US$5000. Multiple pump designs were constructed and tested with the ability to hold a constant pressure of up to 14 psig (97 kPa-gauge) with a maximum flow rate of 65 \(\upmu \)L/s for water.

基于Arduino的恒压流体泵

摘要

恒压泵是微流系统的宝贵资源,但未得到充分利用。特别地,恒压泵能够稳定系统中的流体压力,在该系统中,粘度可能由于化学反应而改变,或者流速可能由于通道的变形而改变。这里介绍的恒压泵是在建立和维持实验室与压力容器之间的压差的前提下设计的。然后,使用该压力储存器以指定的表压驱动输入流体。此处介绍的泵设计非常适合预算有限的主要本科院校和其他实验室,因为它的价格可以在100美元以下,并且在高级本科生的能力范围内。该泵由兼容Arduino的微控制器,Adafruit电子组件,低压气泵,Nalgene水瓶和各种流体组件组成。完整的零件清单包含在附录中。可比的商用泵零售价超过5000美元。构造并测试了多台泵的设计,它们能够保持最高14 psig(97 kPa表压)的恒定压力,最大流量为65\(\ upmu \) L / s的水。
