Abstract
An electrochemical sensor with a capillary channel is formed by placing a sacrificial insert and electrodes on a sensor base and applying plastic material. After the plastic material is cured, the sacrificial is removed leaving a capillary channel in the sensor. The inserts may be removed by a tool including a clamp for clamping and holding each insert stationary and a sliding block to which the sensor is secured.
Claims17
A method of molding an electrochemical sensor, the method comprising the acts of:
- providing a first mold;
- inserting a first electrical contact in the first mold;
- inserting a second electrical contact in the first mold;
- placing a sacrificial insert in the first mold;
- closing the first mold with a second mold;
- injecting material for forming the electrochemical sensor into the closed first and second molds;
- curing the material;
- opening the first and second molds with respect to each other;
- and
- extracting the sacrificial insert from the cured material so as to leave a channel in the cured material and form the electrochemical sensor, the channel extending from a first end of the electrochemical sensor and terminating before a second end of the electrochemical sensor.
A method of forming an electrochemical sensor, the method comprising the acts of:
- providing a sensor base;
- placing a sacrificial insert on the sensor base;
- placing a first electrical contact and a second electrical contact on the sensor base, the sacrificial insert being positioned between the first electrical contact and the second electrical contact;
- placing plastic material on the sensor base and over the sacrificial insert;
- and
- removing the sacrificial insert from the plastic material and the sensor base leaving a capillary channel in the plastic material so as to form the electrochemical sensor, the capillary channel extending from a first end of the electrochemical sensor and terminating before a second end of the electrochemical sensor.
