Welcome to Takasago Electric, Inc., a leading manufacturer of valves, pumps and manifolds
Electro-osmotic Pumps
By utilizing electro-osmotic flow, this pump provides a pulsation-free flow of alcohol or de-ionized water. Continuous pumping in microfluidic volumes can be achieved without creating pulsation. No noise is generated by the pump, and high pressure performance is possible.
*For more information on the pumping principle, please see here.
*For the demonstration video, please see here.
A system including a power source and a flow sensor is also available, and can provide stable microfluidic flow. For more information, please contact us.
List of Electro-osmotic Pumps
LFHP Series
Despite the compact size, a high pressure performance can be achieved due to the use of improved electro-osmotic material. These pumps are designed for generating a stable flow of 1 μL/min or less.
| Maximum Flow Rate | 8μl/min. |
|---|---|
| Maximum Pressure | 2000kPa |
| Outer Dimensions | φ10.3 x 27.3mm |
RP3 Series
These miniature pumps are suitable for pumping de-ionized water. Two options for the length of the nozzle are available.
| Maximum Flow Rate | 10μl/min. |
|---|---|
| Maximum Pressure | 90kPa |
| Outer Dimensions | φ6.0 x 13～13.7mm |
RP5A-RL Series
These miniature pumps are suitable for pumping de-ionized water and alcohol. In addition to the reservoir type, a pump with a self-priming structure* is also available.
| Maximum Flow Rate | 110 ～ 190 μl/min. |
|---|---|
| Maximum Pressure | 110 ～ 140 kPa |
| Outer Dimensions | φ8.0 x 20.4mm |
RP20-SP Series
This pump is suitable for pumping alcohol. It is the largest of our electro-osmotic pumps. The pump has a self-priming structure (a self-priming bar)*.
| Maximum Flow Rate | 830μl/min. |
|---|---|
| Maximum Pressure | 95kPa |
| Outer Dimensions | φ27.0 x 25.3mm (Body) |
| ※ | The self-priming structure uses a self-priming bar instead of a reservoir and can provide a continuous supply of liquid by setting a pump in the middle of the plumbing. |
