For years, there are requirements for high-precision continuous material dosing in the fields of precision spraying, cell culture, drug delivery, chemical synthesis, food additives adding, etc. Numerous pump products are existed in the market, however, each of them has its own problems in the above-mentioned application fields: For the piston pump, every piston movement creates a pulsation; Peristaltic pumps have the same problem, and when the pipes are worn, the flow rate will decrease and won’t be able to keep constant for a long time; Early traditional laboratory syringe pumps were unable to continuously deliver precise and accurate fluids for a long time due to limitations in syringe size; Later, in response to this problem, a bidirectional push-pull injection pump emerged, which solved the problem of unable to continuously transport fluid, but still unable to maintain flow stability for a long time, causing interruptions, especially in certain laboratory application fields, which couldn’t meet the needs of use.In order to meet such market demand and solve user pain points, Constinfuse® Constant Flow Syringe Pump, which is also called CFSP-I pump has been developed by the R&D Team of DK Infusetek. It truly allows the liquid to be delivered stably, accurately and continuously, with a flow rate range for water quality fluids from 0.06 μL/min to 70mL/min, the accuracy is less than ±0.05%, and the maximum pressure can reach 2 Mpa. CFSP-I Constant Flow Syringe Pump helps you achieve for more in your experiments or producing process. Welcome inquiry, and look forward to your feedback so that we could have the opportunity to continuously meet your needs.
1. Plug in and turn on Automated Lateral Flow Reagent Dispenser (ALFRD) unit and external syringe pump.2. Program syringe pump flow rate according to manufacturer’s instructions. a. See Figures 2 and 3 in Appendix A for recommended flow rates. b. ClaremontBio recommends using DK INFUSETEK SPLab/ISPLab Series Syringe Pump. 3. Select voltage on power supply. A range of 4.5 – 6V is recommended. a. If a faster head speed is desired, a power supply can connected in lieu of the provided power supply; However, 12V is the maximum voltage that can be used for the ALFRD. Figure 1. Voltage dependence on head speed: Voltage of ALFRD varied from 0 to 12V. Distance travelled = 30 cm.4. Secure dispense tips into desired placement slot on dispense tip head using provided Allen wrench. a. For best results, position tips very close to the membrane surface, without direct contact (unless contact is desired). i. Actual height is dependent on membrane type and thickness. b. Tips positioned too high may result in liquid droplet formation or uneven lines. c. To test positioning, place membrane on dispense table and initiate switch to cause table to move. Drag on membrane will be apparent. i. Once desired height is established, it may be helpful to mark position on metal post of dispense tip with a permanent marker.5. Once dispense reagents have been prepared, remove air bubbles prior to use in ALFRD (i.e. quick centrifugation, nitrogen air purge). a. A volume of 200 µl or greater is recommended. b. When solution is running out during dispensing, lines will appear thinner and may produce varying results. 6. Draw up each solution into a syringe, taking care to minimize air bubbles.7. Attach tubing to blunt syringe needle and secure filled syringes on syringe pump according to manufacturer’s instructions.8. Turn on syringe pump to prime solution(s) through tubing and dispense. Turn off pump and wipe away residual liquid.9. Secure membrane onto ALFRD dispense table using magnets.10. Turn on syringe pump, followed immediately by dispense table switch.11. Once dispense tips have reached the end of the table and stopped, turn off the pump.12. Remove membrane from table.13. Return dispense tips to their original position by reversing the table switch.14. Wipe off any residual liquid from table.15. Repeat for each membrane as necessary.
