The injection pump is a precision benchtop instrument designed for controlled fluid delivery in research applications requiring accurate volumetric dispensing. This programmable syringe pump accepts standard syringes from 5ml to 60ml and delivers volumes from 0.1ml to 9999.9ml with ±2% accuracy when properly calibrated. The system features RS-232 interface connectivity for computer control and data logging, with onboard storage for 2000 events that can be downloaded for analysis.
The pump incorporates Keep Vein Open (KVO) functionality with programmable rates from 0.1-5.0 ml/h and bolus delivery capability for volumes up to 50ml in 0.1ml increments. The Class I, Type CF, IP44 protection rating makes it suitable for laboratory environments where liquid handling precision is critical. The compact 240×150×117mm footprint and 2.0kg weight provide benchtop compatibility without consuming excessive workspace.
How It Works
The injection pump operates using a precision stepper motor-driven mechanism that advances and retracts a syringe plunger at programmable rates. The system calculates volumetric flow based on syringe diameter and linear displacement, converting rotational motor steps into precise fluid displacement. Internal sensors monitor plunger position to ensure accurate volume delivery within the specified ±2% tolerance when properly calibrated.
The programmable controller manages infusion parameters including flow rate, total volume, bolus delivery, and KVO maintenance rates. The RS-232 interface enables computer control and real-time monitoring, while onboard memory stores operational parameters and event logs. The system maintains consistent delivery pressure through controlled plunger advancement, suitable for applications requiring steady-state flow or precise bolus injections.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Volume Range | 0.1-9999.9ml with 0.1ml resolution | Entry-level pumps often limited to smaller volume ranges | Accommodates both microvolume precision work and large-scale fluid delivery in a single instrument |
| Syringe Compatibility | Standard 5-60ml syringes | Some models restricted to specific syringe brands or sizes | Uses readily available standard syringes reducing operational costs and inventory requirements |
| Data Storage | 2000 event log capacity with download | Basic models often lack data logging capabilities | Provides comprehensive protocol documentation for regulatory compliance and troubleshooting |
| Interface Options | RS-232 computer connectivity | Manual-only operation on simpler units | Enables automated protocols and integration with laboratory data management systems |
| KVO Functionality | Programmable 0.1-5.0 ml/h maintenance rates | Fixed or no KVO options on basic pumps | Maintains line patency during extended protocols without manual intervention |
This injection pump combines wide volume range capability with precision control and data logging features. The RS-232 interface and programmable KVO function provide automation capabilities often found only in higher-end laboratory pumps.
Practical Tips
Verify calibration using gravimetric measurement with water at room temperature for each syringe size used.
Why: Different syringe manufacturers have slight dimensional variations that affect volume accuracy calculations.
Flush system with appropriate solvent after each use and store with dry tubing to prevent contamination buildup.
Why: Residual fluids can crystallize or react, causing flow irregularities and accuracy degradation.
Prime tubing completely and check for air bubbles before starting programmed infusions.
Why: Air bubbles compress under pressure leading to delayed delivery and inaccurate flow rates.
Monitor back-pressure by observing consistent flow rates; erratic delivery may indicate tubing occlusion.
Why: Partial blockages increase system pressure and reduce flow accuracy before complete failure occurs.
Download event logs regularly and correlate with experimental protocols for comprehensive documentation.
Why: Historical pump data helps identify equipment drift and provides audit trails for regulated studies.
Use appropriate personal protective equipment and ensure pump placement prevents accidental contact with moving parts.
Why: The mechanical drive system and pressurized fluids present potential hazards during operation and maintenance.

Background reading relevant to this product:
What is the minimum detectable volume increment for precise microvolume applications?
The pump delivers volumes in 0.1ml steps across the entire range from 0.1ml to 9999.9ml, making 0.1ml the minimum programmable increment.
How frequently should the pump be calibrated to maintain ±2% accuracy?
Calibration frequency depends on usage patterns and critical application requirements; consult product datasheet for recommended calibration intervals based on volume throughput.
Can the RS-232 interface control all pump functions remotely?
The RS-232 interface enables computer control and data download, though specific command protocols and controllable parameters should be verified in the technical documentation.
What is the maximum back-pressure the pump can overcome?
Maximum operating pressure specifications are not provided in the basic specifications; consult product datasheet for pressure limits and flow rate dependencies.
How is the 2000-event data storage accessed and formatted?
Event data can be downloaded through the RS-232 interface, though specific file formats and data fields should be confirmed in the operational manual.
Does the KVO function automatically activate after programmed infusion completion?
The KVO rate is programmable from 0.1-5.0 ml/h, but specific automatic activation settings and protocols should be verified in the user documentation.
