Product description

Precision syringe pump with digital control, 10 µl–60 ml syringe range, and 0.1 µl/hr to 423 ml/hr flow rate.

The KD Scientific KDS 100 Legacy Syringe Pump is a digitally controlled infusion pump engineered for precise fluid delivery in biotechnology, molecular diagnostics, and bioprocessing applications. Designed to accommodate syringes ranging from 10 µl to 60 ml, it supports a broad flow rate range from 0.1 µl/hr to 423 ml/hr, enabling fine-tuned dosing essential for gene editing workflows and synthetic biology research.

Key technical features include:

  • Digital control system with smooth, continuous operation for reliable experimental reproducibility
  • High-accuracy mechanism with ± <1% flow rate error to ensure precise volumetric delivery critical in molecular cloning and biopharmaceutical production pipelines
  • 7.5-step stepper motor paired with a 25:1 gearbox offering ½ microstepping increments, where each microstep advances the syringe plunger by 0.529 µm
  • Step rate adjustable between 0.0025 sec/µstep and 30 sec/µstep allowing precise control over infusion speed
  • Linear force output up to 20 lb (9 kg), suitable for viscous fluids in biomedical engineering
  • Compact form factor with dimensions 22 x 10 x 6 inches and weight of 10 lbs, optimized for benchtop laboratory use in clinical diagnostics and live-cell imaging workflows
  • Power specifications: 100-120V, 50/60 Hz, 0.25A

This syringe pump is widely adopted in synthetic biology research and is essential for controlled reagent dispensing in biomanufacturing settings. Its robust design makes it a reliable tool in experimental setups requiring stable and accurate fluid handling for fluorescence analysis, neuroimaging sample preparation, and other advanced laboratory techniques.

Included components:

  • Fisher Scientific Single Syringe Infusion Pump (CAT# 78-0100I)
  • 120V Power Cord (1A)
  • Standard 30-day warranty

The KDS 100 Legacy Syringe Pump represents a critical instrument for researchers and laboratory professionals focused on biotechnology and clinical research requiring steady, programmable fluid infusion with microstep precision.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
