What is the most accurate reagent dispensing technology?

Positive displacement dispensing provides the highest accuracy and repeatability for precision reagent applications.

Can precision reagent dispensers handle viscous or volatile fluids?

Yes. Positive displacement systems are ideal for viscous, shear-sensitive, and volatile reagents because volume is mechanically controlled.

Are precision reagent dispensers used in OEM equipment?

Yes. Precision reagent dispensers are widely used in OEM analytical, diagnostic, and medical device systems.

Ultra-Accurate Liquid Dispensing Solutions by IVEK

What is a Precision Reagent Dispenser?

Precision reagent dispensers are engineered to deliver extremely accurate and repeatable reagent volumes, often in the microliter or sub-microliter range. These systems are critical in applications where consistency, contamination control, and exact dosing are required. IVEK precision reagent dispensers are built around positive displacement technology, ensuring consistent delivery regardless of fluid viscosity, volatility, or temperature.

What are Precision Reagent Dispensers Used for?

IVEK precision reagent dispensers are used in applications where manual pipetting or conventional pumps cannot meet accuracy and repeatability requirements. Common applications include:

Diagnostic reagent dispensing
In-Vitro Diagnostics
Lateral Flow Assay Manufacturing
Analytical instrumentation
Biotechnology and life science research
Medical device manufacturing
OEM integration for automated instruments

Why Choose an IVEK Precision Reagent Dispenser?

IVEK precision reagent dispensers are trusted worldwide because they deliver:

Superior accuracy and repeatability (>0.1%)
Zero particulate generation during dispense
Inert wetted components
No metallic fluid contact parts
No dynamic seals to abrade or replace
Life tested and production validated for millions of cycles without failure

Reliable performance with challenging fluids
Capable of dispensing difficult suspensions
Long-term stability for validated processes
Seamless OEM integration
Reduced reagent waste and operating cost

How Does an IVEK Precision Reagent Dispenser Work?

IVEK systems use positive displacement piston technology with no dynamic seals, where fluid volume is controlled mechanically rather than pneumatically, thereby maximizing accuracy and eliminating variability.

Physically displaces a fixed volume of fluid
Accuracy not affected by viscosity or environmental changes
Enables exact dosing independent of fluid properties (viscosity, suspensions, thixotropic nature, density, boiling point)
Provides precise start/stop flow control
Optimized and highly customizable dispense settings
Multi-channel systems available

IVEK dispensers can be operated manually, electronically, or integrated into automated OEM systems using external controllers or software.

How Accurate are IVEK Precision Reagent Dispensers?

IVEK precision reagent dispensers are designed for exceptional accuracy and repeatability, even over extended duty cycles. Accuracies of greater than 0.1% can be achieved. Typical performance characteristics include:

High accuracy across micro-volume ranges (>0.1%)
Outstanding repeatability over millions of dispense cycles
No drift over time
Consistent performance with difficult fluids

Positive displacement operation eliminates air and tubing compression accuracy variations found with time-pressure and peristaltic dispensing systems.

What Fluids Can Be Used With the IVEK Precision Reagent Dispensers?

IVEK precision reagent dispensers are compatible with a wide range of fluids, including:

Aqueous solutions and buffers
Diagnostic reagents
Organic and inorganic solvents
Acids and bases
Suspensions (SPIONs, MNAs, Proteins, AuNPs, DNA/RNA)
Viscous, shear-sensitive, and volatile fluids

Piston/cylinder options include: Al2O3, Y-TZP (HIP), MSZ, SiC, and glass. Pump head construction options, such as 316 stainless steel, Tefzel, and other engineered polymers, ensure chemical compatibility and long service life.
