Product description

Absorbance microplate reader with 400-750 nm range, dual-wavelength, and kinetic assay capability, essential for molecular diagnostics.

The BioTek ELx800 Microplate Reader is a versatile absorbance microplate spectrophotometer optimized for clinical diagnostics and life science research, including biotechnology applications such as molecular diagnostics and bioprocessing workflows. Designed to support ELISA assays, enzyme activity measurements, kinetic studies, and well area scanning with single- or dual-wavelength reading, it offers precise optical performance across a wavelength range of 400 to 750 nm.

Key technical features include:

  • Wavelength range: 400–750 nm, suitable for a broad spectrum of absorbance assays
  • Dynamic range: 0 to 3.0 OD with high linearity (<1% at 3.0 OD) and accuracy (<1% at 2.0 OD)
  • Repeatability: <0.5% at 2.0 OD, with resolution of 0.001 OD for reliable quantitative data
  • Plate compatibility: Supports 24-, 48-, and 96-well microplates, accommodating standard laboratory formats
  • Light source: Tungsten halogen lamp for stable illumination with five-filter capacity
  • Onboard software: Stores up to 55 assay protocols and 25 standard curves; features multiple curve fitting options (linear, cubic, 4-parameter logistic, log-logit, spline) alongside assay validation tools and data transformation capabilities
  • Data handling: Stores up to 8 microplate results simultaneously, enabling efficient data management
  • Integration: Compatible with BioTek Gen5 software for enhanced PC control and data analysis, suitable for synthetic biology labs and biomanufacturing process monitoring

Its compact footprint (15 x 17 x 16 inches) and 20 lbs weight support benchtop use in diverse laboratory environments. This microplate reader is widely utilized in molecular biology, biotechnology research, clinical diagnostics, and bioprocessing pipelines—making it essential for gene editing assays, protein quantification, and live-cell analysis setups.

The BioTek ELx800 is a reliable instrument known for delivering high-precision absorbance measurements critical in complex biomanufacturing workflows and synthetic biology research, where assay reproducibility and kinetic monitoring are paramount.

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.
