Product description

Microplate reader with grating monochromator, 8-channel optics, and temperature control for absorbance assays (340–850 nm).

The Molecular Devices VersaMax™ Absorbance Microplate Reader is a versatile instrument designed for precise and accurate absorbance measurements across the visible spectrum (340–850 nm) without the need for filters. This flexibility makes it ideal for a wide range of applications in biotechnology, molecular biology, and clinical diagnostics.

Key features include:

  • Grating monochromator: Allows selection of up to two wavelengths simultaneously, enhancing assay flexibility.
  • Multichannel optical design: Mimics a dual-beam spectrophotometer, measuring each sample directly to eliminate errors from light output variations.
  • Eight-channel system: Delivers high precision and speed when reading 96-well microplates for endpoint measurements and kinetic assays.
  • Temperature control: Maintains consistent temperatures up to 45°C, essential for temperature-sensitive assays.
  • SoftMax® Pro Software: Industry-leading data acquisition and analysis software included for comprehensive data handling.

This microplate reader is widely used in university laboratories, biomedical research centres, and biopharmaceutical companies for applications such as:

  • Enzyme-linked immunosorbent assays (ELISAs)
  • Enzyme kinetics studies
  • Cell proliferation and cytotoxicity assays
  • Microbial growth monitoring
  • Protein quantification

First introduced in the late 1990s, the VersaMax™ remains relevant due to its robust performance and adaptability, continuing to support critical research and development in the biotechnology sector.

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.
