The Molecular Devices SpectraMax L 1-Channel Luminescence Microplate Reader is a high-sensitivity laboratory luminometer designed for measuring luminescence from microplate-based biological and biochemical assays. The instrument shown in the image is clearly labeled SpectraMax L and 1-Channel, identifying it as the single-channel configuration of the SpectraMax L platform.

The SpectraMax L uses a low-noise photomultiplier tube (PMT) with simultaneous photon-counting and analog detection modes. Molecular Devices specifies a spectral range of 380–630 nm, sensitivity of less than 20 attomol ATP per well, and a dynamic range exceeding 9 orders of magnitude.

The platform is designed for both 96-well and 384-well microplates and supports endpoint, kinetic, fast-kinetic and dual-read measurements. Depending on configuration, the SpectraMax L can also include programmable reagent injectors, temperature control, barcode reading and automated plate handling. The photographed unit shows substantial cosmetic wear and staining consistent with previous laboratory use.

Applications

The SpectraMax L is suitable for luminescence-based biochemical and cell-based assays, including ATP-based cell viability assays, reporter gene assays, luciferase assays, chemiluminescent ELISA, cellular signaling and protein detection. Molecular Devices also lists applications in drug discovery, cytotoxicity testing, microbiology and BRET/NanoBRET workflows.

The 1-channel configuration can be used for sequential measurement of luminescent signals from microplate wells. Published research has also used SpectraMax L 1-channel luminescence plate readers for long-term bioluminescence measurements in cell-based experiments.

Technical Specifications

Molecular Devices documentation specifies dimensions of approximately 42 cm W × 43 cm D × 22 cm H and a weight of approximately 16.4 kg. The documented instrument accepts standard SBS-format 96- and 384-well microplates.

The SpectraMax L platform can also be configured with variable-volume injectors. The manufacturer's documentation describes optional injector configurations, with documented delivery volumes beginning at approximately 10 µL and extending to 100 µL depending on configuration.

Benefits of Refurbished Laboratory Equipment

A refurbished SpectraMax L 1-Channel can provide laboratories with access to established high-sensitivity luminescence detection technology for research and assay-development applications. Its PMT-based detection system and wide dynamic range make it suitable for measuring both relatively weak and strong luminescent signals without requiring the same degree of sample dilution.

Refurbished microplate readers can be a practical option for academic laboratories, biotechnology facilities, pharmaceutical research groups and assay-development laboratories using established luminescence workflows. Before routine use, the reader should be professionally inspected and tested for PMT performance, plate positioning, optical system operation, software communication and measurement accuracy.

Additional Information

The photographed unit is a used/refurbished Molecular Devices SpectraMax L 1-Channel Luminescence Microplate Reader and shows visible cosmetic wear, dirt, discoloration and surface damage. The image does not confirm the presence of optional injectors, temperature-control hardware, barcode reader, validation plate or automation accessories.

The SpectraMax L is designed to operate with SoftMax Pro software, and optional automation/stacking capabilities are available for compatible configurations. The exact software version, computer/interface hardware and included accessories should therefore be verified before purchase.
