Pre-owned Microplate Readers

When available BMG LABTECH offers certified pre-owned microplate readers for purchase. Our pre-owned equipment must pass our rigorous quality control standards, just the same as a new reader from our production floor, so you can purchase with confidence that the reader will meet your assay needs. Certified pre-owned BMG LABTECH microplate readers come with a one year parts and labor warranty plus the BMG LABTECH Control and MARS evaluation software.

BMG LABTECH is committed to your satisfaction as a BMG LABTECH customer and we still offer repairs and upgrades for all of our older microplate readers. Original FLUOstars, LUMIstars, Galaxy class, OPTIMA class, and NOVOstars are all fully supported by BMG LABTECH. Our service team stands by our equipment so you can be assured that your pre-owned BMG LABTECH microplate reader will have the same support and service as a new instrument.

PHERAstar Plus

The PHERAstar Plus is an extremely high performance microplate reader for a multitude of assay formats. The PHERAstar Plus features fluorescence, absorbance, luminescence, fluorescence polarization, FRET, BRET, AlphaScreen (some models) and HTRF.  The PHERAstar Plus can still hold its own as one of the most sensitive microplate readers available for these assay formats and is highly regarded in HTS screening labs. The PHERAstar Plus series of microplate readers is optical module based and can use the same optical modules from all PHERAstar derivatives – the original PHERAstar, PHERAstar FS, and PHERAstar FSX. With the PHERAstar Plus incubation to 45C is standard and it is 6 through 1536 well capable. All refurbished PHERAstar Plus readers include the most up to date PHERAstar control and MARS evaluation software plus one-year parts and labor warranty. For more information see the PHERAstar Plus brochure.


Available Features:

  • Fluorescence, Luminescence, Absorbance
  • Fluorescence Polarization
  • FRET
  • BRET
  • Dedicated PMTs and measurement system for HTRF / TR-FRET
  • AS laser for AlphaScreen & AlphaLISA

The CLARIOstar is BMG LABTECH’s most flexible microplate reader and it is the only reader on the market available with the three optical technologies required to run any assay in your laboratory; patented LVF monochromators, UV/vis spectrometer, and high transmission optical filters. The LVF monochromator is the most sensitive monochromator available in a microplate reader with performance that rivals competitor units using filters. The CLAIROstar’s filter measurement mode provides the best performance available in a microplate reader for FP, HTRF, and AlphaScreen. The CLARIOstar features 45C or 65C incubation, AlphaScreen laser, two reagent injectors, and there is an available atmospheric control unit (ACU) that will open up a great many possibilities for live cell based assays. Refurbished CLARIOstars include the newest software and come with a one-year parts and labor warranty. Please see the CLARIOstar Brochure for additional details.

FLUOstar Optima

The OPTIMA series is a family of filter-based single and multi-mode readers that are a solid staple of life science laboratories. The OPTIMA can perform all life science measurement modes in top or bottom reading configuration: fluorescence, absorbance, and luminescence with a high degree of sensitivity. Optional on-board reagent injectors allow the OPTIMA to perform any real-time injection based applications just like the BMG LABTECH CLARIOstar and OMEGA series of microplate readers. Incubation to 45C is standard and the OPTIMA can read 6 well through 384 well plates. A refurbished OPTIMA come with software and a one-year parts and labor warranty. More information is available in the OPTIMA brochure.


Available Features:

  • Fluorescence, Luminescence, Absorbance
  • Accommodates up to sixteen filters
  • Two reagent injectors
  • 45C incubation

The original NEPHELOstar is BMG LABTECH’s first generation laser-based plate reader nephelometer and can be used for solubility studies, turbidity measurements, cell growth, bacterial growth, and much more. The NEPHELOstar can read 6 to 384 well plates in and with adjustable laser focus and intensity the analytical area of interest inside the well can varied as needed for an experiment. The NEPHELOstar can be equipped with two optional regent injectors that can be used to deliver between 5 to 350uL per well, and, each well can receive differing amounts of reagent allowing dilution series and gradient injections to be performed. Incubation to 38C is standard on the NEPHELOstar so that the measurements always take place in controlled conditions. The NEPHELOstar comes with instrument control software and data is conveniently provided in ASCII output which can be imported and analyzed with third party software. Comes with one-year parts and labor warranty.

FLUOstar Omega

The OMEGA series of microplate readers replaced the OPTIMA as BMG LABTECH’s entry-level life science microplate reader. The OMEGA features fluorescence, luminescence, and spectrometer-based UV/vis absorbance that is a unique and industry leading technology. The spectrometer provides the entire absorbance spectrum, from 220nm to 1000nm, in under one second per well. Coupled with the BMG LABTECH LVis plate you can rapidly and accurately quantitate microliter sized samples. Fluorescence and luminescence measurements are filter based and extremely sensitive allowing high-performance assays like FRET and BRET/NanoBRET to be utilized. The OMEGA series has a large number of options making it possible to run any life science assay: dual on-board injectors, 65C incubation, atmospheric control unit, and much more. Refurbished OMEGAs have a one-year parts and labor warranty and include all the software needed to run assays and analyze data.

Available Features:

  • Filter and spectrometer technology
  • Fluorescence, Luminescence, Absorbance modes
  • FRET & BRET capable
  • FP, HTRF, and AlphaScreen options
  • Two reagent injectors
  • 6 to 384 well capable
