Reliable, accurate, reproducible microvolume measurement by Drop Technology, Ireland. Our instruments are different because they are based upon the science of behaviour of tiny drops of liquid (something which may surprise you). The drop under test is nature's cuvette and we have patented this principle in our product.


TLDA µV Spectrophotometer

  • Transmitted Light Drop Analyser for Micro volume sample Analysis
  • New benchmark in accurate and precise Nucleic Acid, Protein and UV/VIS Micro volume measurement
  • Instrument Control by in-built 8.25" Colour Touch-screen LCD
  • Patented "True Drop Science" Spectral Quantitation Technique
  • Patented Optical Design maintains constant pathlength of the drop-under-test (DUT)
  • Only one surface to wipe. A single Quartz Plinth on which the sample sits
  • No manipulation or squashing of the sample
  • No Fibre Optics in contact with the sample
  • Easy to use rapid sample placement, measurement and removal
  • No Carry-over from Sample to Sample
  • Only Microvolume Spectrophotometer which can be calibrated using NIST Traceable Standard
