This high quality, reliable spectrophotometer incorporates advanced features and functions for the ultimate flexibility in operation. Operators can readily create their own custom methods. An included USB stick contains over 260 preprogrammed methods for easy and convenient measurements using Orion AQUAfast, Merck, CHEMetrics or Hach chemistries. You can download any or all of the preprogrammed methods you want.


  • Pre-programmed methods can also be adapted for new chemistries or operators can create their own custom methods and calibration curves
  • Instruments allow a one-point adjustment on any preprogrammed method to correct for variations in batch reagent chemistries
  • Wide variety of vial sizes can be used, including 10mm square vials, 20 and 50mm rectangular vials and an adjustable round vial holder that accommodates 13, 16, and 24mm round vials
  • Three USB connections provide the options to store methods and data to a USB memory stick, transfer data to a computer, and print hard copy data to an external printer
  • System is compatible with ink jet and laser printers with HP PCL 5 or greater


  • Performance verification tests ensure wavelength accuracy and instrument functionality
  • Each verification report gives the time, date and instrument serial number in accordance with GLP and GMP
  • Built-in wavelength accuracy test is compatible with either the internal lamp or external calibrated standards
  • Built-in test methods for stray light, noise and resolution are available to validate instrument performance further

AquaMate 8100 spectrophotometer includes: Test Tube Holder for vials and test tube from 12 to 25 mm OD, 10 mm square single-cell holder, AquaMate Water Analysis Methods Software, Snap-on Printer, Dust Cover, External Power Supply, North America power cable (NEMA 5-15), European power cable (CEE 7/7), UK Power cable (BS 1362).
