Microlab 600 in Forensics

Hamilton Forensics

Without the Microlab 600

  • Blood alcohol samples and calibrators are diluted with pipettes
  • Volatile solutions tend to drip from 
air displacement pipettes
  • Calibration of pipettes can drift 
during use, opens results to 
scrutiny from attorneys
  • User to user variability reported at 3%

After Implementation of the Microlab 600

  • The positive displacement design eliminates dripping of volatiles
  • Stepper motor with optical 
encoder that calibration 
cannot be questioned
  • User-to-user variation was 
reduced to less than 1%
  • Log files provide relevant documentation for 
regulatory concerns


Forensics Applications

In the forensic industry, results are under constant scrutiny for accuracy. A traceable chain of custody from sample collection clear through data analysis is required so there can be no doubt of the results. The Microlab 600 is a critical link in the sample preparation portion of this chain. Learn more about forensic science automation.

Common Applications

Blood Alcohol Analysis and Urinalysis both require that the sample is diluted, spiked with internal standard and loaded into a headspace vial for processing. The Microlab 600 completes this task with only two presses of the hand probe trigger. One to aspirate the sample and one to complete the dilution in the headspace vial. The sample is washed from the tubing by the diluent so the Microlab 600 is immediately ready to process the next sample.

Why Choose the Microlab 600?

The Microlab 600 comes with a calibration certificate that is traceable to N.I.S.T. standards. The Microlab 600 is a positive displacement system that is not susceptible to variations in atmospheric pressure like traditional air displacement pipettes. Dilution methods are stored on the system and recalled prior to use, ensuring that the same method is followed day in and day out. The user simply triggers the hand probe to aspirate or dispense the liquid. By automating the pipetting functionality, the technique-dependent variability is minimized.
