Application Areas


Example Topics

Clinical Pathology
  • Researching sepsis causes, progression and processes
Sports Science
  • Using blood lactate levels as a marker for training intensity in a wide variety of sports
  • Studying the effects of exercise on the body
  • Studying the effectiveness of post exercise recovery aids
  • Analysing the effects of conditions and environment on physical performance
Agricultural & Veterinary
  • As a marker of the presence and severity of tissue hypoperfusion
  • In diagnosing cavitary effusions
Biotechnology & Pharmaceutical Analyses
  • Process control in biotechnology (production of lactic acid)
  • Developing drugs for sepsis
Food & Beverage Analyses
  • As a marker for spoilage in eggs, milk, tinned fruits and vegetables
  • Monitoring malolactic fermentation in wine (Oenology)
  • Improving the flavour and stability of foods


After calibration with a standard of the selected metabolite, the single injection of sample is all that is needed to obtain a result and prepare the analyser for the next analysis.

Sample injection via an accurate positive displacement pipette triggers the complete analytical cycle and a hard-copy result is printed within 25 seconds.

"I have used the LM5 Lactate Analyser in past research of whole blood, plasma, or serum lactate levels during changing metabolic demand, such as during exercise or hypoxic exposures. I always found this analyser to be cost effective, time efficient, and irreplaceable in circumstances where immediate blood lactate results are needed to ascertain cellular or systemic responses to altered muscle metabolic demand. This is especially important in field research where and when you do not have the resources or capacity to adequately process and store human samples for latter analyses. This instrument should be in every exercise, sports and basic science physiologist’s laboratory arsenal of equipment."
