As is well-known in brewing and winemaking industries, the quantity of yeast pitched to initiate fermentation directly affects the flavor, aroma, and quality of the final product. Although yeast can be pitched by weight or volume, such methods are inexact and highly variable. The ASBC method using methylene blue method is more accurate but time consuming and subjective. Use the LUNA-II YF™ to get accurate and reproducible yeast cell counts in as little as 15 seconds. This little counter sits comfortably in a cell culture hood or on your benchtop to fit seamlessly into your workflow.

WHAT THE LUNA-II YF™ DOES BEST

  • LUNA-II YF™ Automated Yeast Cell Counter Accurate yeast cell counts
    ACCURATE YEAST CELL COUNTS

    The LUNA-II YF™ provides cell count and viability data with the precision
    and consistency of a flow cytometer.

  • LUNA-II YF™ Automated Yeast Cell Counter 15 seconds to results
    15 SECONDS TO RESULTS

    Using dual fluorescence optics, an autofocusing liquid lens, and advance
    software, the LUNA-II YF™ produces data in just 15 seconds.

  • LUNA-II YF™ Automated Yeast Cell Counter Yeast-optimized analysis
    YEAST-OPTIMIZED ANALYSIS

    Unlike flow cytometers, the LUNA-II YF™ has advanced declustering
    capabilities, and can count even the clumpiest cells.

  • VERIFIED WITH MULTIPLE STRAINS

    We’ve independently tested 30+ brewing yeast products on the LUNA-II YF™.

Testimonials
  • Le Dinh De

    Sabeco (Saigon Beer-Alcohol-Beverage Corporation)

    Great product. I am an equipment manager. I am very pleased with this product to check and count enamel in beer. Fast, accurate and complete parameters are the most basic factors. It is very easy to use. After sales care service is very good. Product worth the money.

  • Jesse Hudgins
