LUNA-II YF™ Automated Yeast Cell Counter

Yeast strains used in food and drink production can be notoriously clumpy. 
The LUNA-II YF™ has an autofocusing cell counting and declustering algorithm that counts individual yeast cells in just 15 seconds.

Technology

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

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.

Yeast-Optimized Analysis

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