Luna- II Automated Cell Counter

The Logos Biosystems Luna II is a compact automated cell counter with reusable slide option

Features & Benefits

Affordable Running Costs
Low cost disposable slides or use the optional Luna reusable slide to further reduce ongoing costs as well as save on plastic waste

Accurate and Reliable Data
Large counting volume of 0.5 microlitres (equivalent to 5 large haemocytometer squares) provides count and viability data you can rely upon

Extensive Cell Information
Histogram with cell size gating and cluster map, provide a clearer picture of your cell population

Advanced Declustering
Sophisticated declustering algorithms provide accurate counts for even clumpy cell types

Easy To Use
Intuitive colour touchscreen interface with no need for special training

Flexible Data Handling
Export count, image or report data for offline viewing or sharing
