Logos Biosystems : What instruments for cell counting, imaging and sample preparation?

Logos Biosystems designs instruments for automated cell counting, imaging and sample preparation for life science laboratories. With its LUNA (cell culture and QC), QUANTOM Tx (microbiology) and X-CLARITY (3D tissue clearing) ranges, the brand streamlines critical steps, from viability assessment to high-content imaging. It stands out with intuitive workflows and fast, reproducible results, supporting R&D, quality control and bioproduction.

A cutting-edge leader, now the go-to partner.

Founded in 2008 and headquartered in South Korea, Logos Biosystems was born from a simple idea: make cell counting faster, more reliable and more accessible than the traditional haemocytometer. The first generation of LUNA automated counters quickly gained traction in cell culture labs. The brand then broadened its scope: LUNA-FL for fluorescence, dedicated yeast versions, and high-throughput instruments. In parallel, it expanded into imaging with CELENA X and into 3D sample preparation with X-CLARITY, an automated tissue-clearing system. Backed by renowned application support and agile R&D, Logos Biosystems is today a trusted partner for R&D, QC and production teams across Europe and worldwide.

Expertise and areas of specialisation

Logos Biosystems excels in three key areas, all designed for precise, fast and reproducible results. 1) Eukaryotic cell counting and viability. The LUNA-II (trypan blue staining) and LUNA-FL (fluorescence, e.g. AO/PI) counters automate focusing, acquisition and analysis with robust algorithms and thoughtful ergonomics. Specialised versions for yeast deliver reliable monitoring of fermentation cultures. The LUNA-FX7 pushes throughput further with multi-channel slides, a wide analysis area, autofocus and built-in quality controls — standardising day-to-day counting and reducing inter-operator variability. 2) Microbial counting. The QUANTOM Tx Microbial Cell Counter leverages fluorescence and imaging to enumerate individual bacteria, including within clusters, where conventional methods struggle. Result: fast, consistent data for microbiology R&D and process control. 3) Imaging and sample preparation. CELENA X streamlines automated imaging on slides and plates, for experiment tracking and routine quantification of cellular objects. For thick specimens, X-CLARITY automates polymerisation & clearing for 3D visualisation (soft tissues, organoids), bringing standardisation and time savings. In practice, the brand stands out with clear interfaces, dedicated slides (reusable and disposable) and data-export options aligned with laboratory requirements. It also helps reduce the plastic footprint through optimised consumables and the durability of optical components. Altogether, it offers a coherent solution for cell culture, microbiology, neuroscience and QC across academic, industrial and biopharmaceutical settings.

Frequently asked questions about the Logos Biosystems brand

What’s the difference between LUNA-II and LUNA-FL?
LUNA-II measures viability with trypan blue. LUNA-FL adds fluorescence (e.g., AO/PI) for challenging or low-contrast samples.

Is the LUNA-FX7 suitable for high-throughput?
Yes. It offers multi-channel slides, a large analysis area and built-in quality controls to standardise routine counting.

Can you count yeast and bacteria?
Yes. LUNA versions exist for yeast, and the QUANTOM Tx is dedicated to bacterial counting via fluorescent imaging.

Are slides universal across models?
No. Each instrument uses dedicated slides (reusable or disposable). Check the reference compatible with your model.

What is X-CLARITY for?
To automate tissue clearing for 3D imaging of soft samples (e.g., brain tissue, organoids) with reproducible results.

What about environmental impact commitments?
The brand prioritises the reduction of consumables (reusable slides) and system durability, while supporting correct use to limit waste.
