Very good device
Cell counting
Luna II is a user-friendly and intuitive device for cell visualization and counting that has greatly enhanced our team’s workflow. I would strongly recommend it.

Great time-saver, great cost-saver in the long run.
Pharmaceutical Sciences
The Luna FX7 is an incredible asset for any lab that works on human cells. Compared to manually counting cells on a hemocytometer which can take almost half an hour per sample, this equipment, like other automated cell counters, can do that in less than a few seconds and do all the required cell concentration calculations at the same time. But where this wins over other automated cell counters are recurring costs and convenience. Even though the initial unit is quite pricey, the fact that this can accommodate 8 sample slides kills two birds with one stone: - It greatly pushes down the cost of each sample counted to just a few cents. - It allows automated counting of multiple related samples all at one go. Overall, this automated cell counter is a very worthwhile investment to enhance the speed and value of any lab that works on human cells.

Easy and useful
Cancer research
I have used LUNA-III everyday since February, analysing thousands of samples. I have noticed the great accuracy of this cell counter, which is better than others we have tried in the past. The dimensional range set in the protocol is easily adaptable to different cell types and the instrument follows them accurately. With the instrument, the company provided us disposable slides, which are very useful and convenient. Even working with the reusable slide is easy. With LUNA-III we have been able to count samples in a short time, it would have never been possible without it.

This is a very easy and affordable cell counter. We have challenged and stressed it with heterogeneous glioma cells, from relatively low density to high amount of cells (in the order or thousands) having reasonable conts and also being reproducible.

How to validate automated cell counters: Benefits of using validation slides over NIST standard beads
In this application note, Logos Biosystems explains the benefits of using validation slides over NIST standard beads. Automated cell counters have become popular for their ability to offer rapid and precise cell counting results. While beads are commonly used for validation in devices like flow cytometers and automated cell counters, they present various challenges. To address these issues, Cell Counter Validation Slides have been developed for validating the LUNA™ cell counter series. These slides offer stability and consistency, eliminating problems such as concentration manipulation and uneven distribution. Additionally, they allow for verification of total cell count and viability using both brightfield and fluorescence optics. By incorporating validation slides, researchers can save time and resources typically spent on additional experiments to ensure accuracy.
Maximize research capacity with cell counting efficiency
Automation addresses many of the cell counting challenges faced by the modern lab and the latest image-based automated cell counters are essential in delivering cell concentration and viability data with greater accuracy, reliability, and higher throughput than ever before.
Through case studies, this eBook highlights a range of automated cell counters from Logos Biosystems that are designed to address all your cell counting needs.
