The first device that combines Cell Counting and Spectrometry

Combining a full-fledged spectrometer with an automated cell counter, a variety of analyses such as absorbance, scatterlight and time-series measurements, automated cell counting and staining-free viability measurements can be performed. The intuitive handling and precise measurements make the fluidlab R-300 the laboratory instrument of the future.

Key Features

  • Automated Cell Count
  • Staining Free Viability Measurements
  • Extinction & Kinetics (375-700 nm)
  • Maintenance free

Acella sample carrier

The acella, a proprietary sample carrier format that uses a glass substrate, is the optimal multi-purpose slide for your cell counting and viability assessment. It comes in three different chamber heights (20µm, 50µm, and 100µm) to ensure the best possible results from measurements of very small and large cells or heterogeneous cell samples.

Fluidlab R 300 - Application Examples and Functions

  • Biopharmaceutical and Biotechnology
Anvajoanvajo GmbH is a Dresden-based technology company that develops, manufactures and sells innovative solutions for the analysis of liquids. Our interdisciplinary team is working enthusiastically on the world's most compact universal platform for fluid analysis, the "fluidlab". It combines the instrument itself, a software suite and multifunctional sample carriers. The system of the "fluidlab" is based on progressive technologies such as holographic microscopy, machine-learning-supported image analysis, mobile embedded hardware, function-integrated optics and meso- and microfluidic sample carriers. Since August 2019, production and sales of the first series product based entirely on the "fluidlab" - a point-of-care testing solution on behalf of a leading veterinary company - have been underway.
