The BIOFLOAT™ 96-well plate & BIOFLOAT™ 384-well plate have nanometer-thin uniform coating that supports spheroid formation even with cells that do not aggregate easily.

  • BIOFLOAT™ plates enable rapid formation of spheroids from human primary hepatocytes.
  • Spheroids exhibit unique characteristics: uniformity, vitality, and reproducibility.
  • Key cellular properties are excellently reproducible with BIOFLOAT™ plates.

Following data have been recently published in the Biotechnology Journal as results of the study The choice of ultra-low attachment plates impacts primary human and primary canine hepatocyte spheroid formation, phenotypes and function conducted at the Karolinska Insitutet by the group of Prof. Dr. Volker M. Lausche. 

BIOFLOAT plates allow for the rapid and reproducible formation of spheroids from human primary hepatocytes. Formed spheroids have unique properties in terms of uniformity, viability and excellent reproducibility of key cellular properties. Spheroids formed in BIOFLOAT are particularly well suited for High-throughput pharmacological and toxicological experiments.

The variability between different measurements of analytical parameters like metabolic enzyme activitiy is lower in spheroids formed in BIOFLOAT plates compared to spheroids formed in other ultra-low attachment plates.

Long-term cultivation of viable spheroids in BIOFLOAT™  plates

According to the results of the benchmark study, BIOFLOAT™  plates enable long-term cultivation of highly viable primary human
hepatocyte spheroids. ATP levels as an indicator of cell viability are preserved for an extended period of time.

Highly reproducible spheroid formation in BIOFLOAT™ plates

The authors observed 100% single spheroid formation of primary human hepatocytes only in BIOFLOAT™ plates among the tested 384-well plates.

-> BIOFLOAT™ plates are particularly well suited for high-throughput pharmacological and toxicological experiments.

Rapid spheroid formation in BIOFLOAT plates

The figures show considerably faster primary human hepatocyte spheroid formation in BIOFLOAT plates (3 days) compared to competitor plates (5 to 6 days). 

BIOFLOAT plates are best suited for high-throughput pharmacological and toxicological experiments.

Metabolic active spheroids in


In the benchmark study, primary human hepatocytes formed spheroids with high metabolic enzyme activity in BIOFLOAT™ plates.

BIOFLOAT plates showed the lower variability between different measurements of the same metabolite compared to competitor plates -> High data consistency and reproducibility.

Rapid spheroid formation

Shorten your experiment timelines. Single spheroids form faster on BIOFLOATTM surfaces than on most other ultra-low attachment surfaces.

Round and Uniform

The 3D cell culture and maintenance on the BIOFLOAT™ surfaces result in highly uniform spheroids and perfect data consistency. Cell satellites and irregular aggregations are eliminated.

Reliable spheroid culture

The reliable quality of the BIOFLOAT™ surface makes it a premium product for spheroid and organoid culture, including cells which fail to generate spheroids on existing products.

The reliable quality of the BIOFLOAT™ cell culture surface enables the formation of perfect spheroids even for challenging cells. This also includes cells that do not form spheroids on existing products.

Raw Material Processing

The product does not use any rawmaterials of animal
or biological origin and therefore does not have TSE/BSE.

The polymer raw materials used for coating plates were positively evaluated
for quality consistency using GPC, GC-MS and NMR spectroscopy.

The sterile, non-pyrogenic/endotoxin-free, non-cytotoxic, DNase-/RNase-/DNA-free multi-well plates were coated using pipetting robots.
Coated plates were sterilized by electron beam irradiation
