Culture Plate Insert

For Tumor Spheroids

  • High throughput culture. Create up to 40 uniform spheroids from a single pipetting step.

  • Disturbance free solution exchanges that eliminates the possibly of aspirating spheroids.

  • Monosize spheroids for experimental consistency.

  • Directly embeddable in paraffin for in-situ IHC and H&E analysis - eliminates the need for manual manipulation. 


The EZ-Seed is a culture plate insert for creating a uniform, monosize tumor spheroids. Our unique design enables the creation of up to 45 spheroids from a single pipette cell seeding. The insert is perfectly suited to various types of assays and standard laboratory imaging equipment, making it suitable to a wide range of experiments. The open-well design also enables seamless transfer of spheroids to well plates for drug testing or additional test conditions.
