AI Technical Summary

Technical Problem

Existing laboratory incubators face challenges in maintaining homogeneous temperature distribution and preventing condensation, especially at chamber openings and edges, which can lead to contamination and inefficiencies in cell culture experiments.

Method used

The laboratory device employs a heating system with varying heat flux density by using heating coils with different surface densities and materials to compensate for heat losses in critical areas, ensuring uniform temperature distribution and preventing condensation.

Benefits of technology

This approach achieves a stable and homogeneous temperature distribution within the chamber, reducing the risk of condensation and contamination, thereby optimizing incubation conditions for biological samples.
