Thermostatic test chamber

temperaturestabilityenvironmental

Overview
The temperature-controlled chamber provides precise regulation of environmental conditions in the deposition area to improve control and reproducibility of nanofibers and nanoparticles during electrospinning/electrospraying processes. It enables fine tuning of process parameters to meet target specifications and to ensure stable, repeatable deposition.

Main advantages

• Increases process uptime and reduces production interruptions caused by nozzle clogging or solvent-related instabilities.
• Improves sample uniformity and reproducibility of fiber and particle morphology.
• Facilitates process scaling for higher throughput under controlled conditions.

Importance of temperature control
Phase separation: Temperature management limits unwanted phase separation in polymer blends during deposition, improving compositional uniformity and surface quality.
Solvent evaporation rate: Temperature directly affects solvent evaporation from deposited jets, influencing Taylor cone stability and final morphology; controlled evaporation prevents incomplete or discontinuous deposition.
Process stability: Reducing temperature fluctuations maintains continuous operation and lowers defect rates and variability between batches.
Nanofibers / nanoparticles morphology: Optimised temperature settings allow control of fiber diameter and particle size, enabling target morphological properties for specific applications.

Literature and rationale
Controlling chamber temperature is a key parameter reported in literature to affect solvent evaporation, jet stability and homogeneous structure of deposited material. A controlled chamber design improves charge dissipation and minimizes defects such as beading, fiber bundling or agglomeration, yielding reproducible nanostructures suitable for downstream applications.
