Fluidnatek® LE-50 Prosterile

Product Overview

The Only Electrospinning System Equipped for Sterile Development of Medical Products

Ideal for biomedical companies requiring aseptic sample development for medical products under ISO-5 environment, cGMP, and ISO-13485 certification standards. The Fluidnatek LE-50 ProSterile is the instrument of choice for in-line aseptic electrospun bioprocesses, and medical device manufacturing of sterile products. This system has elevated the electrospinning technique into a new era of ultra-clean medical device processing. 

Maintain Sterility

Multiple methods of sterilization ensure that your sample remains sterile from beginning to end

ISO-5 / Class 100 Cleanliness

Ultra-clean medical device processing for personalized medicine. Maintain ISO-5 cleanliness with a vacuum transfer vessel

Optimize Reproducibility

Environmental Control supports increasing/decreasing temperature, relative humidity

cGMP Certifiable

Validation for cGMP processes through IQ/OQ/PQ documentation packages

LE-50 ProSterile Features

The LE-50 ProSterile is the first electrospinning system to offer a fully sterile process environment, enabled by its welded stainless steel interior and exterior, HEPA filtration to meet ISO-5/Class 100 cleanliness standards, and a chamber sterilization system. Glove port access allows sample handling and packaging under sterile conditions, and the vacuum antechamber removes possible traces of solvents while maintaining an exceptional standard of sterility and cleanliness. An environmental control unit (ECU) enables precision control of temperature (18-45°C), and relative humidity (10-80%) to maintain batch-to-batch reproducibility for perfect nanofibers, every time.
