 Laboratory

Precision, material purity and reproducibility are crucial in the laboratory environment.
Lézaud offers a customised range especially for laboratory applications Hoses, Round cords, Profiles, Sheets and Stoppers, which are reliably used in analytical, diagnostic and research-related processes.

Chemical resistance, temperature stability and low interaction with media are essential in the laboratory.

Thanks to our comprehensive knowledge of materials and detailed data on the media compatibility of plastics, TPEs and elastomers, we provide targeted advice and deliver solutions that are precisely tailored to your laboratory requirements.
