Frequently asked questions
Find answers to the most common questions about our equipment, manufacturing processes, standards, and services.
What is a fume hood and what is it used for?
A fume hood is a containment device designed to protect the operator from vapors, gases, and particles generated during laboratory procedures. It works by creating airflow that captures hazardous substances and exhausts them through a filtration system or ductwork to the outside.
What is the difference between a biosafety cabinet and a laminar flow cabinet?
A biosafety cabinet protects the operator, the product, and the environment from hazardous biological agents using HEPA filters and directional airflow. A laminar flow cabinet only protects the product or sample using unidirectional HEPA-filtered airflow, without protecting the operator from what is handled inside.
