Clean Benches

Clean Benches provide a particle-free working environment by directing HEPA-filtered airflow across the work surface to protect samples from contamination. Commonly used in microbiology, electronics assembly, life sciences, and medical laboratories, clean benches offer reliable laminar flow performance for applications that demand sterile, dust-free conditions.


We offer a diverse range of clean bench models to meet specific workspace, process, and safety requirements:

  • Vertical Laminar Flow Clean Benches: Deliver filtered air vertically from top to bottom, offering high contamination control for sensitive experiments. Ideal for microbiology, tissue culture, and sample preparation.

  • Horizontal Laminar Flow Clean Benches: Provide laminar airflow across the work surface from back to front, ensuring operator comfort and uniform air distribution. Widely used in electronics, precision instruments, and sterile packaging.

  • Portable Clean Benches / Tabletop Models: Compact and lightweight units designed for flexible use in space-constrained environments, field laboratories, or mobile research setups.

  • PCR Cabinets / PCR Workstations: Specialized clean benches with built-in UV sterilization and vertical laminar flow for contamination-free PCR setup. Essential for molecular biology, nucleic acid amplification, and clinical diagnostics.

  • Customizable Clean Benches: Tailor-made solutions with adjustable sizes, airflow configurations, UV lighting, and additional features to suit unique laboratory workflows and spatial constraints.


All our clean benches are equipped with high-efficiency HEPA filters, quiet operation systems, and ergonomic designs to enhance safety, productivity, and sample protection. With advanced airflow control and optional UV sterilization, they help maintain ISO Class 5 (or better) clean air environments to meet your strict laboratory standards.
