IncludesStandard care

Vertical laminar flow cabinet providing ISO Class 5 sterile conditions through HEPA-filtered downward airflow for aseptic laboratory operations and cell culture work.

A laminar flow clean bench protects only the sample. It blows filtered air toward the user, so it is not for infectious or toxic work.

The Vertical Laminar Flow Cabinet provides ISO Class 5 (Class 100) sterile working conditions through HEPA-filtered vertical airflow for aseptic laboratory operations. The unit delivers consistent downward airflow at 0.30-0.45 m/s velocity through a single HEPA filter with 99.995% efficiency at 0.3 micrometers, creating a contamination-controlled workspace measuring 1200×645×625mm internal dimensions.

Key operational features include motorized front window control, LCD display for system monitoring, and colony contamination levels maintained at ≤0.5 CFU/30 minutes. The cabinet operates with minimal vibration (≤5 micrometers rms) and noise levels (≤65 dB(A)) while providing ≥300 lux illumination for detailed work visibility. Pre-filtration through polyester fiber extends HEPA filter life and maintains consistent performance in cell culture, microbiology, and pharmaceutical preparation applications.

How It Works

Vertical laminar flow cabinets operate on the principle of unidirectional airflow to create a sterile workspace. Room air is drawn through a polyester fiber pre-filter to remove larger particulates, then passes through a HEPA filter positioned at the top of the cabinet. The HEPA filter removes 99.995% of particles 0.3 micrometers and larger through mechanical filtration mechanisms including impaction, interception, and diffusion.

Filtered air flows vertically downward at controlled velocity (0.30-0.45 m/s) creating a laminar flow pattern that sweeps contaminants away from the work surface. The motorized front window maintains proper airflow dynamics while allowing operator access. The downward airflow pattern continuously removes particles generated within the workspace, maintaining ISO Class 5 conditions with colony counts ≤0.5 CFU per 30 minutes.

The LCD display monitors critical parameters including airflow velocity, filter status, and operational hours to ensure consistent performance. Low vibration operation (≤5 micrometers rms) prevents disturbance of sensitive cell culture work, while adequate illumination (≥300 lux) provides clear visibility for detailed manipulations.

Feature	This Product	Typical Alternative	Advantage
HEPA Filter Efficiency	99.995% efficiency at 0.3μm	Basic models often provide 99.97% minimum efficiency	Higher efficiency removes smaller particles for enhanced sterile conditions in critical applications.
Front Window Control	Motorized window positioning	Manual sash positioning is common in entry-level units	Maintains consistent airflow dynamics without requiring manual adjustment during operation.
Airflow Monitoring	LCD display with system monitoring	Basic models may have simple indicator lights	Real-time parameter monitoring enables proactive maintenance and performance verification.
Contamination Control	≤0.5 CFU/30 minutes specification	Standard models may not specify colony count limits	Quantified contamination levels provide measurable sterility assurance for critical work.
Vibration Control	≤5μm rms vibration specification	Entry-level units may lack vibration specifications	Low vibration operation essential for microscopy work and sensitive cell culture manipulations.
Pre-filtration System	Polyester fiber pre-filter included	Some basic models lack pre-filtration	Extends HEPA filter life and maintains consistent performance by removing larger particles first.

This cabinet combines high-efficiency HEPA filtration (99.995% at 0.3μm) with motorized window control and comprehensive monitoring through LCD display. The specified contamination levels (≤0.5 CFU/30 minutes) and low vibration operation (≤5μm rms) support demanding sterile applications requiring quantified performance verification.
