Erlab XLS483F Vertical Laminar Flow Clean Bench

Overview

The Erlab XLS483F Vertical Laminar Flow Clean Bench is an ISO Class 5-certified containment workstation engineered for precision-critical applications requiring particle-free ambient conditions. It operates on the principle of unidirectional vertical laminar airflow: air is drawn through a pre-filter, conditioned by a high-efficiency centrifugal fan system, and then passed through an H14-grade HEPA filter (tested per EN 1822-1 at Most Penetrating Particle Size, 0.3 µm) before being delivered downward across the work surface at a uniform velocity exceeding 0.3 m/s. This airflow architecture ensures continuous displacement of airborne particulates away from the operator and sample zone—minimizing cross-contamination and maintaining consistent sterility. Designed and manufactured in France, the XLS483F complies with EN ISO 14644-1 for cleanroom classification and meets both U.S. Federal Standard 209E Class 100 and EU GMP Annex 1 requirements for Grade A and B environments. Its structural integrity, airflow stability, and filtration longevity are validated under routine laboratory operating conditions, supporting long-term reproducibility in regulated and research settings.

Key Features

• Triple LP44 centrifugal fan system delivering stable, low-turbulence airflow at 690 m³/h with <58 dB(A) acoustic output—optimized for operator comfort during extended use.
• H14 HEPA filter certified to ≥99.995% efficiency at 0.3 µm (EN 1822-1 MPPS method), with service life up to 4 years depending on ambient particulate load and maintenance of upstream pre-filters.
• Integrated differential pressure monitoring system enables real-time tracking of pressure drop across both pre-filter and HEPA filter—providing objective, quantitative criteria for scheduled replacement.
• Dual-stage alarm system: audible and visual alerts activate immediately upon fan failure or critical airflow deviation, ensuring procedural continuity and data integrity.
• Robust stainless steel (AISI 304, 2 mm thick, brushed finish) work surface with radiused front edge—designed for ergonomic access, corrosion resistance, and ease of decontamination via standard lab disinfectants.
• Height-adjustable sash and ergonomically optimized internal depth (692 mm) accommodate diverse workflows, including pipetting, cell passaging, and precision weighing.

Sample Compatibility & Compliance

The XLS483F is intended for non-hazardous, non-toxic, and non-pathogenic operations where environmental particulate control—not personnel or environmental protection—is the primary objective. It is routinely deployed in cell culture (non-infectious lines), microbiological assay preparation, pharmaceutical aseptic sampling, optical component handling, semiconductor wafer staging, and cosmetic formulation development. The unit conforms to EN ISO 14644-1:2015 (Class 5), EN 1822-1:2019 (HEPA filter certification), and EU GMP Annex 1 (2022) for Grade A/B background environments. While not rated for biohazard containment (i.e., it lacks negative pressure or recirculation safeguards), its airflow profile and filter integrity support compliance with GLP documentation standards and FDA 21 CFR Part 11–aligned audit trails when integrated with Erlab’s optional digital logging modules.

Software & Data Management

The XLS483F operates via a dedicated microprocessor-based control panel with analog/digital hybrid interface—no embedded OS or cloud connectivity. All operational parameters (fan status, filter delta-P, alarm history) are logged locally with timestamped event records stored in non-volatile memory for ≥12 months. Optional integration with Erlab’s CleanSuite™ DataHub enables export of CSV-formatted logs compatible with LIMS and electronic lab notebooks (ELN). Audit trail functionality satisfies ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) and supports 21 CFR Part 11 compliance when paired with role-based user authentication hardware. No firmware updates require external network access; all configuration changes are performed via physical key-lock interface to preserve system integrity.

Applications

• Non-pathogenic mammalian and insect cell culture—including transfection, cloning, and media preparation—under ISO Class 5 conditions.
• Aseptic transfer and plating in microbiology labs performing environmental monitoring, media fill simulations, or ATCC strain maintenance.
• Weighing of high-purity reference standards, excipients, or APIs in pharmaceutical QC laboratories where airborne particulate interference must be eliminated.
• Assembly and inspection of micro-optical components, MEMS devices, and photonic sensors sensitive to sub-micron contamination.
• Plant tissue culture initiation and meristem isolation in botanical research facilities requiring stringent particulate exclusion.
• Electronics manufacturing support—PCB cleaning verification, solder paste dispensing setup, and bare-die handling prior to encapsulation.

FAQ

Is the XLS483F suitable for handling hazardous biological agents?
No. This is a laminar flow clean bench—not a biosafety cabinet. It provides product protection only and does not protect the operator or environment from aerosolized biohazards.
What is the recommended interval for HEPA filter replacement?
Under typical ISO Class 8 ambient lab conditions, the H14 filter maintains performance for up to 4 years. Replacement timing must be determined empirically using the built-in differential pressure gauge and validated against EN 1822-3 leakage testing.
Can the unit be used for volatile organic compound (VOC) mitigation?
Yes—when equipped with the optional GF4BE+ activated carbon filter module, which adsorbs both polar and non-polar VOCs, acidic gases, and ozone without compromising laminar flow integrity.
Does the XLS483F meet FDA or EMA regulatory expectations for aseptic processing?
It fulfills the environmental classification requirements for Grade A zones when installed in a Grade B background, per EU GMP Annex 1. However, full compliance requires validation of installation, operation, and performance (IQ/OQ/PQ) per ISO 14644-3 and site-specific risk assessment.
Is calibration traceable to national standards?
Airflow velocity and filter integrity testing can be performed using NIST-traceable anemometers and photometers. Erlab provides factory-issued calibration certificates for all instrumentation-grade sensors included with optional monitoring packages.
