Erlab Captair Bio 321 Smart Vertical Laminar Flow Clean Bench

Overview

The Erlab Captair Bio 321 Smart is a vertically oriented, unidirectional laminar flow clean bench engineered for contamination-sensitive non-hazardous applications in molecular biology, cell culture, PCR setup, and sterile sample handling. Unlike biological safety cabinets (BSCs), which protect both operator and sample via recirculated and exhausted airflow, the Captair Bio 321 Smart delivers ISO Class 5 (formerly Class 100) clean air exclusively to the work surface—ensuring particulate-free conditions for critical aseptic procedures while operating without ducted exhaust or external venting. Its core architecture employs a high-efficiency particulate air (HEPA) filter (EN 1822 H14, ≥99.995% @ 0.1 µm) positioned above the work area, coupled with a low-turbulence, vertically downward airflow profile (0.3–0.5 m/s uniform velocity across the working plane). This design eliminates cross-contamination risks between samples and supports reproducible results in nucleic acid amplification workflows where amplicon carryover must be rigorously controlled.

Key Features

• SmartTouch™ intuitive interface with real-time airflow velocity monitoring, filter life estimation, and programmable UV lamp scheduling (pre- and post-use cycles)
• Height-adjustable work surface (965–1059 mm range) accommodating seated and standing ergonomics—compliant with ISO 11228-1 and EN 527-1 workstation anthropometric guidelines
• Integrated LED lighting system (≥500 lux at work surface) with flicker-free operation and color rendering index (CRI) >85 for accurate visual inspection of gels, plates, and pipette tips
• Double-walled stainless steel construction (AISI 304) with seamless welded corners and antimicrobial epoxy-coated base pan for chemical resistance and ease of decontamination
• No external ducting required: self-contained recirculation system with pre-filter + HEPA filtration enables flexible laboratory placement and reduced installation complexity
• Optional integrated ethanol-resistant touchscreen and Ethernet-enabled remote diagnostics (via Erlab’s CloudConnect platform) for centralized fleet management

Sample Compatibility & Compliance

The Captair Bio 321 Smart is validated for use with standard PCR consumables—including 96-well plates, strip tubes, master mix reagents, and enzymatic reaction setups—without airflow disruption or static-induced droplet dispersion. It is not designed for handling volatile organic compounds, aerosol-generating procedures, or pathogenic agents requiring biosafety containment (i.e., it does not meet NSF/ANSI 49 or EN 12469 requirements for BSCs). The unit conforms to ISO 14644-1:2015 (Class 5 cleanroom performance), IEC 61000-6-3 (EMC emissions), and IEC 61000-6-2 (immunity). All electrical components comply with CE marking directives (2014/30/EU, 2014/35/EU), and UV lamp intensity adheres to EN 60335-2-60 for safe human exposure limits during interlocked operation.

Software & Data Management

The Captair Bio 321 Smart features embedded firmware supporting GLP-compliant audit trails: all operational events—including UV activation timestamps, airflow calibration logs, filter replacement records, and user login sessions—are timestamped, immutable, and exportable as CSV or PDF. When connected to Erlab’s CloudConnect service (optional), data syncs to a secure, ISO 27001-certified cloud repository with role-based access control and 21 CFR Part 11–compatible electronic signatures. Local configuration and calibration parameters are stored in non-volatile memory and survive power loss. Firmware updates are delivered via signed OTA packages to ensure integrity and traceability.

Applications

• Pre-PCR reagent preparation and master mix assembly in low-biomass detection workflows
• Plasmid transformation and bacterial colony picking under particle-controlled conditions
• Microinjection and embryonic stem cell passaging requiring laminar sterility
• Quality control testing of pharmaceutical excipients and sterile medical device components
• Educational lab instruction in molecular techniques where biosafety level 1 (BSL-1) containment suffices
• Environmental microbiology sample dilution and membrane filtration setups

FAQ

Does the Captair Bio 321 Smart provide personnel protection?

No. It is a sample-protective clean bench only; it does not protect the operator from hazardous aerosols or vapors.
Can it be used for mycoplasma testing or viral culture?

No. These applications require certified Class II biological safety cabinets per EN 12469 or NSF/ANSI 49.
What maintenance intervals are recommended for the HEPA filter?

Filter replacement is advised every 18–24 months under typical usage (8 hrs/day, ISO Class 5 ambient environment); actual lifespan is monitored in real time via the SmartTouch™ interface.
Is validation documentation available for IQ/OQ protocols?

Yes—Erlab provides standardized Installation Qualification (IQ) and Operational Qualification (OQ) templates aligned with ISO/IEC 17025 and GMP Annex 1 expectations.
Does the unit support integration with laboratory information management systems (LIMS)?

Via optional CloudConnect API, yes—supporting RESTful endpoints for event logging, status polling, and automated certificate generation.
