Thermo Scientific Herasafe KS Class III Biological Safety Cabinet

Overview

The Thermo Scientific Herasafe KS is a fully enclosed, gas-tight Class III Biological Safety Cabinet engineered for maximum personnel, product, and environmental protection in high-containment biosafety applications. Designed and manufactured in Germany under stringent ISO 14644-1 cleanroom and ISO 13485 medical device quality management standards, the KS cabinet operates under continuous negative pressure with dual HEPA filtration (inlet and exhaust) and glove-port access—ensuring zero exposure to airborne pathogens during manipulation of Risk Group 3 (RG3) and select RG4 agents. Its aerodynamic chamber geometry, coupled with precisely balanced laminar airflow and real-time differential pressure monitoring, maintains stable containment integrity even during extended operation or glove interface use. The system complies with EN 12469:2000, NSF/ANSI 49-2022, and EU Directive 2009/41/EC on the contained use of genetically modified microorganisms—making it suitable for GLP-compliant research, GMP-grade pharmaceutical QC testing, and clinical diagnostic workflows requiring full BSL-3 equivalence.

Key Features

• Fully welded stainless steel (AISI 304) chassis with seamless internal corners for decontamination compatibility and corrosion resistance
• Dual-stage HEPA filtration: Pre-filter + final H14 HEPA (EN 1822-1:2019 compliant) with ≥99.999% efficiency at 0.3 µm and ≥99.995% at MPPS
• Integrated gas-tight glove ports with reinforced butyl rubber gloves (length: 800 mm), ergonomic wrist support, and quick-release clamping mechanism
• Real-time pressure cascade monitoring via three independent digital manometers (cabinet interior, work area, and exhaust plenum)
• Automated decontamination cycle support (e.g., vaporized hydrogen peroxide or formaldehyde), validated per ISO 14644-3 Annex B and ASTM E2994-15
• Touchscreen control panel with audit-trail-enabled event logging (meeting FDA 21 CFR Part 11 requirements for electronic records)
• Energy-optimized blower system with variable-frequency drive (VFD), reducing power consumption by up to 35% versus conventional Class III cabinets

Sample Compatibility & Compliance

The Herasafe KS accommodates standard laboratory equipment including centrifuges (up to 15 mL rotor capacity), microplate readers, pipetting stations, and small-scale bioreactors—within its 1200 × 780 × 630 mm working volume. All materials in contact with the work chamber—including gaskets, glove interfaces, and interior surfaces—are certified non-pyrogenic and compatible with common sterilants (e.g., VHP, chlorine dioxide, peracetic acid). Regulatory alignment includes full traceability to EN 12469:2000 Annex A (performance testing), ISO 14644-1 Class 5 (ISO Class 5 equivalent air cleanliness), and IEC 61010-1:2012 safety certification for laboratory equipment. It supports compliance with national biosafety frameworks including the U.S. CDC/NIH Biosafety in Microbiological and Biomedical Laboratories (BMBL), 6th Edition, and the European Commission’s Directive 2000/54/EC on biological agents at work.

Software & Data Management

The embedded Thermo Scientific CabinetOS firmware provides secure, role-based user access (administrator/operator/auditor), configurable alarm thresholds, and time-stamped operational logs exportable via USB or Ethernet (CSV/Excel format). Audit trails record all parameter changes, door/glove port events, filter saturation alerts, and decon cycle execution—including operator ID, timestamp, and action type. Optional integration with Thermo Fisher’s SampleManager LIMS enables automated cabinet status synchronization and instrument qualification documentation (IQ/OQ/PQ templates available upon request). All software modules are validated per GAMP 5 guidelines and support 21 CFR Part 11 compliance through electronic signatures, data encryption, and immutable log retention.

Applications

• Handling of high-consequence pathogens (e.g., Mycobacterium tuberculosis, Francisella tularensis, SARS-CoV-2 variants) in public health reference labs
• Preparation of sterile radiopharmaceuticals and oncology therapeutics under GMP Annex 1 conditions
• Genetically modified organism (GMO) manipulation in academic and industrial synthetic biology programs
• Antibiotic resistance gene transfer studies requiring absolute physical containment
• Production of viral vectors for gene therapy under ATMP (Advanced Therapy Medicinal Product) regulatory oversight
• Diagnostic assay development for emerging infectious diseases where aerosol generation risk exceeds BSL-2 limits

FAQ

What biosafety level does the Herasafe KS meet?
It is certified as a Class III BSC and functionally equivalent to BSL-3 containment per NIH/CDC BMBL criteria.
Can the cabinet be integrated into a building’s exhaust system?
Yes—it supports hard-ducted exhaust with dedicated ductwork design per ASHRAE 110 and local mechanical code requirements.
Is glove port replacement supported in-field?
Yes—gloves and clamps are field-replaceable using standardized tooling; full replacement kits include validation documentation.
Does the system support remote diagnostics?
Remote troubleshooting is enabled via encrypted Ethernet connection with Thermo Fisher Technical Support (subject to customer network policy approval).
What validation documentation is provided with delivery?
Each unit ships with Factory Acceptance Test (FAT) report, EN 12469 performance certificate, HEPA filter test reports (DOP/NaCl challenge), and installation qualification (IQ) checklist.
