Premium Single-Operator Vertical Laminar Flow Cabinet
Premium Single-Operator Vertical Laminar Flow Cabinet — ToronLFCab™ SO-P Series
ToronLFCab™ SO-P is a vertical downflow laminar flow cabinet designed for laboratory operations requiring a Class 100 (ISO 5) clean working environment. This clean bench delivers HEPA-filtered air vertically downward across the work surface, creating a positive-pressure airflow curtain at the open front that prevents unfiltered ambient air from entering the work zone such as protecting samples, cultures, and sensitive materials from particulate contamination during open handling operations.
Available in three working widths — ToronLFCab™ SO-1P (830 mm), ToronLFCab™ SO-2P (1300 mm), and ToronLFCab™ SO-3P (1800 mm) — the ToronLFCab™ SO-P series provides a scalable selection of laminar air flow cabinets for single-operator benchtop work through wider multi-step workflow configurations. All three models share the same core performance specifications: wind speed 0.3–0.6 m/s, noise at or below 67 dB, vibration half peak value within 5 µm across all three axes, and illuminance at or above 300 Lux. A cold-rolled steel housing with electrostatic spray finish and SUS304 stainless steel worktable are standard across the lineup.
The LCD control system with touch-type switches governs all operational functions, including six-stage wind speed adjustment, independent UV sterilization lamp control, and a UV timer supporting sterilization cycles from 0 to 999 minutes. A medium-efficiency pre-filter upstream of the HEPA extends HEPA service life by capturing larger particles before they reach the final filter — reducing replacement frequency and long-term operating cost. As a vertical laminar flow cabinet designed for single-sided operation, the ToronLFCab™ SO-P series is suited to microbiological work, pharmaceutical compounding preparation, electronic component handling, and any laboratory workflow where a reproducible Class 100 clean bench environment is required.
Premium Single-Operator Vertical Laminar Flow Cabinet — ToronLFCab™ SO-P Series Applications
The ToronLFCab™ SO-P serves laboratory, pharmaceutical, electronics, and research environments where a Class 100 particulate-free working zone is required for open sample handling:
- Microbiological Culture Work: aseptic transfer of microbial cultures, preparation of culture media, and inoculation of agar plates in a laminar flow cabinet environment that protects samples from airborne contamination
- Pharmaceutical Compounding Preparation: preparation of non-hazardous pharmaceutical compounds, sterile product handling, and reagent preparation in a Class 100 clean bench environment aligned with USP compounding guidelines
- Cell and Tissue Culture: aseptic handling of cell lines, primary cultures, and tissue samples requiring a particulate-controlled work zone without the operator-protection features of a biosafety cabinet
- Electronic Component Assembly and Inspection: handling of semiconductor components, optical elements, sensors, and precision electronic assemblies where particulate contamination on surfaces causes functional failures
- Food Science and Quality Control: aseptic preparation of microbiological test samples, culture plate inoculation, and sterile reagent handling in food safety testing laboratories
- Analytical Chemistry: preparation of analytical standards, gravimetric samples, and trace-level specimens where airborne particulate contamination would introduce measurement error
- Academic and Research Laboratories: general-purpose laminar air flow cabinet applications for multi-user research facilities requiring a reproducible clean working environment for sensitive protocols

Theory and Method
Vertical Laminar Downflow and Clean Zone Formation
The ToronLFCab™ SO-P operates on a vertical laminar downflow principle. HEPA-filtered air is introduced at the top of the working chamber and flows downward across the entire work surface at a controlled velocity of 0.3 to 0.6 m/s. This downward airflow forms a near-laminar, particle-free curtain across the open work zone. At the open front face of the cabinet, the downward flow velocity creates a positive-pressure barrier that deflects ambient laboratory air away from the work surface, preventing unfiltered particles from entering the clean zone from the front.
This vertical quasi-closed table design maintains Class 100 (ISO 5) conditions within the working area so a particle count of no more than 100 particles per cubic foot at 0.5 µm or larger. The airflow design specifically excludes horizontal flow configurations, which manage contamination differently and are suited to distinct application categories. For sample-protection applications requiring vertical downflow clean air delivery, the ToronLFCab™ SO-P provides the correct airflow geometry.
HEPA Filtration and Pre-Filter System
The HEPA filter (one per unit across all three models) captures particles at 0.3 µm and larger with a minimum efficiency of 99.97%, the performance threshold that defines HEPA classification. Upstream of the HEPA, a medium-efficiency pre-filter captures larger airborne particles before they reach the final filter stage. This two-stage filtration approach reduces the particulate loading on the HEPA, extending its service life meaningfully compared to single-stage HEPA-only configurations. For laboratories managing ongoing laminar air flow cabinet operating costs, the extended HEPA service life that the pre-filter enables has a direct and measurable impact on filter replacement frequency and annual maintenance expenditure.
Airflow Velocity Control and Noise Performance
The centrifugal fan drives airflow through the filtration system at a steady rotational speed with low acoustic output. Six-stage wind speed adjustment (controlled through the LCD touchscreen interface) allows operators to select the airflow velocity that best matches their protocol requirements within the 0.3 to 0.6 m/s operating range. Noise is held at or below 67 dB across all three models and all fan speed settings, and vibration half peak values remain within 5 µm in all three axes — specifications that are particularly relevant for electronic component handling and precision analytical work where fan-induced vibration could affect sample stability or measurement accuracy.
UV Sterilization System
An independently controlled UV sterilization lamp is standard across all three models, with a programmable sterilization timer ranging from 0 to 999 minutes. The UV lamp and the working lamp operate on independent controls, allowing sterilization cycles to be run before or after work sessions without activating the work lighting. The independently timed UV cycle supports consistent pre-use decontamination protocols without requiring operator presence during the sterilization period.
