The Fume Hood FH700 is a laboratory ventilation system designed to protect researchers from hazardous fumes, vapors, and particulates during chemical handling operations. This benchtop fume hood provides localized exhaust ventilation to capture and remove airborne contaminants at the source, maintaining safe working conditions in laboratory environments.
The unit features a compact footprint suitable for standard laboratory benches while providing adequate working volume for routine chemical procedures. The FH700 supports workflows requiring containment of volatile organic compounds, acid vapors, and other chemical emissions commonly encountered in analytical chemistry, sample preparation, and small-scale synthesis operations.
How It Works
The FH700 operates on the principle of localized exhaust ventilation, creating a controlled airflow pattern that captures contaminated air at the source and directs it away from the operator. Air is drawn into the hood through the front opening, flows over the work surface, and exits through an exhaust system connected to the rear of the unit.
The containment effectiveness depends on maintaining adequate face velocity - the speed at which air enters the hood opening. This airflow creates a protective barrier that prevents hazardous vapors from escaping into the laboratory environment. The captured air containing chemical contaminants is then directed to appropriate treatment or exhaust systems.
Proper operation requires consideration of factors including sash height, placement of equipment within the hood, and prevention of cross-drafts that could disrupt the protective airflow pattern.

Practical Tips
Position the hood away from high-traffic areas and air supply vents to minimize cross-drafts that could disrupt protective airflow patterns.
Why: Cross-drafts can significantly reduce containment effectiveness and allow hazardous vapors to escape into the laboratory environment.
Test face velocity monthly using a calibrated anemometer at multiple points across the hood opening, documenting results for compliance records.
Why: Regular monitoring ensures the exhaust system maintains adequate airflow for proper chemical containment.
Clean the work surface with appropriate solvents after each use and inspect for chemical damage or buildup that could affect airflow.
Why: Chemical residues can create contamination sources and surface deterioration can compromise the structural integrity of the hood.
Keep the sash at the lowest practical position during operations and never place your head inside the hood opening.
Why: Lower sash positions improve containment effectiveness and reduce the risk of exposure to chemical vapors.
If containment appears compromised, immediately check for blocked exhaust connections, damaged sash mechanisms, or changes in building ventilation.
Why: Rapid identification and correction of airflow problems prevents exposure incidents and maintains laboratory safety.
Document all hood performance tests including face velocity measurements, containment verification results, and maintenance activities.
Why: Comprehensive records demonstrate due diligence in safety management and support regulatory compliance documentation.
Elevate large equipment on stands within the hood to allow airflow underneath and prevent dead air zones.
Why: Proper airflow circulation around equipment ensures consistent capture of vapors and maintains containment effectiveness throughout the work area.

Background reading relevant to this product:
What face velocity should be maintained for proper containment?
Typical face velocity requirements range from 0.4-0.6 m/s (80-120 feet per minute) depending on the application and chemicals used. Consult product datasheet for specific airflow requirements and conduct regular testing with calibrated instruments.
How do I verify the hood is providing adequate protection?
Perform containment testing using tracer gases, smoke visualization, or other approved methods. Regular face velocity measurements and annual containment testing by qualified personnel are recommended to ensure continued protection.
What types of chemicals can be safely used in this hood?
The hood is suitable for most common laboratory chemicals including organic solvents, acids, and bases. Avoid highly toxic substances, radioactive materials, or chemicals requiring specialized treatment unless specifically validated for such use.
How should equipment be positioned within the hood?
Place equipment at least 15 cm back from the front edge and avoid blocking airflow patterns. Large equipment should be elevated on stands to allow airflow underneath, and heating devices should be positioned to minimize thermal disruption of containment.
What exhaust system requirements are needed?
The exhaust system must provide adequate airflow to maintain proper face velocity and handle the air volume processed by the hood. Consult with HVAC professionals to ensure compatibility with existing building ventilation systems.
How often does the hood require maintenance?
Monthly visual inspections, quarterly airflow testing, and annual comprehensive performance evaluations are recommended. Clean work surfaces regularly and inspect for chemical damage or wear that could affect performance.
Can multiple users work at this hood simultaneously?
The 115 cm width can accommodate multiple users, but proper work practices should be maintained to avoid disrupting airflow patterns. Coordinate activities to prevent interference and maintain safe chemical handling procedures.
What are the electrical requirements for installation?
Electrical requirements depend on any integrated lighting or monitoring systems. Consult product datasheet for specific voltage and amperage requirements, and ensure installation meets local electrical codes.
