SH Scientific’s Mobile Fume Hood: Tested, Proven, and Unmatched in Lab Safety
In the dynamic landscape of laboratory research, maintaining a safe working environment for scientists is essential. SH Scientific has introduced an advanced mobile fume hood that exemplifies superior air purification capabilities. Tested by the Korea Testing Laboratory (KTL)—a Korean government-run institution similar to the Nationally Recognized Testing Laboratory (NRTL) in the USA, recognized for its rigorous evaluation standards and highest standard testing procedures—this fume hood demonstrates exemplary performance in removing volatile organic compounds (VOCs).
Rigorous Evaluation for VOC Removal
The Korea Testing Laboratory employed a comprehensive suite of sophisticated methodologies, including Automated Thermal Desorption Gas Chromatography/Mass Spectrometry (ATD-GC/MS), to evaluate the VOC removal performance of the fume hood. This testing approach involved multiple stages and precise conditions to ensure a thorough assessment of the unit’s capabilities:
- Inlet Sampling: A mixture of VOC gases, including Benzene, Toluene, Ethylbenzene, Xylene, and Styrene, was introduced into a mixing chamber positioned precisely in front of the Equipment Under Test (EUT). The VOC gas flow rate was meticulously controlled and maintained to provide a consistent and reproducible assessment of the fume hood’s filtration effectiveness.
- Outlet Sampling: Exhaust samples were collected from the outlet after passing through the fume hood’s multi-stage filtration system. The system operated at its maximum capacity (Level 10), with an exhaust flow rate of 1 L/min. The sampling was designed to accurately reflect the filtration performance under conditions simulating real laboratory use.
- Advanced Analysis: The collected sorbent tubes underwent Automated Thermal Desorption followed by Gas Chromatography/Mass Spectrometry (ATD-GC/MS) analysis. This advanced analytical technique quantified the concentration of VOCs remaining after filtration, revealing an impressive reduction efficiency across all tested compounds.
The results of these rigorous evaluation processes were phenomenal, demonstrating that SH Scientific’s mobile fume hood is second to none in its class. The unit achieved exceptionally high removal efficiencies—99.1% for Benzene and Toluene, 96.2% for Ethylbenzene, 93.1% for Xylene, and 90.1% for Styrene—making it a top-tier solution for VOC management in laboratory settings. These results confirm that SH Scientific’s mobile fume hood delivers unparalleled air purification, providing laboratories with assurance, reliable performance, and superior safety.

Tailored for Diverse Laboratory Applications
The mobile fume hood addresses the diverse needs of laboratory professionals working with various applications. Whether researchers are using tube furnaces, muffle furnaces, drying ovens, or vacuum pumps that emit hazardous VOCs, the fume hood offers a controlled, contaminant-free workspace. It is particularly advantageous for laboratories with limited ventilation systems, offering an affordable and effective alternative for enhancing lab safety.
Application in Muffle Furnaces, Tube Furnaces, Drying Ovens, and Vacuum Pumps
The need for efficient ventilation is especially crucial when researchers use muffle or tube furnaces, as these often generate harmful VOCs and other airborne contaminants. SH Scientific’s mobile fume hood is engineered to offer an effective solution in such scenarios, ensuring the safety of personnel and maintaining the quality of the laboratory environment.
- Muffle Furnaces: These furnaces are widely used for heat treatment, annealing, and material testing, often resulting in the release of hazardous gases. The mobile fume hood captures these emissions directly at the source, utilizing its flexible arm and adjustable hood to prevent hazardous substances from dispersing into the laboratory air, thereby protecting researchers from exposure.
- Tube Furnaces: These furnaces are commonly employed for processes like chemical vapor deposition (CVD), calcination, and material synthesis, which can emit VOCs and other harmful gases. The mobile fume hood’s three-level filtration system—including a pre-filter, HEPA filter, and VOC filter—effectively removes these emissions, ensuring that the laboratory remains a safe environment. Its ductless design allows for convenient placement near the furnace, providing targeted fume extraction without requiring complex ventilation setups.
- Vacuum Pumps: Vacuum pumps, often used in laboratory settings for various purposes, can also emit hazardous VOCs during their operation. The mobile fume hood efficiently captures these emissions, ensuring that the laboratory environment remains safe and free of contaminants.
- Drying Ovens: Drying ovens, used to remove moisture from samples, can also emit hazardous VOCs depending on the materials being processed. The mobile fume hood effectively captures these emissions, ensuring a clean and safe laboratory environment.
- Direct Capture at Source: The flexible arm is particularly beneficial for furnace applications, as it can be positioned close to the emission source for immediate fume capture, minimizing the risk of airborne contaminants spreading throughout the laboratory.
- Adjustable Airflow for Specific Applications: Both muffle and tube furnace processes may require different levels of airflow depending on the experiment. The mobile fume hood’s adjustable airflow control allows researchers to fine-tune the exhaust rate, ensuring effective fume capture while maintaining stable experimental conditions.
In laboratories where conventional fixed fume hoods are impractical or unavailable, SH Scientific’s mobile fume hood offers an indispensable safety solution. Its compact and mobile design allows it to be positioned precisely where needed, making it an ideal choice for labs that use high-temperature furnaces and require effective VOC management.
Enhancing Lab Safety and Comfort
For laboratories dealing with VOC emissions, SH Scientific’s mobile fume hood offers both enhanced safety and improved working conditions. This compact, portable unit brings advanced fume extraction capabilities to labs lacking access to large-scale ventilation systems. Its user-friendly maintenance, including straightforward filter replacement, makes it a practical choice for laboratories aiming to maintain high safety standards.
