External Ducted Hood with 2 Hand Passages
₹56,568.00
The StemAids External Ducted Hood with 2 Hand Passages is a laboratory fume extraction hood designed to capture and exhaust compatible chemical vapours, fumes, odours, and airborne contaminants to an external ventilation system. It is suitable for chemistry laboratories, schools, colleges, research facilities, pharmaceutical labs, industrial QC labs, and institutional science laboratories where ducted extraction is preferred.
Product Description
The StemAids External Ducted Hood with 2 Hand Passages provides a controlled working enclosure for handling compatible chemicals and laboratory processes that may release vapours or fumes. The two ergonomic hand passages allow the operator to work inside the hood while helping maintain a defined air capture zone.
Unlike ductless filtration hoods, this external ducted hood is designed to connect with an exhaust duct and ventilation system so contaminated air can be discharged outside the laboratory. It is useful for reagent preparation, chemical handling, sample treatment, solvent work, demonstrations, and routine laboratory procedures where external extraction is required.
Important Note: This is a chemical fume extraction hood, not a biological safety cabinet. It should not be used for infectious biological materials, radioactive substances, explosive materials, or highly toxic chemicals unless the full system design, ventilation rate, ducting, and safety controls are approved by qualified laboratory safety personnel.

- Laboratory workflows requiring external exhaust instead of recirculation
Safety and Handling Guidelines
- Use only after proper ducting and exhaust installation by qualified personnel.
- Verify airflow before each use according to laboratory SOP.
- Do not use the hood if the exhaust fan or duct system is not working.
- Do not use for biological containment unless the equipment is specifically certified for that purpose.
- Do not use for explosive, radioactive, highly toxic, or unknown substances without formal risk assessment.
- Keep the working opening, hand passages, and airflow path clear.
- Do not overload the enclosure with unnecessary bottles or apparatus.
- Wear suitable PPE such as gloves, goggles, lab coat, and respiratory protection if required by SOP.
- Keep ignition sources away when working with flammable vapours.
- Follow SDS instructions, institutional chemical safety rules, and local ventilation regulations.
- Clean spills immediately using a compatible laboratory-safe procedure.
- Schedule regular airflow testing, duct inspection, and fan maintenance.
Quality and E-E-A-T Notes
The StemAids External Ducted Hood with 2 Hand Passages supports evidence-based laboratory safety by helping capture fumes at the source and direct them toward an external exhaust system. For reliable protection, laboratories should maintain airflow verification records, duct inspection logs, chemical compatibility reviews, SDS documentation, and SOP-based user training.
FAQ
1. What is the StemAids External Ducted Hood with 2 Hand Passages used for?
It is used for handling compatible chemicals and laboratory procedures that may release vapours, fumes, odours, or airborne contaminants requiring external exhaust.
2. Does this hood require ducting?
Yes, it is an external ducted hood and must be connected to a suitable exhaust duct and ventilation system.
3. What are the two hand passages for?
The two hand passages allow the operator to work inside the enclosure while helping maintain a controlled air capture zone.
4. Is this a ductless filtration hood?
No, this is a ducted hood. It extracts air through an external duct system instead of recirculating filtered air back into the room.
5. What sizes are available?
Common width options include 600 mm, 900 mm, 1200 mm, and 1500 mm depending on the selected model.
6. Can it be used for solvent work?
Yes, it can be used for compatible solvent vapour extraction when the ducting, exhaust fan, airflow, and laboratory safety controls are suitable.
7. Can it be used for powders?
It may be used for certain powder-handling procedures only if the external exhaust and filtration/collection arrangement are designed for particle control.
8. Is it suitable for biological samples?
No, it should not be used as a biological safety cabinet unless the specific system is certified for biological containment.
9. What should be checked before use?
Check exhaust fan operation, airflow direction, duct connection, hood cleanliness, chemical compatibility, and PPE requirements before starting work.
10. What happens if airflow is weak?
Work should be stopped immediately. The hood should not be used until airflow, fan operation, and ducting are inspected and corrected.
11. Can it be installed anywhere in the laboratory?
No, installation must consider duct routing, exhaust discharge location, electrical supply, bench strength, airflow disturbance, and regulatory ventilation requirements.
12. How should the hood be maintained?
Clean the work area regularly, inspect panels and seals, verify airflow, check ducting, maintain the exhaust fan, and document all safety checks according to laboratory SOP.
