Labopur Class 2 Filtration Hood

The StemAids Labopur Class 2 Filtration Hood is a ductless recirculating laboratory hood designed for safer handling of compatible chemical vapours, powders, and laboratory substances under controlled filtration conditions. It is suitable for chemistry laboratories, pharmaceutical labs, research facilities, schools, colleges, industrial QC laboratories, and institutional science laboratories where filtered air recirculation is required.

Product Description

The StemAids Labopur Class 2 Filtration Hood is designed to capture and filter hazardous vapours or particles generated during laboratory handling. Instead of exhausting air outside through ducting, the hood draws contaminated air through a suitable filter system and returns filtered air back into the room.

This Class 2 filtration hood is based on NF X 15-211 ductless filtration hood principles. Depending on the chemical or powder handled, it can be used with activated carbon filters for vapours, HEPA filters for particles, or combined filtration configurations. Filter selection must always be matched with the chemicals, quantities, exposure risk, and laboratory safety assessment.

Important Note: This is a chemical filtration hood, not a Class II biological safety cabinet. It is intended for compatible chemical vapour or particle filtration applications and should not be used for biological containment unless the selected model is specifically certified for that purpose.

Safety and Handling Guidelines

• Always verify chemical compatibility before using the hood.
• Use only the correct filter type for the substances being handled.
• Do not use the hood for unknown, highly toxic, explosive, radioactive, or incompatible substances without a formal risk assessment.
• Do not use for biological containment unless the hood is specifically certified for that purpose.
• Do not exceed the chemical quantity or exposure limit allowed by the filter capacity.
• Check filter saturation regularly using the recommended testing method.
• Replace saturated filters before continuing laboratory work.
• Do not block airflow slots, hand openings, exhaust area, or filter modules.
• Wear suitable PPE such as gloves, goggles, lab coat, and respiratory protection if required by SOP.
• Keep ignition sources away when handling flammable vapours.
• Follow SDS instructions, institutional chemical safety rules, and local regulations.
• Allow trained personnel to service, test, and replace filters.

Quality and E-E-A-T Notes

The StemAids Labopur Class 2 Filtration Hood supports evidence-based laboratory safety by combining controlled airflow, matched filtration, filter-saturation monitoring, and documented maintenance. For reliable protection, users should perform chemical compatibility checks, follow SDS guidance, maintain filter records, monitor airflow, and replace filters according to verified saturation results and laboratory SOP.

FAQ

1. What is the StemAids Labopur Class 2 Filtration Hood used for?

It is used for filtered handling of compatible chemical vapours, powders, reagents, and laboratory substances under ductless recirculating airflow.

2. What does Class 2 mean in this filtration hood?

In this context, Class 2 refers to the NF X 15-211 ductless filtration hood classification. It should not be confused with a Class II biological safety cabinet.

3. Is this hood ductless?

Yes, it is a ductless recirculating filtration hood. The air is filtered through suitable filters and returned to the laboratory room.

4. What filters can be used?

Filter options may include activated carbon filters for organic vapours, polyvalent filters for mixed vapours, formaldehyde filters, ammonia filters, and HEPA filters for suitable particle applications.

5. Can it be used for solvents?

It can be used for compatible solvent vapours only when the correct activated carbon filter is selected and the quantity handled is within safe filter capacity.

6. Can it be used for powders?

Yes, powder handling may be possible when the hood is equipped with an appropriate particle or HEPA filtration system.

7. How often should the filter be checked?

For Class 2 NF X 15-211 filtration hoods, activated carbon filter saturation should be checked regularly, with 60-hour checking intervals commonly referenced in operating guidance.

8. Does the hood need external ducting?

No, the main advantage of this type of hood is ductless operation. However, laboratory ventilation and room air quality must still be considered.

9. Is it suitable for biological samples?

No, it should not be used as a biological safety cabinet unless the specific model is certified for biological containment.

10. What airflow is required?

Reference configurations operate with an average face velocity of approximately 0.4 to 0.6 m/s. The airflow should be verified before use.

11. What happens if the filter is saturated?

A saturated filter must be replaced before further chemical handling. Continuing work with a saturated filter may release harmful vapours back into the laboratory.

12. Who should select the correct filter?

Filter selection should be done by trained laboratory safety personnel or technical staff using the chemical list, SDS data, concentration, quantity, and exposure risk.
