Mini air recirculation hood Labopur H70

The StemAids Mini Air Recirculation Hood Labopur H70 is a compact ductless laboratory filtration hood designed for safer handling of small quantities of compatible chemicals, vapours, reagents, and laboratory samples. It is suitable for schools, colleges, chemistry laboratories, pharmaceutical labs, research facilities, quality-control laboratories, and compact laboratory workspaces where external ducting is not practical.

Product Description

The StemAids Labopur H70 Mini Air Recirculation Hood is designed to capture chemical vapours inside a compact working enclosure and pass them through a selected activated carbon filter before returning filtered air to the laboratory room. Its small footprint makes it useful for limited bench spaces, teaching laboratories, preparation rooms, and routine chemical handling stations.

The hood is built with a steel structure, epoxy-coated finish, transparent PMMA side walls, ergonomic hand passages, and a swing-opening front panel for full access to the interior. It is suitable for controlled manipulation of compatible products when fitted with the correct filter type.

Important Note: This is a ductless chemical filtration hood, not a biological safety cabinet. It should not be used for infectious biological materials, radioactive substances, explosive vapours, highly toxic unknown chemicals, or applications outside the approved filter compatibility.

Safety and Handling Guidelines

• Always verify chemical compatibility before using the hood.
• Use only the correct filter type for the chemical vapours being handled.
• Do not operate the hood without a suitable installed filter.
• Do not use with explosive, radioactive, infectious, highly toxic, or unknown substances without formal risk assessment.
• Do not exceed the filter capacity or permitted chemical quantity.
• Do not block the air intake, outlet, hand passages, or filter area.
• Check filter saturation regularly using the recommended reagent-tube method.
• Replace saturated, expired, damaged, or incompatible filters immediately.
• Wear suitable PPE such as gloves, safety goggles, and lab coat during operation.
• Keep ignition sources away when handling flammable vapours.
• Follow SDS instructions, institutional safety rules, and local laboratory regulations.
• Allow only trained users to operate, clean, and maintain the hood.

Quality and E-E-A-T Notes

The StemAids Mini Air Recirculation Hood Labopur H70 supports evidence-based laboratory safety by combining controlled airflow, chemical-specific activated carbon filtration, visible work enclosure, and filter saturation checking. For dependable protection, laboratories should maintain chemical compatibility records, filter usage logs, saturation-test records, SDS references, airflow checks, and SOP-based user training.

FAQ

1. What is the StemAids Mini Air Recirculation Hood Labopur H70 used for?

It is used for safer handling of small quantities of compatible chemical vapours, reagents, and samples inside a ductless filtered work enclosure.

2. Does the Labopur H70 require external ducting?

No, it is a ductless air recirculation hood. Air is filtered through a suitable activated carbon filter and returned to the laboratory room.

3. What are the external dimensions?

The external dimensions are approximately 505 × 605 × 485 mm, L × H × D.

4. What are the internal dimensions?

The internal dimensions are approximately 455 × 410 × 445 mm, L × H × D.

5. What is the airflow rate?

The airflow rate is approximately 170 m³/hour.

6. Is the filter included?

The filter is generally not supplied as standard. A suitable activated carbon filter must be selected separately according to the chemical application.

7. Which filters can be used?

Compatible filter options may include organic vapour filters, common laboratory chemical filters, formaldehyde filters, ammonia filters, or other application-specific activated carbon filters.

8. How is filter saturation checked?

The hood includes a side control port that allows the use of specialised reagent tubes and a manual pump to check filter efficiency or saturation.

9. Is this hood suitable for biological work?

No, this is not a biological safety cabinet and should not be used for infectious biological containment.

10. Can it be used for solvent vapours?

Yes, compatible solvent vapours can be handled only when the correct organic vapour filter is installed and the quantity handled is within approved safety limits.

11. What is the noise level?

The fan noise level is approximately 57 dB(A), excluding airflow noise.

12. How should the hood be maintained?

Keep the hood clean, inspect the PMMA panels, verify airflow, monitor filter usage, check filter saturation, replace filters on time, and document maintenance according to laboratory SOP.
