Chemihood’plus filtering ventilation hood

The StemAids Chemihood Plus Filtering Ventilation Hood is a ductless molecular filtration hood designed for safer handling of compatible chemicals, vapours, solvents, acids, and laboratory reagents without the need for external duct connection. It is suitable for chemistry laboratories, schools, colleges, pharmaceutical labs, research facilities, conservation labs, industrial QC labs, and institutional science laboratories.

Product Description

The StemAids Chemihood Plus Filtering Ventilation Hood provides a controlled working area for chemical handling by extracting harmful vapours through a molecular filtration system. The hood is designed to offer user protection, clear visibility, ergonomic handling, and convenient laboratory placement without the complexity of external exhaust ducting.

The hood body is made from transparent optical methacrylate, helping users see the complete working area clearly during operation. Its 7° inclined front panel improves working posture, while the two arm-access passages allow safer manipulation of chemicals and apparatus inside the enclosure.

The filtration unit uses application-specific activated charcoal filters. Filter selection must be based on the chemicals being handled, such as solvents, acids, mixed vapours, or other compatible vapour types. The hood includes visual and acoustic indicators for correct operation and filter saturation monitoring, supporting safer laboratory workflows.

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

• Do not exceed the filter capacity or approved chemical quantity.
• Monitor filter saturation and replace filters on time.
• Do not block the air intake, hand passages, or filter outlet.
• Use suitable PPE such as gloves, safety goggles, lab coat, and respiratory protection if required by SOP.
• Keep ignition sources away when working with flammable vapours.
• Clean accidental spills immediately using a compatible laboratory-safe method.
• Follow SDS instructions, institutional chemical safety rules, and local laboratory regulations.
• Allow only trained personnel to install filters, operate the hood, and approve chemical use.

Quality and E-E-A-T Notes

The StemAids Chemihood Plus Filtering Ventilation Hood supports evidence-based laboratory safety through controlled molecular filtration, correct filter selection, airflow-based vapour capture, filter saturation monitoring, and documented maintenance.

FAQ

1. What is the StemAids Chemihood Plus Filtering Ventilation Hood used for?

It is used for safer handling of compatible chemical vapours, solvents, acids, reagents, and laboratory samples under ductless filtered ventilation.

2. Does this hood require external ducting?

No, it is a ductless molecular filtration hood. It filters air through selected filters and returns filtered air to the room.

3. What filter does the hood use?

It uses activated charcoal filters selected according to the handled products, such as solvent filters, acid filters, or mixed vapour filters.

4. Is the filter included with the hood?

Filter supply depends on the selected configuration. In many cases, the correct filter must be selected separately according to the chemical application.

5. What sizes are available?

Common Chemihood Plus sizes include 600 mm, 900 mm, and 1200 mm width models.

6. What is the airflow capacity?

The filtration ventilation system provides airflow capacity of approximately 100 / 250 m³/h depending on operation and configuration.

7. What is the acoustic level?

The reference filtration system has an acoustic level of approximately 45 dB.

8. Does it have a filter saturation alarm?

Yes, the hood includes a visual and acoustic filter saturation indicator based on air velocity through the activated charcoal filter.

9. Is it suitable for biological samples?

No, this hood 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 when the correct solvent filter is installed and the chemical quantity is within approved safety limits.

11. Can it be used for acid vapours?

Yes, acid vapours can be handled only with a suitable acid or acid-compatible activated charcoal filter.

12. How should the hood be maintained?

Keep the hood clean, monitor operating hours, check filter saturation, replace filters as required, inspect panels and seals, verify airflow, and document maintenance according to laboratory SOP.
