Dispensing Booth
LENGE Dispensing Booth (also known as Weighing Booth or Sampling Booth) provides a safe, contained environment for weighing, sampling, and dispensing operations in pharmaceutical and biopharma facilities. It creates a negative pressure zone with unidirectional laminar airflow to protect operators from hazardous dust and powders while preventing cross-contamination and maintaining GMP compliance.

FAQs for Better Results
What is a Dispensing Booth (Weighing Booth/Sampling Booth)?
A Dispensing Booth is a localized containment system that provides a negative pressure environment with unidirectional laminar airflow. It protects operators from hazardous dust and powders during weighing, sampling, and dispensing of APIs, excipients, or potent compounds, while preventing cross-contamination into the surrounding cleanroom.
How does the negative pressure work in a Dispensing Booth?
Negative pressure draws airborne particles inward toward the filters and away from the operator’s breathing zone. This containment, combined with HEPA-filtered unidirectional flow (0.45 m/s ±20%), creates a safe, ISO Class 5-equivalent work area while maintaining background cleanroom integrity.
What filtration system is used?
Multi-stage filtration includes:
- G4 pre-filter (panel type)
- F8 bag filter (comfort filter)
- Gel-sealed mini-pleated H14 HEPA filter (99.995% efficient @ 0.3 μm)
Optional ULPA filters are available for higher efficiency.
What materials are used in LENGE Dispensing Booths?
Fully welded SUS304 or SUS316L stainless steel chambers with rounded coved corners, seamless interiors, and clean external finishes. This GMP-compliant design minimizes particle traps and simplifies cleaning/validation.
Are Dispensing Booths customizable?
Yes — all units are built to your URS (User Requirements Specification). We customize dimensions, layout, power, controls, additional sensors (RH/temperature), electrical outlets, and features to match your exact process needs.
What cleanliness level does a Dispensing Booth achieve?
It provides an aseptic work zone equivalent to ISO Class 5 (or better) within the booth, while the background cleanroom can be Class D or higher. The unidirectional airflow ensures particle-free conditions at the work surface.
What controls and safety features are included?
Standard microprocessor control panel with differential pressure monitoring, LED indicators, emergency stop, fault alarms, power outlets, and RH/temperature sensors. Magnetic interlocks and auto-start functions enhance safety and usability.
What applications are Dispensing Booths best suited for?
Primarily for pharmaceutical weighing, sampling, and dispensing of powders — especially in solid dosage, API manufacturing, biopharma, and R&D/QC areas where personnel protection and contamination control are critical.
