Product Description

Laboratory Cleanroom Project

This laboratory cleanroom project was designed for a testing and research laboratory in Jakarta, Indonesia. The client needed a controlled laboratory environment for sample preparation, routine testing, clean handling, biosafety cabinet operation, and cleaner movement of personnel and materials.

STJh Cleanroom provided a complete laboratory cleanroom solution including cleanroom layout design, laboratory workstations, HEPA filtration, laminar airflow areas, pressure zoning, gowning and personnel entry, pass box sample transfer, biosafety cabinet integration, temperature and humidity control, environmental monitoring, and installation support.

The project was designed as a practical laboratory cleanroom, not only a clean-looking room. The layout considered daily sample movement, operator workflow, equipment placement, cleaning access, material transfer, room visibility, and future laboratory expansion.

Project Background

Laboratory cleanrooms require a controlled environment for sample preparation, testing, clean handling, and sensitive laboratory procedures. Unlike ordinary laboratories, cleanroom laboratories need stronger control of airborne particles, room pressure, personnel entry, sample transfer, airflow stability, temperature, humidity, and cleaning management.

Before this project, the client was concerned about sample contamination, uncontrolled movement between rooms, unclear personnel entry, unstable room conditions, and poor separation between sample preparation areas and support areas. The client needed a laboratory cleanroom that could support daily testing while keeping the workflow simple, visible, and manageable.

STJh Cleanroom designed the project around real laboratory operation. The cleanroom includes testing rooms, sample preparation areas, biosafety cabinet rooms, clean corridors, gowning areas, pass box transfer points, storage areas, and environmental monitoring points. This helped the client create a cleaner laboratory workflow and reduce unnecessary contamination risk.

Client Pain Points

Sample contamination risk: Airborne particles and uncontrolled handling could affect sample preparation, testing accuracy, and laboratory reliability.
Open-bench exposure: Sensitive sample handling on ordinary benches could increase contamination risk during daily operation.
Unclear room zoning: Mixed laboratory functions could create cross-contamination between preparation, testing, storage, and support areas.
Uncontrolled personnel entry: Operators could bring particles into clean laboratory areas without proper gowning and entry control.
Unstable pressure control: Poor pressure zoning could allow contamination to move between laboratory rooms and corridors.
Weak sample transfer control: Frequent door opening and uncontrolled transfer could disturb airflow and increase exposure risk.
Limited monitoring visibility: Without real-time monitoring, abnormal pressure, temperature, or humidity changes may not be found quickly.
Poor laboratory workflow: Inefficient equipment placement and unclear movement paths could reduce daily work efficiency and make cleaning harder.

Cleanroom Solution

STJh Cleanroom provided a complete laboratory cleanroom solution based on the client’s testing process, sample flow, room function, equipment layout, and cleanliness requirements. The cleanroom was divided into clean work zones, sample preparation areas, biosafety cabinet areas, gowning areas, clean corridors, sample transfer points, and support rooms.

The cleanroom uses HEPA-filtered air supply, laminar airflow over critical work areas, pressure zoning, controlled personnel entry, pass box sample transfer, biosafety cabinet integration, temperature and humidity control, observation windows, and environmental monitoring. These systems help reduce contamination risk and support more stable laboratory operation.

Key Cleanroom Systems

1. Laboratory Workstations & Biosafety Cabinets

The laboratory includes stainless steel worktables, organized benches, biosafety cabinets, sink areas, and clean storage spaces. This helps create protected work zones for sample preparation and routine laboratory tasks.

Protected sample preparation zones
Integrated biosafety cabinets
Organized bench and equipment layout
Improved process isolation for sensitive work

2. HEPA & Laminar Airflow System

HEPA filtration and laminar airflow help maintain low-particle conditions around critical laboratory work zones. This is important for sample preparation, clean handling, sensitive testing, and contamination control.

HEPA-filtered supply air
Laminar airflow over work zones
Controlled return air design
Reduced airborne particle and sample contamination risk

3. Pressure Zoning & Room Segregation

The cleanroom uses pressure zoning to separate critical laboratory rooms from clean corridors, support areas, and material transfer zones. This helps reduce contamination migration and improves control between different laboratory functions.

Controlled pressure cascade
Separated critical rooms and support spaces
Cleaner room-to-room workflow
Reduced cross-contamination risk

4. Gowning & Personnel Entry

Personnel entry is one of the most important contamination control points in laboratory cleanrooms. The project includes gowning storage, cleanroom garments, hand hygiene station, and controlled entry sequence.

Controlled gowning sequence
Hand hygiene before laboratory entry
Cleaner operator movement
Reduced people-borne contamination

5. Pass Box & Sample Transfer

The pass box system allows samples, tools, bottles, containers, and laboratory supplies to move between zones with less exposure. It reduces unnecessary door opening and helps maintain airflow and pressure stability.

Controlled sample and tool transfer
Reduced door opening frequency
Cleaner transfer between rooms
Improved sample handling and traceability

6. Temperature & Humidity Stability

Stable temperature and humidity help protect samples, testing instruments, reagents, and laboratory procedures. The HVAC system was planned to keep room conditions more consistent during daily operation.

Balanced HVAC control
Stable room conditions for laboratory processes
Support for sample handling and instrument stability
Reduced environmental fluctuation and moisture-related issues

7. Environmental Monitoring & Alarm

The monitoring system provides real-time visibility of room pressure, temperature, humidity, and system status. This helps laboratory staff respond earlier when room conditions change.

Real-time pressure monitoring
Temperature and humidity tracking
Visible room status display
Alarm-ready response for abnormal conditions

8. Clean Workflow & Lab Layout

The laboratory layout was planned around sample preparation, testing, biosafety cabinet operation, storage, personnel movement, and cleaning access. Clear zoning helps reduce workflow conflicts and makes daily laboratory management easier.

Organized laboratory zoning
Clear personnel and sample movement
Better equipment placement
Improved daily operation and future expansion support

Project Result

After completion, the client received a 620㎡ laboratory cleanroom designed for sample preparation, routine testing, biosafety cabinet operation, sample transfer, and controlled laboratory workflow. The cleanroom provides cleaner work zones, more organized laboratory movement, better room pressure control, and real-time environmental visibility.

The final layout supports daily laboratory use while reducing contamination risk, improving sample handling discipline, and making the cleanroom easier to operate and maintain. For testing and research laboratories, this type of cleanroom is an important foundation for stable work quality and more reliable laboratory operation.
