Types of Cleanroom Tables You Should Know About
A cleanroom is a room where people work on products manufactured according to an industrial standard’s requirements. However, cleanrooms have also been useful for manufacturing pharmaceuticals, computer chips, and semiconductors. Cleanrooms have certain stringent criteria, including temperature control, access control; monitoring systems; and air filtration methods. In addition, a pressure differential is maintained between the outside of the building, where no contaminant can enter with the inside of the building, where chemical reactions occur.
Stainless Steel Cleanroom Tables:
Cleanrooms are often equipped with stainless steel tables, which are not prone to rust. Laboratory Cleanroom seating by Cleanroom Tables is used for various purposes and includes laboratory and office desks. Laboratory desks in cleanrooms are made of stainless steel as this material is usually resistant to corrosion and can be cleaned easily. In addition, the surface of the workstations in laboratories must be easily disinfected.
Stainless steel tables do not rust or decay over time, unlike wooden or plastic ones. Stainless steel can also be used as a work surface in cleanrooms so that microscopes and other instruments can be moved around on the surface without affecting their positions, unlike table tops which stick to the table or slide on top of it.
Electropolished Cleanroom Tables:
It is a low-cost alternative to polished stainless steel laboratory tables with the same functionalities. Electropolished stainless steel tables are made from processed steel used in construction. It is then electroplated using either a chemical or an electroplating process. The electroplating process requires functioning electrical and chemical circuits and electrodes, while the chemical process requires an electrolytic solution. When a solution containing chromium is passed through the electrodes and current is passed through it, a thin layer of chromium forms on the surface of the metal.
Electropolished stainless steel tables are relatively inexpensive compared to polished stainless steel tables. The surfaces of the boards are rough and have a matte finish, making them easy to clean. In addition, electropolished stainless steel boards have chemical resistance, allowing them to be used in chemical laboratories.
Perforated Cleanroom Tables:
The other alternative available to cleanroom manufacturers is the perforated cleanroom table. This type consists of metal or plastic perforations that provide extra space for equipment and drawers. The tables may also have built-in lockable furniture to secure equipment.
Most of the perforations do not need to be waterproofed as this kind of table is usually installed under a cover, so they remain fairly dry. In addition, the tables are lightweight and easy to handle, which makes them portable.
Controlled Environment Tables:
Controlled environment tables are used in laboratories to ensure that their surfaces remain clean and sterile. There are different types of controlled environment tables available that have different features. They are mainly categorized into four groups:
- Floor-mounted laboratory tables with rolling carts or trays.
- Countertop laboratory desks with drawers.
- Workstation-mounted laboratory desks with drawers and trays on the top surfaces.
- Laboratory table tops with integrated drawer systems and countertops for lab benches or workstations.
Controlled environment tables have small rolling systems that may be wheels, casters, etc., which allows them to go easy on floors. Different shape/size controlled environment tables are required in various laboratories depending on their purposes.
People in cleanrooms can use ESD workstations as they are designed to prevent electrostatic discharge. The ESD workstations are mounted on the table’s surface and contain a grounded mat that limits electrical charges.
These tables have a top layer of non-conductive materials, such as anti-static plastics, wood laminate, ceramic tiles, or glass. In addition, they have grounding cords that may include extension cords or cables with insulated connectors, which are often attached to grounded electrical outlets.
ESD workstations are sturdy and have a rugged build quality. They are easy to clean and disinfect. Their surface is non-conductive, preventing workers, equipment, and objects’ electrostatic charging while in use. In addition, they have an anti-static property that limits static charges on the surfaces of the tables and causes damage to electronic devices.
Explosion-proof cabinets are usually used in cleanrooms where hazardous chemicals or biological organisms can be stored by scientists safely. The doors of these cabinets must allow for ease of access and withstand high-pressure situations like explosions or fire. In addition, the cleanroom cabinets must have a high level of protection to prevent the escape of harmful chemicals. There are different types of explosion-proof cabinets available, including explosion-proof glass wall cabinets, explosion-proof metal cabinets, explosion-proof smoke cabinets, and explosion-proof safe cabinets.
They are rust-resistant. People in these cabinets can use materials like glass, acrylic, and porcelain. The metal parts of the cleanroom cabinet are usually made from steel and aluminum, while the glass in these cabinets is often made from either tempered or heat-resistant glass. The seals on the doors of these cabinets are flexible to prevent the escape of any hazardous air or toxic chemicals.
