Overview

The Vacuum Pump provides a dedicated vacuum source for Apogee® Spin Coaters and Developers when facility vacuum is unavailable or insufficient, ensuring stable substrate retention during rotation.

Key Capabilities

Key performance characteristics include:

• Oil-free diaphragm design eliminates contamination risks associated with oil-based vacuum systems

• Chemically resistant PTFE-coated internal components provide a PTFE-coated diaphragm and pump head; suitability should be checked for the specific process conditions

• Cleanroom-compatible operation suitable for semiconductor research, university laboratories, and advanced materials processing

• Quiet operation (~50 dB) minimizes disruption in laboratory environments

• Compact footprint allows convenient placement near the equipment or within workstation enclosures

The pump delivers sufficient vacuum and flow capacity to maintain secure substrate retention during typical spin coating operations, including high-speed acceleration and extended spin cycles.

Because the vacuum source is dedicated to the equipment, performance remains consistent regardless of other vacuum users within the facility.

Safety & Facilities

The oil-free design eliminates the need for vacuum oil maintenance and reduces the risk of chemical contamination in cleanroom environments. Integrated thermal protection safeguards the pump against overheating, automatically pausing operation if internal temperatures exceed safe limits and resuming once cooled.

Maintain at least 3 in (76 mm) of clearance on all sides of the pump for adequate ventilation and cooling. Place the pump in a well-ventilated area; do not enclose it in a sealed cabinet or obstruct ventilation openings.
