VTC-50A Desktop Vacuumless Spin Coater for 4″ Wafers with Ar Gas Compatibility and Up to 8000 RPM
The VTC-50A is engineered to facilitate uniform thin film coatings on substrates up to 4 inches in diameter, particularly suited for sol-gel applications. Its vacuumless design employs grooved spinning templates to securely hold samples during high-speed rotation, eliminating the need for vacuum chucks and reducing operational costs and maintenance complexity.
This compact spin coater operates with a 24 VDC motor housed in a heavy-duty aluminum casting case, ensuring stable spinning performance. The unit is compatible with argon gas environments, allowing integration inside glove boxes for inert atmosphere processing. Spin speed and duration are digitally controlled with two programmable segments, enabling precise process customization.

Typische Anwendungsbereiche
The VTC-50A is well suited for laboratory-scale thin film deposition on semiconductor wafers, glass substrates, and other flat materials requiring uniform sol-gel or liquid coatings. Its vacuumless design and inert gas compatibility make it ideal for research environments where sample integrity and contamination control are critical.
Hinweise zur Konfiguration und zum Betrieb
The standard package includes the spin coater unit, two 4″ diameter spindle plates (one pre-installed), a plastic safety cover, a 20 mL syringe with support arm, a drain hose for wastewater disposal, removable double-sided tape, and a set of tools for sample preparation. Users can customize the groove on the spin plate or order specialized grooved plates to accommodate various sample shapes.
To enhance coating quality, substrate surface treatment with a plasma cleaner prior to spin coating is recommended. The unit should be operated with care to avoid liquid overflow into the motor area; cleaning instructions should be followed to maintain device longevity.
