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.
Key Features
- Vacuumless sample holding via grooved 4″ PTFE spin plate designed for 50×50 mm samples.
- Spin speed adjustable from 500 to 8000 RPM with programmable timing from 1 to 60 seconds.
- 24 VDC motor with heavy-duty aluminum case for stable and reliable operation.
- Argon gas compatibility for use inside glove boxes and inert atmosphere environments.
- Includes 20 mL syringe with adjustable and rotatable support arm for precise liquid dispensing.
- Comes with seven 0.3 mm thick nylon plates and removable double-sided tape for versatile sample mounting.
- Digital control panel with two programmable segments for flexible coating protocols.

Typical Applications
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.
Configuration & Operating Notes
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.
