PTL-VM2 Vacuum Programmable Dip Coater with Touch Screen Controller
The PTL-VM2 is engineered for laboratory applications requiring uniform thin film deposition on small substrates under controlled vacuum environments. It accommodates samples up to 1 inch diameter and 3 inches length, which are dipped into coating solutions contained within a vacuum-sealed quartz tube. This setup minimizes contamination and evaporation, ensuring high-quality coatings.
The device integrates two DC motors within a rigid aluminum frame to provide precise vertical dipping and sample rotation. The dipping and pulling speeds are programmable from 1 to 200 mm/min with an accuracy of ±0.05%, controlled via a user-friendly color touch screen interface. The vacuum chamber consists of a 50 mm outer diameter quartz tube sealed with a stainless steel flange, allowing vacuum levels down to 10⁻⁵ torr with a turbopump.

Typische Anwendungsbereiche
Ideal for research and development of thin film coatings on small substrates, especially where vacuum conditions improve film quality and reduce contamination. Suitable for coatings involving nanoparticles, polymers, or other solution-based materials requiring controlled dipping and rotation.
Can be integrated with plasma cleaners for substrate surface treatment and ultrasonic processors for solution homogenization to enhance coating uniformity.
Hinweise zur Konfiguration und zum Betrieb
The quartz tube can be inserted into a temperature-controlled furnace for high-temperature dip coating up to 1000°C (optional). Vacuum pumps are sold separately to achieve desired vacuum levels. Customized sample holders are available upon request to accommodate different substrate sizes or shapes.
Users should ensure proper vacuum sealing and monitor vacuum levels during operation. Plasma cleaning and ultrasonic dispersion of coating solutions are recommended preparatory steps for optimal film quality.
