Large Desk Turbo-Pumped Carbon Coater – DCT-300

DCT-300 | Large Turbo Pumped Carbon Coater | New DCT Model | Desk Carbon Coater

DCT-300 is a turbo-pumped carbon coater with large chamber that is ideal for sample preparation for FE-SEM, EDS/WDS, TEM, EBSD analysis, and thin film applications. This high-vacuum coater offers high quality uniform carbon films with fine grain sizes which are suitable for specimens that require high-resolution and high-quality characterization.

DCT-300 with a 300 mm Dia. cylindrical chamber allows long-term deposition on samples with a diameter of up to 15 cm or several small specimens. The full-automatic programmable carbon coating process allows easy, precise, and repeatable performance. 

Carbon fibers (Thread) or rods can be installed on separate chamber heads, as ordered by the customer, to coat the samples through different flash, pulsed or ramped modes (Last mode available for carbon rod) in a manual or automatic deposition process.

    • Automatic carbon fiber/rod deposition according to the set thickness value
    • Records and plots coating parameters graphs
    • Storing coating recipes for repeatable depositions

Pulsed Carbon Fiber Evaporation

The desk vacuum carbon coater is able to perform pulsed carbon fiber evaporation. Short pulses provide more controlled deposition and significantly reduces the number of debris associated with traditional carbon deposition.

Carbon Rod Evaporation (Optional)

The desk high vacuum carbon coater, DCT-300, could be equipped with carbon rod head (Optional). For this case an external 0-100 A high current power supply should be used instead of the internal high current power supply which is designed for carbon fiber evaporation.

Clean Vacuum

The vacuum chamber is Cylindrical Pyrex. The DCT-300 is fitted with an internally mounted 90 L/s turbo molecular pump, backed by a 6 m3/h two-stage rotary vane pump (Optional). It introduces clean vacuum without oil contamination which normally exists with ordinary diffusion pump.

DCT-300 Touch Screen Control

DCT-300 is equipped with a 7” colored touch screen with full automatic control utilizing a user-friendly software to control and adjust the deposition process data. The vacuum and coating sequence information can be monitored as digital data or curves on the touch screen. The last 300 coatings information is saved on the history page and can be transferred to PC by a USB port on the device.

Sample Holder Stages of DCT-300

The DCT-300 can be equipped with different sample stage configurations depending on the user requirements. The sample stages are rotatable with adjustable height and angle and easy to change. The rotary planetary sample stage is a good choice for uniform coating of porous specimens (Optional).

For deposition on large samples, a 6-inch rotatable (No incline adjustable) sample holder stage is recommended (Optional).
