RotaQ ES Combined Sputter & Carbon Coater
The RotaQ ES from Quorum Technologies is a cutting-edge combined sputter and carbon coater engineered for automated, high-quality sample preparation for Scanning Electron Microscopy (SEM). This versatile rotary pumped sputter coater utilizes an intelligent swappable head system, enabling instantaneous tool-free transitions between noble metal sputtering (Au, Pt, Pd) and carbon fibre evaporation.
Designed specifically for Tungsten and LaB6 SEMs as well as Benchtop SEMs, the RotaQ ES comes standard with a 50mm tilting stage for uniform coating of complex 3D structures and a high-precision Film Thickness Monitor (FTM) to ensure reproducible results. With its advanced touch screen interface and Glow Discharge option, it is the ultimate solution for multi-disciplinary labs requiring both metal and carbon coating capabilities.

RotaQ ES Frequently Asked Questions
As authorized Quorum sputter coater suppliers, we offer competitive pricing in INR. Please click "Get Quote" for a formal quotation including installation.
The RotaQ ES requires a rotary pump (e.g., Pfeiffer Duo 6 or Edwards nXDS6i). We supply the system as a complete turnkey package with the correct pump and oil mist filter.
Yes, the RotaQ ES deposition head inserts can be swapped to allow for Metal evaporation and Glow Discharge. This is excellent for cleaning SEM stubs or modifying surface wettability on TEM grids.
The system is designed for high throughput. Pump down to operational vacuum (1x10-1 mbar) takes just a few minutes, and typical sputtering runs are 60-120 seconds.
A Gold (Au) target is supplied as standard. Options include Gold/Palladium (Au/Pd), Platinum (Pt), Silver (Ag), and Platinum/Palladium (Pt/Pd). Carbon fiber or rods are used for evaporation.
Yes, the evaporation head supports 3.2mm carbon rods or carbon fibre, with evaporation currents from 5-75A dependent on the process.
