The Q Plus Series is the latest version of Quorum's internationally acclaimed, market-leading range of sputter and carbon coaters. They are increasingly used in high-resolution microscopy, where ultra-fine coating is a must.
Sputter coating is the standard method for preparing non-conducting or poorly conducting specimens prior to observation in a scanning electron microscope (SEM). Quorum offer low-cost, rotary-pumped sputter coaters for depositing non-oxidising metals - such as gold (Au) and platinum (Pt) - and turbomolecular-pumped coaters, suitable for both oxidising and non-oxidising metals, such as chromium (Cr).
To offer improved ultra-fine coating Quorum have introduced the NEW Q150V Plus, which offers an ultimate vacuum of 1 x 10-6mbar for superior results.
Large chamber sputter coaters are available for specimens up to 200 mm in diameter. Most Quorum coaters can also be configured for carbon evaporation using easy-change carbon rod and carbon fibre inserts.
The Q150V Plus is suitable for high-vacuum applications. This new product offers users the capability to produce finer grain size and thinner coating for ultra-high-resolution applications (above x 200k magnification).
The Q150T Plus coater is suitable for SEM, TEM and many thin film applications. It is available in three formats: as a sputter coater, carbon coater or both sputtering and carbon evaporation in a single compact system.
The rotary-pumped Q150R Plus coater is suitable for W-SEM sputtering applications using non-oxidising metals and for carbon coating SEM specimens for EDS and WDS.
For larger specimens, the Q300T T Plus (turbomolecular-pumped) models allow coating of a single large diameter specimen up to 8"/200 mm (e.g. a wafer), or multiple smaller specimens over a similar diameter. Both have triple sputtering heads to ensure even coating deposition.
For thin film applications the Q300T D Plus Dual Target Sequential Sputter Coater allows consecutive metal layers to be sputtered without the need to break vacuum.
The Q150 GB is a modular version of the Q150T ES coater designed to be integrated into a glove box.
Completing the range is the SC7620, a compact, entry-level SEM sputter coater which is available with an optional carbon fibre evaporation attachment.
