The EMS 7620 is a compact, low cost SEM sputter coater. When combined with the optional carbon attachment EMS 7620-CF it makes the ideal low-cost SEM sputtering and carbon coating system package. The EMS 7620 is fitted as standard with a glow discharge function, making it ideal for the hydrophilisation, or ’wetting’, of carbon-coated TEM grids and other surface modifications. The EMS 7620 is robust, easy to operate and is backed up with a three-year warranty.Features
The EMS 7620 is primarily designed for use with tungsten film SEMs. For extra fine grain coating required for most FE-SEM applications, high vacuum coating is required - see the EMS 150T, or for larger specimens see the EMS 300T T.
- Low cost
- Simple operation
- Magnetic deflection sputter coating head
- Compact design
- Carbon fiber evaporation option
- Adjustable height specimen stage
- Easy to change sputter targets - gold/palladium (Au/Pd) standard
- Built to all the latest safety standards - features include positive break electromechanical interlock which ensures the sputter coating head is electrically isolated when the optional carbon attachment is in use
- Robust and reliable
- Three-year warranty
The EMS 7620 is ideally suited to the budget-conscious user who none-theless demands quality results from an easy-to-use instrument. Designed for routine applications, the EMS 7620 uses a basic magnetron sputter head with a simple-to-replace disc target (gold/palladium (Au/Pd) as standard). The head is hinged for easy operation and fitted with electrical safety interlocks.
To prevent accidental damage the high voltage lead is shielded. The plasma current is variable by adjustment of the vacuum level using an argon leak valve with the plasma voltage pre-set. For maximum sputter coating efficiency the gas injector system ensures that argon gas enters the chamber close to the plasma discharge. Venting is to argon.Fast cycle times
The 100 mm/4" diameter Pyrex cylinder is mounted on an aluminium collar and sealed with O rings. The small vacuum chamber means pump-down times and cycle times are fast; it also allows a small economical rotary pump to be used.
The specimen stage is height-adjustable over a wide range and can easily be removed to accommodate larger specimens. The system is controlled manually by a 180-second timer with 15-second resolution. Pressure and plasma current are monitored by analogue meters.
