Product Description
Ideal for SEM sputtering and carbon coating applications
The Q150R is available in three formats: sputtering, carbon evaporation or both. Depending upon the selected configuration, the Q150R can be a sputter coater for scanning electron microscopy (SEM), a carbon coater suitable for SEM (eg EDS and WDS), or both - in a single easy-to-use system.Moulded case with colour touch screen
The Q150R is presented in a custom moulded, one-piece case - allowing easy servicing access. The colour touch screen allows multiple users to input and store coating ‘recipes’. The case houses all the working components, with an automatic bleed control that ensures optimum vacuum conditions during sputtering.The vacuum chamber has an internal diameter of 165mm/6” and comes with an integral implosion guard. The Q150R also includes ‘vacuum shutdown’, which enhances vacuum performance by allowing the chamber vacuum to be maintained when the system is not in use.
A variable speed rotary specimen stage is fitted as standard, with other stages available as options - see Options and Accessories.
Sputter coating, carbon coating or both
The Q150R is available in three formats, each with a range of optional accessories:* Q150R S - a compact rotary-pumped sputter coater for non-oxidising (noble) metals. A gold (Au) target is fitted as standard, with others - such as gold/palladium (Au/Pd) and platinum (Pt) - available as options.
* Q150R E - a compact rotary-pumped carbon fibre coater, ideal for SEM EDS and WDS applications. Fitted with a carbon fibre head insert; an optional carbon rod insert is also available.
* Q150R ES - a combined system with both sputtering and carbon coating. The deposition inserts can be swapped in seconds and the intelligent system logic automatically recognises which insert is in place and displays the appropriate operating settings.
Each of the above can be fitted with a range of optional accessories (a carbon rod coating insert, film thickness monitor, glow discharge etc). See Options and Accessories for details.
Rapid data entry
At the operational heart of the Q150R is a simple colour touch screen, which allows even the most inexperienced or occasional operator to rapidly enter and store their own process data. To further aid ease of use, a number of typical sputtering and carbon coating profiles are already stored.Maintenance
The intuitive touch screen interface features maintenance prompts which highlight:* Time of last clean
* Coating time since last cleaned
* System ‘on time’
* Time of last service.
Additional Information
| Glow Discharge Attachment | The primary application of glow discharge is as a technique for the surface modification, or ‘wetting’, of newly-evaporated transmission electron microscopy (TEM) carbon support films.
HydrophilisationFreshly-made TEM carbon support films tend to have hydrophobic surfaces which inhibits the spreading of suspensions of particles in negative staining solutions. However, after glow discharge treatment with air, the carbon film is made hydrophilic and negatively charged, thus allowing easy spreading of aqueous suspensions. With subsequent magnesium acetate treatment the surface is made hydrophilic and positively charged.In addition to glow discharge treatment using air, other process gases may be used to modify surface properties. For example, methanol as a process gas results in the surface becoming hydrophobic and negatively charged. Such treatment can facilitate the optional absorption of selected biomolecules |

| Options and Accessories (including details of coating head inserts and specimen stages that are fitted as standard) | Coating head optionsA range of interchangeable, plug-in style coating head inserts are available:* Sputtering head insert - suitable for non-oxidising (noble) metals. Supplied with a 57mm Ø x 0.1mm thick gold (Au) target as standard (R S and R ES versions). For additional targets see Ordering Information * Additional sputter head inserts - available for quick coating material change (R S and R ES versions) * Carbon fibre evaporation head insert - fitted as standard to R E and R ES versions * Carbon rod evaporation head insert - for 3.05mm Ø rods (available as an option for R E and R ES versions). Specimen stagesThe Q150R has specimen stages to meet most requirements. All are easy-change, drop-in style (no screws) and are height adjustable (except rotary planetary stage):* Rotation stage - 50mm Ø (supplied as standard). This stage only rotates - no tilt or height adjustment * Rotate-tilt stage - 50mm Ø with height adjustment (target to stage height variable between 37-60mm). Tilt angle can be pre-set (up to 90°) * Variable angle ‘Rotacota’ rotary planetary stage - with 50mm Ø specimen platform * Flat rotation stage for 4"/100mm wafers * Rotation stage for glass microscope slides. Other options* Extended height chamber - for tall specimens* Film thickness monitor (FTM) - the optional FTM attachment (10454) consists of a controller and quartz crystal oscillator built into the Q150R and a vacuum feed-through, chamber-mounted crystal holder and quartz crystal. As sputtered or evaporated material is deposited onto the crystal, so its frequency of oscillation is modified. This ‘modification’ is used to measure and control the thickness of material deposited. |
