CRYO-SEM & CRYO-FIB/SEM PREPARATION EDITION II zzzPP3010 Cryo-SEM/Cryo-FIB/SEM Preparation System (continued)


OPTIONS AND ACCESSORIES Rapid Warming Tower for the CHE3010


Gas-cooled SEM cold trap (temperatures down to -190°C). Tailor-made to suit each SEM


systems. The SEM cold stage has a temperature range of down to -190°C and a temperature stability of < 0.5°C.


Compatibility with SEM Stage Bias Mode The PP3010 cold stage is fully compatible with SEM stage bias/beam deceleration modes of up to 5kV.


CHE3010 Off-Column Cooling The CHE3010 is a fully integrated, remotely mounted cooling system which comes as standard with every PP3010. The CHE3010 is used to cool the SEM stage, SEM cold trap and cryo preparation chamber cold stage and cold traps and will typically reach temperatures down to -90°C or lower.


The CHE3010 is remotely positioned (typically on the floor behind the microscope) and at normal operating temperatures can run for up to 24 hours between fills. This greatly simplifies the cryo process (no more checking on dewar status and topping off), but also allows overnight, unattended operation – particularly useful for some automated FIB/SEM "slice and view" protocols.


Single Port Interface to the SEM or FIB/SEM Where SEM geometry allows, both the cryo preparation chamber and the SEM cooling system can be fitted to a single chamber port (the minimum port diameter is 38 mm). This gives a tidy installation and frees up a valuable chamber port.


Rotary Cold Stage for continuous 360 degree rotation below -165˚C


This device is meant to facilitate a rapid warming of the CHE3010 (Cryo-Heat Exchanger) associated with the PP3010 Cryo-SEM preparation system. The Rapid Warming Tower in conjunction with a 1 liter/min Nitrogen gas flow rate dramatically reduces the lag time before the SEM or Prep chamber components return to room temperature so venting can occur. A process that normally takes hours can be completed in minutes, allowing maintenance or reconfiguring the SEM back to room temperature operation. Accepts many common, locally obtained hair dryers. (Hair Dryer not included).


Specimen shuttles and stubs


The PP3010 is supplied with a selection of holders, and a range of additional specimen shuttles and stubs is also available. (See Ordering Information for details).


Carbon Evaporation and Film Thickness Monitor A carbon evaporation attachment and a terminating film thickness monitor can be fitted. Both are fully integrated (no external control boxes required).


Pressurized LN2 Dewar


The PP7450/60L is a highly recommended option that generates dry nitrogen gas used for cooling the SEM cold stage & cold trap and cryo preparation chamber and cold shields. In addition, LN2 can be decanted for slushing (freezing). During normal operation the PP7450/60L will generate dry nitrogen gas for up to eight days usage.


If the PP7450/60L is not included, appropriate, locally sourced, nitrogen gas cylinders can be used. It is important to ensure that it has low moisture content – if in doubt, please contact us.


Cryoflow Work Options Glove Box Valve/Airlock Interface


The airlock is connected to a glove box using a generic NW fitting and for most applications requires a suitable pumping system (rotary pump or turbomolecular plus diaphragm pumping system).


The airlock is designed to accept the PP3010 vacuum transfer device.


For full details of this and other accessories please see Ordering Information.


TEM Prep Slusher Option


Offers an easy, convenient way of transporting pre-frozen specimens to and from the PP3010.


• Conveniently locates into the Prepdek® workstation of the PP3010


• Freely transportable, e.g. between high pressure freezer, cryoultramicrotome and the PP3010


• Ideal for loading/unloading TEM grids and grid holders


• Tilting holder for cryo shuttles (holders). Allows the easy transfer of specimens from external freezers (e.g. high pressure, jet, slam etc)


• Option for PP3010 and previous PP3000T and PP2000/PP2000T models


Pre-Frozen Sample Loading Jig for PP3010


This loading jig allows you to comfortably load pre-frozen samples, ie: HPF or Rivets, into the PP3010 specimen shuttles (not included). The loaded shuttles can then be transferred to the PP3010 slushing pot on the Prepdek®


. Includes the LN2 container, Lexan cover, loading jig, and a short transfer rod. Pre-Frozen Sample Loading Jig
