PP3006 Freeze Transport Preparation System

PP3006apply toSEM、FIB/SEMFreezing transfer system with vacuum platform

PP3006 CoolLokThe system isSEM，FIB / SEMOr other vacuum systems provide fast transmission and low-temperature sample observation functions. Its applications include samples sensitive to electron beams and materials that require low-temperature observation, such as plastics, polymers, and other materialsKDielectric and soft hard mixtures provide thermal protection. This system can also be used for sample transfer of ambient temperature samples from glove boxes under inert gas protection.

Instrument features:

•Quick sample exchange

•The temperature can be lowered to-190℃The stability is better than±0.5℃

•Split cooling system, can run for a whole day after being filled with liquid nitrogen

•Two independent gas channels are used to cool the cold stage and cold trap respectively

•Sample transfer under vacuum and inert gas protection

•Optional rapid sample pre cooling device

QuickLokIncluding a loading chamber with embedded control for vacuum pumping, de vacuuming, and sample transfer, the chamber is installed on a suitable vacuum chamber port. This system also includes customized vacuum chamber interface flanges, connectors, and adapter parts connected to vacuum components (see below)“vacuum pumping”）. The interface is equipped with a subcooled nitrogen gas pipeline feeding through the electron microscope cold stage and cold trap.

CoolLokThe standard sample cooling method is achieved through the contact between the transferred sample and the electron microscope cooling stage, so the freezing speed is relatively slow. This applies to hard, non-aqueous samples, but for liquid based materials, rapid pre cooling is necessary, and then transferred to the cold stage through vacuum, which can reduce the damage of ice crystal growth to the sample. For such applications, it is necessary to24425Options for liquid nitrogen mud pre cooling workstation.

Load the sample onto the appropriate sample holder (sample shuttle), and then install the transfer device onto the airlock. After the non vacuum space is evacuated to a preset vacuum value, the gate valve opens and the sample is transferred to the electron microscope sample stage. For sample transfer from other vacuum systems or glove boxes, please request the corresponding interface flange information available. If a liquid nitrogen mud pre cooling workstation is selected, sample transfer under vacuum can be obtained through this workstation.

For applications that do not require frequent sample changes, it is only recommended to usePP3005Search for the ability to transfer room temperature samples toSEM, FIB/SEMFor samples in other suitable vacuum systems, please refer to:PP3004QuickLokFor many applications(Especially in the field of life sciences)Speaking of which, cold cracking and sputtering coating are essential process steps that require the purchase of advanced technologyPP3010 –Complete low-temperature scanning electron microscopy preparation system.
