Q：Can we store more than 4 holders? A：Up to 8 bottles can be stored in total with the EX4 additional station (optional).
Q：If EX4 additional station is added, is the vacuum level linked? A：Linked.
Q：What is the role of the lights? A：To remove dirt from the tip and holder.
Q：Are there any standards (types) of holders that can be used? A：Compatible with JEOL, FEI, and HITACHI TEM holders.
Q：What is the make and model of the pump incorporated in the LF4? A：The pump manufacturer is Pfeiffer Vacuum. The LF4 incorporates the following two types of pumps ・Diaphragm pump: MVP 015-2 DC ・Turbo molecular pump: HiPace 80
Q：What are the conditions during an emergency? And if so, how do I re-commissio n the system? A：In the event of a power failure or other emergency, the diaphragm pump and tur bo pump will automatically stop, but the inside of the chamber will not be opene d to the atmosphere.When power is restored, turn the main power OFF and then ON again, and start operation according to the normal procedure.
Q：Regarding LF-4+EX-4, is the holder leak-tested all at once, or can it be leak-test ed individually? A：All ports are designed for simultaneous leak testing. It is not possible to take out and test holders individually.
Q：Is it acceptable to measure the temperature without keeping the system under v acuum? Will there be a difference between vacuum and atmospheric condition s? A：A difference in temperature is expected, so measurements should be performed under vacuum. In the atmosphere, heat escapes through the air, which can resu lt in temperature readings that differ from those obtained under the actual oper ating condition (vacuum).
Q：Could you provide the main specifications of the LF4 and the compatible holder s? A：The LF4 cleans both the sample and the entire holder surface under high vacuu m without causing sputtering damage. This process improves the quality of TEM and STEM data. ・Main unit size and weight: W366 × D435 × H400 mm / 30 kg ・Power supply: AC 100 V, 5 A (a step-down transformer is required for 200 V us e) ・Vacuum performance: ≤ 1×10⁻⁴ Pa (with dummy plug, at 20°C, without light ba king) ・Illumination annealing temperature: Room temperature to max. 150°C, recom mended range 80–130°C ・Compatible holders: TFS and JEOL TEM holders ・Operating environment: Application laboratory, room temperature 15–30°C (n o condensation)
