印度采购需求：亥姆霍兹线圈、磁场、液体热汽化、热导率、光学实验、晶体磁电机

I'm looking to place an order for 10 units of a specific type of tube. The specifications I'm interested in include a scan time of 40 ms, with a recommended filament voltage of 7.2 V. Additionally, the acceleration voltage should be set at 68 V, and a reverse bias of 8.9 V is required. It's also important that the grid voltage is at 6.2 V, which is recommended. Please provide me with pricing, lead times, and any available options that meet these requirements. I'm looking forward to your prompt response, as I hope to proceed with the order soon.
