I have prepared the samples but haven't got the chance to image on Krios yet. I actually had quite a lot of experience working with these grids before when I was in China. It did work much better than carbon film grids for a few of my previous samples. Therefore I want to give it a try for my current sample.

​

I remember the price for such a regular grid was bout 60RMB about 1 year ago. But a previous colleague in China just told me that the price has risen to 84RMB recently. The price you offered is bit more expensive than that, but not a lot.

If you can keep certain amount of products in stock, it would be more convenient for us to order. I know R1.2/1/3 type is more popular for single particle people, but there would be more people working on tomography in which case the R2/2 type would be preferred. Our lab, as well as others in our department, may also need more in the future. Hope it will be easier to order. Personally, I am expecting to receive the product in 2-3 weeks.
