加拿大采购需求：99.99 镱金属，购买镱金属，CAS 编号：7440-64-4，化学元素 yb，化学 yb，元素镱

I hope this message finds you well. I am a graduate student at the University of Toronto, and my research group is currently looking for small chunks of Ytterbium. We specifically need pieces that can fit into a tube with an approximate diameter of 10 mm. Our requirement is around 10 to 20 grams, and we are interested in understanding the pricing structure for this quantity. Could you please provide the cost per gram for the Yb chunks? Additionally, if you could share information regarding the availability and lead time for shipment, that would be greatly appreciated. Looking forward to your prompt response so we can proceed efficiently with our project. Thank you!
