加拿大采购需求：薄层色谱板

I'm looking to purchase aluminum-backed TLC plates for our business. Could you please provide a quote for the smallest available packaging and size? Also, I'm interested in the particle size of the silica used in these plates. Your prompt response will be appreciated as we aim to finalize our procurement soon. If you have any additional details about the product specifications or recommended uses, please include that as well. Thanks!
