加拿大采购需求：小型冷冻干燥机、真空冷冻干燥机、玻璃夹套反应釜、旋转蒸发仪、刮膜萃取、分子蒸馏

I'm looking to purchase a freeze dryer machine, ideally with all necessary accessories included. Alongside that, I would like to have a small motor to go with it as well. I'm interested in a model that can accommodate around 3 to 5 trays, and I'm hoping to find an affordable option since it's mainly for my family of seven. Let me know what you have available!
