马来西亚采购需求：低温容器，液氮冷冻机，不锈钢液氮容器，不锈钢液氮罐，液氮钢瓶，液氮杜瓦瓶

I'm looking to purchase a 5-liter tank, ideally just one piece to start with. Could you provide me with some details about the available options? Specifically, I'm interested in the material, design, and any customization possibilities you might offer. Additionally, please include your pricing, lead times, and any minimum order requirements. I'm keen to understand the quality standards you uphold, as well as any certifications the product may have. Once I have this info, we can discuss next steps. Thanks!
