土耳其采购需求：350克气象气球，气象气球，近太空研究，气象气球，气象气球制造商，气象气球供应商

We are a university research center in Turkey, currently engaged in meteorological studies using weather balloons. Our inventory is running low, and we'd like to gather pricing info for different types of balloons you offer. We have a strong preference for specific weights, but we're also interested in seeing prices for other options in your product line. Your prompt response would be greatly appreciated as it will help us make our purchasing decisions quickly. Thank you!
