介绍：
适用于使用氯消du的水体采样，如EPA核准可用于饮用水采样。采样袋中有硫代硫酸钠药片，可以在采样的同时中和余氯对样品分析的影响。 底部采用折叠结构，装入液体样品后可以直接站立。带有标识区，方便记录各项采样信息。
密封性极好，能折叠三次。至高使用温度达82℃，可以在任何低温下使用，甚至液氮环境。所有产品都经过严格的mie菌处理，请放心使用。
When it is necessary to run multiple tests, this 18-oz. Thio-Bag® provides a 300 ml sample. It contains three times the amount of sodium thiosulfate as the smaller Thio-Bag® and holds 300 ml when filled to the top of the white write-on strip (fill line).
Capacity is measured in fluid ounces when the bag is closed and tab is folded over three times. Volume and dimensions are approximate; bags should not be used at temperatures above 180℉(82℃). Bags can be frozen to any temperature, even liquid nitrogen - careful handling required after freezing. All bags are sterilized after manufacturing.
