介紹：

適用于使用氯消du的水體采樣，如EPA核準(zhǔn)可用于飲用水采樣。采樣袋中有硫代硫酸鈉藥片，可以在采樣的同時中和余氯對樣品分析的影響。 底部采用折疊結(jié)構(gòu)，裝入液體樣品后可以直接站立。帶有標(biāo)識區(qū)，方便記錄各項采樣信息。 

密封性極好，能折疊三次。至高使用溫度達(dá)82℃，可以在任何低溫下使用，甚至液氮環(huán)境。所有產(chǎn)品都經(jīng)過嚴(yán)格的mie菌處理，請放心使用。

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.
