底部采用折疊結(jié)構(gòu)，裝入液體樣品后可以直接站立。帶有標識區(qū)，方便記錄各項采樣信息。適合于液體樣品采樣，密封性極好，能折疊三次。至高使用溫度達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)過嚴格的mie菌處理，請放心使用。 The Whirl-Pak® Stand-Up Bag makes sample handling and testing much easier because it gives users the ability to perform important laboratory functions with both hands, because the bag will stand completely by itself. No rack or other holder is needed to keep the bag upright. When the sample is placed inside, the special gusseted bottom flattens out, allowing the bag to stand up on its own. It works just like a beaker or bottle, however, it costs less, is sterilized, won’t break, and uses only a fraction of storage space as the other containers. The white, write-on strip makes sample identification easier and more convenient. It’s easy to write on this white strip using an ordinary ballpoint pen, pencil, or felt-tip marker. The paper-like finish virtually eliminates ink smearing, and provides a surface that will accept a variety of writing instruments.
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° F (82° C). Bags can be frozen to any temperature, even liquid nitrogen - careful handling required after freezing. All bags are sterilized after manufacturing.
