Contains filter layer.69 oz. （2,041 ml） capacity7-1/2" W x 15" L （19 x 38 cm）4.0 mil （.102 mm） thickBox of 250 均質(zhì)過濾袋；容積：69oz/2,041ml；尺寸：19x38cm；膜厚：0.102mm；包裝：250個(gè)/盒；品牌：美國NASCO
三層結(jié)構(gòu)，中間一層濾網(wǎng)（孔徑0.33mm），樣品放入過濾網(wǎng)一側(cè)，均質(zhì)后從另一側(cè)取樣，避免固體物質(zhì)對分析造成影響，同時(shí)也更方便使用移液管取樣。
適合于液體樣品采樣，密封性*，能折疊三次。zui高使用溫度達(dá)82°C ，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)格的滅菌處理，請放心使用。
These special bags contain a third layer of finely perforated polyethylene, which filters out the solids in the sample when used in a homogenizer blender. Bags feature a filter layer of finely perforated polyethylene, to separate the liquid and solids, allowing for easy pipetting of the sample. The hole diameter in the filter layer measures .013 inches （.33 mm）, 330 microns, and there are 1,840 holes per square inch, 285 per square cm. The filter is sealed into the perimeter of the bag on the sides and bottom, allowing the sample to be placed in the bag on either side. The liquid will transfer through the filter, but the solids stay on one side.
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.
