10 Pack 100ml Threaded Cover SC490 Digestion Tube | Plastic Transparent Centrifuge Tube with Scale | Test Tube Free-Standing with Screw Cap | Graduated volumetric Flask

Graphite digestion/sample preparation Disposable threaded cover digestion tube Reliable measurement results - the scale makes the fixed capacity more accurate. -All scales have passed the accuracy certification, and the accuracy error is within 0.5%. - Low metal background value certification. -The tube wall has a scale line, which can dilute, digest and store water samples in the digestion tube at the same time. -You can choose 15, 50, 100 and 250mL digestion tubes of different volumes . Our digestion tube is made of transparent polypropylene homopolymer.So it can provide a higher digestion temperature (zui) than the commonly used copolymer polypropylene.130C high) and better corrosion resistance. Our digestion tube has been certified to be suitable for 68 elements - common elements on the market. Accurate molding scale allows analysts to easily accurate the volume to less than 0.5%. Each scale line is certified in batches. Each scale line is certified by capacity, so that the digestion tube can be used as either a measuring cylinder or a storage container. After digestion, the sample convering well can be covered for storage, thus eliminating time-consuming pipetting steps and possible sample pollution. Such a "one-tube" system greatly reduces the labor and costs associated with sample preparation.
