Manufactured using virgin polypropylene, verified for leachable metals by ICP-MS. Low leachable catalytic/additive metal content, excellent visibility and good acid resistance are guaranteed.
DigiTUBEs come complete with leak free, polyethylene screw caps with no metallic additives. The volume lines on 50ml DigiTUBEs were calibrated in accordance with ASTM Standard E542-01. The accuracy of all lines exceed the tolerance specifications of ISO 6706, Plastics laboratory ware – Graduated measuring cylinders, and meet the following tolerance requirements of ASTM Standard E1272, Standard Specification for Laboratory Glass GraduatedCylinders: +/- 0.25ml for all volume lines on 50ml tubes (Class A). This reduces and eliminates the need for graduated cylinders and volumetric flasks.
In fact, a DigiTUBE replaces 5 vessels in the lab (i.e. digestion beaker, graduated cylinder, volumetric flask, autosampler tube, and storage container). Save time and lower costs with the use of DigiTUBEs.
Second generation DigiTUBEs offer a flatter bottom than previous models providing a more intimate contact with the base of the DigiPREP well. This results in faster sample temperature response times. Use Racklock DigiTUBEs for easy one-handed closer of screw cap digestion tubes when used in conjunction with our DigiPREP systems.
Note: For use with 50ml DigiPREP systems.
