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.
Tubes are graduated, in 5 ml increments, up to the 50 ml graduation mark. The 50 ml graduation mark is certified accurate to ±0.25 ml in accordance with ASTM Class "A" volumetric standards. 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.
Products meet the following tolerance requirements of ASTM Standard E1272.
+/- 0.10 ml for the 5, 10 and 15 ml volume lines on 15 ml Autosampler tubes (Class A)
+/- 0.10 ml for the 15 ml volume line on 15 ml tubes (Class A)
+/- 0.25 ml for all volume lines on 50 ml tubes (Class A)
+/- 0.50 ml for 50 ml and 100 ml volume lines on 100 ml tubes (Class A)
