Graphite Digestion Blocks


DigiPREP systems are ideal for any digestion or heating method which requires a temperature below 180°C. Teflon® coated graphite block resists aggressive, corrosive attack for guaranteed long life. All Systems operate with a user friendly KeyPad or Color Touch Screen Controller.

The DigiPREP 240 series are ideal for high temperature digestions in Teflon® and glass vessels up to 240 ºC. This innovative Teflon® coated graphite block is made with a unique shape around the wells to prevent acid spills from migrating into the housing. These sysetms also have built in temperature control with temperature uniformity (at 95 ºC) of +/- 1.5 ºC and accuracy (at 240 ºC) of +/- 3.0 ºC. 

The DigiPREP 240 MS COMBI is an innovative design that incorporates a rectangular, Teflon® coated chamber for two graphite block inserts. Different size inserts are available as well as custom inserts upon request.

They describe acid digestion of samples in an open vessel environment for metals analysis by AA, GFAA, ICP and ICP-MS. These application notes are used as a first step to create your own personal sample digestion methods.

Examples of Application Notes available:

  • Digestion of SS-1 Soil CRM Samples following USEPA Method 3050b
  • Digestion of Animal Feed Samples following the AOAC 957.02 (a) Method
  • Digestion of Dried Epoxy Paint Chips
