These are high quality glass tubes designed for heated, acid-based, vacuum hydrolysis of proteins and peptides for amino acid analysis. It fits conveniently into reacti-block aluminium heating blocks.

• Fits into Reacti-Block aluminium heating blocks
• Sufficient for samples up to 0,35 ml
• Optimal hydrolysis control

The upper temperature limit of the vacuum hydrolysis tubes is 260 °C, however, do not heat the tubes greater than 100 °C in an oven.
