Why Choose the Parr 4748A 200 mL Acid Digestion Vessel?
The 4748A offers a robust solution for laboratories requiring high-throughput, high-integrity sample digestion. Designed with operator safety in mind, it includes a built-in rupture disc, strong flanged PTFE liner, and spring-sealed closure. To ensure safe operation, it’s recommended to remain well below its maximum limits of 250 °C and 1900 psi. For untested procedures, it is advisable to validate in a smaller vessel before scaling up to this size.
