Material Specifications

AISI 316
Stainless.

Almost our entire range of sediment sampling equipment is manufactured from premium AISI 316 stainless steel with an electro-polished finish.

This ensures maximum resistance against corrosion in harsh marine and freshwater environments, guaranteeing a long operational lifespan and preventing sample contamination.
