Cetor3000 Datasheet 

Plankton, Sediment, Nutrient Sampler

The Cetor3000 Plankton Sampler, developed in partnership with CSHEL at the University of Delaware, can be deployed in oceans and lakes  for up to six months to collect and preserve up to 600 independently sealed samples. Three puck banks enable series filtration for up to 200 bacteria-grade samples and flow-path sterilization, provides zero cross-contamination.

Plankton, geochemical tracers, and suspended sediments are captured on user-selected mesh or membrane filters within reusable pucks. Sampling can be triggered manually or autonomously and is designed to operate without service for up to six months.

BenefitsCetor3000
