SML sampler

A cheap, but efficient prototype of sea surface microlayer (SML) drum sampler is constructed.

Main characteristics:

• PVC pipes as main construction base
• PMMA sampling cylinder (40 cm diameter)
• PTFE/PC wiper
• variable rotation using 12 V battery powered gear electromotor (up to 15 rpm)
• ~5-10 L of SML in 1 h
• adaptable depth of surface sampling
• easy mounting/dismounting
• adaptable for mounting additional devices (e.g. CTD multiprobe)
