Plastic Water Sampler PWS

Niskin-Type Plastic Water Sampler PWS features all plastic (PVC) design, consisting of a tube with two lids connected by a latex rubber tubing. The lids are kept open during descent, caring for a fair flushing of the sampling tube. The sampling tube is completely metal-free. The PWS on the one hand is the standard oceanographic sampler to be used on Multi Water Sampler/ Rosette/Carousel arrays and on the other hand it can be used as single or series instrument connected to a hydrographic wire. When used on a wire, a messenger, dropped down the wire from the surface, releases the end stoppers for closure. For the use of several PWS in a row a second messenger below the first sampler is used to actuate a series of samplers along the wire. When operated as a single instrument without bottom weight, we recommend to use a Centered Mounting Rack (436 380 … 436 395) which cares for a vertical position of the sampler. Retrieve the water sample via the discharge cock/tube at the lower end of the sampler

Combined Plate Chamber

Plankton sedimentation and counting chamber acc. to Utermoehl

About

as discribed in UNESCO’s Phytoplankton Manual (published 1978) the Combined Plate Chamber allows you to look at sedimented plankton samples from a very short distance l. How? Put the sample into a cylinder on top of the rectangular plexiglass plate with a thin base plate, let the fixed plankton concentrate and after sedimentation simply push the cylinder with excess liquid aside. The handling support underneath the plate will collect the extra water from the cylinder. You can now take the plate and examine the sample under an inverted microscope. Three calibrated cylinder sizes are provided with each set allowing to analyse different sample volumes

Bongo Net

Oceanographic double-ring net for horizontal or oblique tows

About

The double-ring construction not only avoids disturbances usually caused by the towing bridles fixed in front of the mouth opening of non-opening/non-closing plankton nets but it allows the investigator to work with two different mesh sizes at a time. Two 60 cm diameter stainless steel rings, connected by a coupling with rotatable connection point for the towing rope, are equipped with two 2.5 meter long net bags.

The Bongo Net should be operated in conjunction with a 22 kg V-Fin depressor to create negative lift at the instrument. For easy retrieval the samples are concentrated inside removable plastic net buckets with side window (covered with sieve gauze). Use the Bongo Net in conjunction with two Mechanical Flow Meters to measure the filtered water volume.
