Birge Closing Net 80um with Bucket, no carry case.

Birge Closing Net 80um with Bucket, no carry case.

Birge Closing Net 80um with Bucket, no carry case.

Ideal for vertical plankton tows when you need to sample a specific stratum in an integrated water column.

After you’ve reached your desired depth and taken your sample, close the net by sending a messenger down the line, ensuring no further water gets through. Raise vertically at an even speed of 0.5 m/s. The truncated design improves filtration efficiency and consists of four parts: a tapered upper cylinder, the closing portion; a conical filtering net; an attached dolphin adapter; and a stainless steel Wisconsin dolphin bucket whose 10 oz. weight insures the net’s rapid descent. The closing portion consists of top nickel plated brass spring attached to a bridle, towing eye and release tab. A separate lowering and retrieval line is attached to the middle ring between the two cones.

Includes:

• Birge Closing Net 80 um mesh (3-21-C30)
• Adapter (3-48-C60)
• 200 mL Wisconsin Bucket 80 um mesh (3-40-D80)
• Polyester 3/16" line 100ft hank (3-62-C15)
• Messenger, Solid 8 Oz SS (3-46-D80)
