BOD Stopper, Glass Pennyhead, Replacement for 60 or 300 mL B

BOD Bottle Racks are constructed of coated wire. 1215X63 is holds up to twenty 60 mL BOD Bottles and 1220C96 hold up to twelve 300 mL BOD Bottles. Rubber Leash For BOD Stopper (1234R64) ensures that the stoppers do not become lost when collecting samples in from the field. The 10 mm diameter holes at each end of the leash expand to fit securely around both the stoppers and the bottle necks. Polyethylene cap with a closed cell foam insert (1781N85) snaps firmly over the flared mouth of Wheaton BOD bottles. This closure prevents the evaporation of the water seal during the five-day BOD incubation period. The foam insert fits into the cap and exerts pressure on the bottle stopper to hold it securely in place. BOD Bottle Aerator (1233M50) has a 40-60 micron porosity glass frit. It is made of low extractable borosilicate glass and is for use for use with 300 mL bottle. It is used in the EPA Method 245.1 Manual Cold Vapor Technique. Replacement Stoppers are available in Pennyhead (1234R62) or Robotic (1234R63) styles.
