Winkler Bottle
A Winkler bottle is a piece of laboratory glassware specifically made for carrying out the Winkler test. These bottles have conical tops to aid in the exclusion of air bubbles when the top is sealed. This is important because oxygen in trapped air would be included in the measurement and would affect the accuracy of the test.

“A ship may belong to her captain, but the lifeboats belong to the crew.”
—John Farrow. Winkler (Claude Akins)
“Let us not succumb to nature. We will marshall the clouds and restrain tempests; we will bottle up pestilent exhalations; we will probe for earthquakes, grub them up, and give vent to the dangerous gas; we will disembowel the volcano, and extract its poison, take its seed out. We will wash water, and warm fire, and cool ice, and underprop the earth. We will teach birds to fly, and fishes to swim, and ruminants to chew the cud. It is time we looked into these things.”
—Henry David Thoreau (1817–1862)
