A fermentation lock or fermentation airlock is a device used in beer brewing and wine making that allows carbon dioxide released during fermentation to escape the fermenter, while not allowing air to enter the fermenter, thus avoiding oxidation. There are two main designs for the fermentation lock. These designs work when half filled with water.
In brewing, a carboy or demijohn is a glass or plastic vessel used in fermenting beverages such as wine, mead, cider, perry, and beer. Usually it is fitted with a rubber stopper and a fermentation lock to prevent bacteria and oxygen from entering during the fermentation process. During the homebrewing process, a primary carboy is used for ...
'S' trap inlet to drain [further explanation needed]. The air lock phenomenon can be used in a number of useful ways. An 'S' trap (a pipe that descends from a reservoir, then curves back up, then down again) allows liquid to flow from top to bottom unhindered, and gas cannot flow through the trap unless it has enough extra pressure to overcome the liquid head of the trap.
An airlock room is needed to decompress astronauts after they suit up in specialized space suits in preparation for extravehicular activity, and then to recompress them upon return. [5] Airlocks such as the Nanoracks Bishop Airlock also allow payloads to be released into space with minimal air loss. Skylab orbital workshop trash disposal airlock
The Nanoracks Bishop Airlock is a commercially funded airlock module launched to the International Space Station on SpaceX CRS-21 on 6 December 2020. [3] [4] It was berthed to the Tranquility module on 19 December 2020 by the Canadarm2. [5] The module was built by Nanoracks, Thales Alenia Space, and Boeing. [6]
Bent connecting rod after hydrolock Same connecting rod, turned 90°. Hydrolock (a shorthand notation for hydrostatic lock or hydraulic lock) is an abnormal condition of any device which is designed to compress a gas by mechanically restraining it; most commonly the reciprocating internal combustion engine, the case this article refers to unless otherwise noted.
A laboratory rubber stopper or a rubber bung or a rubber cork is mainly used in chemical laboratories in combination with flasks and test tube and also for fermentation in winery. [ 1 ] [ 2 ] [ 3 ] Generally, in a laboratory , the sizes of rubber stoppers can be varied up to approximately 16 sizes and each of it is specific to certain type of ...
Since its introduction into the European market in 2003, over 300 wineries have utilized the closure. Using a glass stopper with an inert o-ring, the closure is claimed to create a hermetic seal that prevents oxidation and TCA contamination. A disadvantage of the closure is the relatively high cost of each plug (70 cents each) and cost either ...
