Please note that you will need a <a href=\"\/product\/biochamber-2000\/\">BioChamber 2000<\/a> (<nobr>BC-2000<\/nobr>), and a <a href=\"\/product\/stir-station\/\">Stir Station<\/a> (<nobr>STIR<\/nobr>) with a magnetic stir bar.<\/p>\n<ol class=\"wp-block-list\">\n<li>Prepare and setup the Ethanol Sensor as described in the sensor booklet.<\/li>\n<li>If your CO\u2082 sensor has a switch, set it to the High (0-100,000 ppm) setting.<\/li>\n<li>Connect the sensors to the data-collection software.<\/li>\n<li>Place a BioChamber 2000 mL container on a stir station. Place a magnetic stir bar in the chamber. Add 250 mL of warm water to the chamber and turn on the stir station. Make sure the stir bar is spinning at a medium speed.<\/li>\n<li>Add 30 g of table sugar to the water in the chamber and allow it to dissolve.<\/li>\n<li>Add one tablespoon of baker&#8217;s yeast to the liquid in the chamber.<\/li>\n<li>Using a gentle, twisting motion, place the Ethanol Sensor equipped with split stopper into one of the openings in the BioChamber. Important: Use a ring stand and a clamp or electrode support to secure the sensor. Adjust the sensor so that the tip of the sensor is one cm above the level of the liquid.<\/li>\n<li>Using a gentle, twisting motion, place the CO\u2082 Gas Sensor in the other opening in the BioChamber.<\/li>\n<li>Begin data-collection.<\/li>\n<li>Determine the rate of CO\u2082 gas and Ethanol vapor production using the Linear Fit features in your data-collection software.<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"<p>If you want to use a Vernier CO\u2082 Gas Sensor and a Vernier ethanol sensor to show that CO\u2082 gas and Ethanol are both produced&#8230;<\/p>\n","protected":false},"author":8971,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[],"tags":[860,4785,4772,4786,4783],"class_list":["post-2862","post","type-post","status-publish","format-standard","hentry","tag-co2","tag-eth","tag-eth-bta","tag-fermentation","tag-gdx-etoh"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/2862","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/users\/8971"}],"replies":[{"embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/comments?post=2862"}],"version-history":[{"count":0,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/2862\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/media?parent=2862"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/categories?post=2862"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/tags?post=2862"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
