A choice of two pyknometers is provided: the Gay-Lussac pyknometer and the Reischauer pyknometer. The principle by using the Gay-Lussac pyknometer consists in determination of the capacity by measuring the mass of water at 20 \u00b0C and measuring the volume of sample at 20 \u00b0C. Principle of the Reischauer pyknometer: calibration by measuring the masses of water*introduced up to the different graduation lines. Measurement of the mass of the volume of sample at 20 \u00b0C up to a certain graduation line. Both of the types: calculation of the quotient which results from dividing the mass of the sample by the volume of the pyknometer corresponding to this mass.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Purified glycerol for industrial use \u2014 Determination of density at 20 degrees C<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/iso\/\"><b>ISO<\/b><\/a><\/td>\n<td>1972-06<\/td>\n<td>6<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":604773,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[1019,2634],"product_tag":[],"class_list":{"0":"post-604761","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-71-080-60","7":"product_cat-iso","9":"first","10":"instock","11":"sold-individually","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/604761","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/604773"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=604761"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=604761"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=604761"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
