{"product_id":"copy-of-dynacal-permeation-tube","title":"Custom Dynacal Permeation Tubes","description":"\u003cp\u003eDynacal perm tubes and wafer permeation devices are small, inert capsules containing a pure chemical compound in a two-phase equilibrium between its gas phase and its liquid or solid phase. At a constant temperature, the device emits the compound through its permeable portion at a constant rate. Perm tubes and wafer devices are typically inserted into a carrier flow to generate test atmospheres for calibrating gas analyzer systems, testing hazardous gas alarms, or conducting long-term studies of effects on materials or biological systems – in short, any situation requiring a stable concentration of a specific trace chemical.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003ca title=\"VICI Metronics Dynacal Permeation Tube Brochure\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0262\/9389\/5223\/files\/Metronics_Dynacal_Permeation_Tubes_3.pdf?v=1639188528\"\u003eDownload Brochure\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cstyle\u003e\u003c!--\n@media screen and (min-width: 641px) {\n  .table th, .rte table th,\n  .table td,\n  .rte table td {\n    padding: 5px 3px;\n    }\n    .table th:first-child, .rte table th:first-child,\n    .table td:first-child,\n    .rte table td:first-child {\n      padding-left: 3px;\n      }\n    .table th:last-child, .rte table th:last-child,\n    .table td:last-child,\n    .rte table td:last-child {\n      padding-right: 30px; } }\nspan {\n  display: block;\n}\n--\u003e\u003c\/style\u003e","brand":"VICI Metronics","offers":[{"title":"Default Title","offer_id":40163582181431,"sku":null,"price":195.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0262\/9389\/5223\/files\/DYNACALPERMEATIONTUBES-500x500_777091c5-cc62-4da9-9b95-f578e1f4eee4.png?v=1684534541","url":"https:\/\/www.vicimetronics.com\/products\/copy-of-dynacal-permeation-tube","provider":"VICI Metronics","version":"1.0","type":"link"}
