The process begins by freezing the sample, reducing chamber pressure, and then applying controlled heat so ice transitions directly to vapor, which is captured on the cold trap.\u003c\/p\u003e\n\u003cp\u003eLower cold-trap temperatures enhance vapor capture and maintain a stable vacuum during primary drying. Secondary drying further reduces bound moisture to achieve the desired residual levels. Monitoring process curves ensures repeatable results across runs and provides reliable documentation for lab records.\u003c\/p\u003e\n\u003ch2\u003eFlask Freeze Dryer – QualiFD™ F Series Technical Specification\u003c\/h2\u003e\n\u003ctable class=\"table\" border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eQualiFD™ F\u003c\/th\u003e\n\u003cth\u003eOptions \/ Notes\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum cold trap temperature (no-load)\u003c\/td\u003e\n\u003ctd\u003e≤ -85 °C\u003c\/td\u003e\n\u003ctd\u003eOptional ≤ -110 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUltimate vacuum (no-load)\u003c\/td\u003e\n\u003ctd\u003e≤ 1 Pa\u003c\/td\u003e\n\u003ctd\u003eMeasured as empty load\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHanging bottle capacity\u003c\/td\u003e\n\u003ctd\u003e24 bottles\u003c\/td\u003e\n\u003ctd\u003eNon-standard customization available\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported flask types and sizes\u003c\/td\u003e\n\u003ctd\u003eConical: 100 \/ 250 \/ 500 \/ 1000 mL\u003c\/td\u003e\n\u003ctd\u003eWide-mouth: 600 \/ 1200 mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eT-frame material\u003c\/td\u003e\n\u003ctd\u003eSUS 304 stainless steel\u003c\/td\u003e\n\u003ctd\u003eUpgrade to SUS 316L available\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDefrost method\u003c\/td\u003e\n\u003ctd\u003eElectric defrost\u003c\/td\u003e\n\u003ctd\u003eListed as standard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData handling\u003c\/td\u003e\n\u003ctd\u003eCurve display + data export\u003c\/td\u003e\n\u003ctd\u003eUSB export noted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInert gas function\u003c\/td\u003e\n\u003ctd\u003eNitrogen filling valve\u003c\/td\u003e\n\u003ctd\u003eFor nitrogen or other inert gases\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Qualitest USA LC","offers":[{"title":"Default Title","offer_id":51847337115959,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/1859\/1543\/files\/flask-freeze-dryer1094279435.webp?v=1775050176","url":"https:\/\/qualitest.us\/ar\/products\/flask-freeze-dryer","provider":"Qualitest USA LC","version":"1.0","type":"link"}
