This all-in-one system minimizes contamination risk by integrating pre-freezing, sublimation, and drying within a single chamber. Both manual and automated modes allow flexibility for process development and routine batch operations.\u003c\/p\u003e\n\u003cp\u003eWith recipe-driven control, the QualiFD™ Adv EH manages freezing, sublimation, and vacuum drying efficiently. A transparent acrylic chamber door enables full observation of the process, while a safety diaphragm valve allows controlled inert gas backfill after drying.\u003c\/p\u003e\n\u003cp\u003eEnhanced cold-trap ice capture is achieved through a gas diversion system, and PID-controlled shelves maintain uniform temperatures for even drying. The unit features a 7-inch true-color industrial touchscreen with storage for hundreds of recipes, including multi-segment temperature programming for optimized freeze-drying cycles.\u003c\/p\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cp\u003eConventional lab samples (liquids, pastes, solids): The QualiFD™ Adv EH Advanced Electric Heating Freeze Dryer is ideal for freeze-drying a wide range of laboratory materials, including liquids, pastes, and solids. It supports typical lab workflows for improving storage stability, enabling safe transport, or preparing samples for downstream analysis.\u003c\/p\u003e\n\u003cp\u003eMethod development and scale-up studies: Manual operation allows precise experimentation with cooling rates, shelf temperature ramps, and vacuum conditions. Multi-segment temperature programming and recipe storage help teams reproduce cycles consistently and document variations during process development.\u003c\/p\u003e\n\u003cp\u003eRoutine batch processing with controlled documentation: Automatic mode enables consistent, repeatable freeze-drying once a cycle is defined. Real-time monitoring of key parameters, along with data export capabilities, ensures accurate reporting, trend analysis, and process verification.\u003c\/p\u003e\n\u003ch3\u003eStandards\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eISO 13408-3:2006 – Defines requirements and guidance for controlling and validating lyophilization processes in aseptic applications.\u003c\/li\u003e\n\u003cli\u003eASTM E3250-21 – Provides best practices for freeze dryer instrumentation, focusing on accurate measurement of product temperature and chamber pressure\u003c\/li\u003e\n\u003cli\u003eIEC 61010-1 – Specifies general safety requirements for electrical laboratory, measurement, and control equipment to ensure safe operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKey Features – Advanced Electric Heating Freeze Dryer (QualiFD™ Adv EH Series)\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated Pre-Freezing and Drying Workflow: Supports automated freeze-drying and sublimation within a single chamber.\u003c\/li\u003e\n\u003cli\u003eTransparent Acrylic Chamber Door: Allows full observation of the freeze-drying process during operation.\u003c\/li\u003e\n\u003cli\u003eSafety Diaphragm Inflation Valve: Enables controlled inert-gas connection and post-drying backfill.\u003c\/li\u003e\n\u003cli\u003eGas Diversion System: Promotes even ice capture in the cold trap for consistent drying results.\u003c\/li\u003e\n\u003cli\u003ePID Shelf Temperature Control: Minimizes shelf temperature differences, ensuring uniform drying.\u003c\/li\u003e\n\u003cli\u003e7-Inch Industrial Touchscreen: Features modular controller architecture for reliable, stable operation.\u003c\/li\u003e\n\u003cli\u003eRecipe-Based Control: Stores hundreds of recipes, each with up to 36 temperature control segments for precise cycle management.\u003c\/li\u003e\n\u003cli\u003eReal-Time Data Monitoring: Displays critical parameters during operation and allows export for analysis, reporting, and record-keeping.\u003c\/li\u003e\n\u003cli\u003eAlarm System: Visual and historical alarm queries support quick diagnosis and maintenance.\u003c\/li\u003e\n\u003cli\u003eUser Access Management: Password-protected settings ensure controlled operation and secure process management.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTheory and Method\u003c\/h2\u003e\n\u003cp\u003eFreeze-drying begins by freezing the material, followed by lowering the chamber pressure to allow ice to sublimate directly from solid to vapor. Controlled shelf heating provides the energy required during primary drying, while the cold trap captures vapor to maintain a stable vacuum environment. Secondary drying continues under carefully regulated temperature and vacuum conditions to remove residual bound moisture.\u003c\/p\u003e\n\u003cp\u003eThe system allows precise control over the cooling rate during pre-freezing, as well as sample warming and vacuum adjustments throughout sublimation and desorption stages. Continuous recording of temperature and vacuum profiles enables comparison between cycles and supports process optimization and refinement.\u003c\/p\u003e\n\u003ch2\u003eAdvanced Electric Heating Freeze Dryer – QualiFD™ Adv EH 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™ Adv EH\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFreeze drying area\u003c\/td\u003e\n\u003ctd\u003e0.6 m²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCold trap temperature\u003c\/td\u003e\n\u003ctd\u003e≤ -60 °C (no-load), optional ≤ -80 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVacuum level\u003c\/td\u003e\n\u003ctd\u003e≤ 5 Pa (no-load)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShelf temperature range\u003c\/td\u003e\n\u003ctd\u003e-50 to +70 °C (no-load), optional -70 to +70 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater capture capacity\u003c\/td\u003e\n\u003ctd\u003e≥ 10 kg\/24 h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial tray size\u003c\/td\u003e\n\u003ctd\u003e335 × 295 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of material trays\u003c\/td\u003e\n\u003ctd\u003e6 pcs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShelf size\u003c\/td\u003e\n\u003ctd\u003e340 × 300 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShelf spacing\u003c\/td\u003e\n\u003ctd\u003e50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall power\u003c\/td\u003e\n\u003ctd\u003e4500 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e450 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W×D×H)\u003c\/td\u003e\n\u003ctd\u003e795 × 895 × 1535 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoadable materials\u003c\/td\u003e\n\u003ctd\u003e6 L\/kg (material thickness 10 mm reference)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDefrost mode\u003c\/td\u003e\n\u003ctd\u003eNatural defrosting (optional electric defrost)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003eThree-phase 5-wire, 380 V\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":51838933238071,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/1859\/1543\/files\/advanced-electric-heating-freeze-dryer27031134.webp?v=1774898614","url":"https:\/\/qualitest.us\/es\/products\/advanced-electric-heating-freeze-dryer","provider":"Qualitest USA LC","version":"1.0","type":"link"}
