Overview

HGJ Series Laboratory Vacuum Freeze Dryer by Yuanhuai utilizes the coordinated operation of the freezing system, vacuum system, and control system to freeze liquid or solid substances and transform them into dried solids through pressure reduction evaporation. This series of freeze dryers comes in four basic configurations: standard type, manifold type, press-cover type, and manifold press-cover type. It features programmable programming, allowing for the automation of controls from freezing to defrosting. Items treated with freeze-drying are easy to store for an extended period and can be rehydrated to their pre-freeze-dried state with the retention of their original biochemical characteristics.

Features

  • Integrated structure design, compact, practical, and leak-free.

  • All materials in contact with the product use inert materials, meeting GLP requirements.

  • The cold trap and drying rack are made of stainless steel, corrosion-resistant, and easy to clean.

  • The cold trap has a large opening, with no internal coil, and features a sample pre-freezing function, eliminating the need for a low-temperature freezer.

  • Utilizes gas diversion technology for uniform ice trapping in the cold trap and strong ice trapping capability.

  • The compressor is environmentally friendly, energy-efficient, has a long service life, and operates with low noise.

  • The vacuum pump has a high pumping speed, achieving a higher ultimate vacuum.

  • The vacuum pump has a protection function, allowing the setting of the cold trap temperature for vacuum pump start, extending the vacuum pump's service life.

  • 7-inch full-color industrial embedded touch screen + SH-HPSC-II modular controller for high control precision and stable, reliable performance.

  • Intelligent data recording system that records and displays real-time temperature curves of the cold trap, sample temperature curves, and vacuum degree curves. Data can be exported for viewing and printing via computer.

  • User level and password settings can be configured for controlled operational management.

  • Powerful sensor calibration function, ensuring the accuracy of measurements over long-term use.
