LAB1ST VOS200 series is an integrated vacuum drying oven engineered for precise and reliable control of both temperature and vacuum. It comes with a built-in vacuum pump and desiccant tank for simplified operation, and supports programmable vacuum and temperature cycles, making it an ideal solution for drying heat-sensitive and easily oxidized materials.

With a digital pressure sensor and microcomputer-controlled vacuum system, the VOS200 ensures efficient and repeatable drying processes.

Features:

• Key Features
  
  • Fully Integrated Plug-and-Play Design: Includes a built-in vacuum pump and desiccant tank for immediate operation
  • Standard Programmable Control: Offers comprehensive control over heating, vacuum, nitrogen purge, and time, including temperature ramp rate (slope) control for precise process management
  • Rectangular Chamber Design: Maximizes usable workspace volume
  • Tempered & Bullet-Proof Double-Layer Glass Door: Provides clear visibility into the chamber; compatible with inert gas injection
    
  • Adjustable Door Seal & Integrated Silicone Gasket: Maintains high vacuum integrity
  • Stainless Steel Interior: Durable, long-lasting, and easy to clean
  • Oxygen-Free Operation: Suitable for storage, heating, testing, and drying under inert or vacuum conditions to prevent oxidation
  • Reduced Drying Time: Cuts drying time by over 50% compared to  conventional vacuum drying ovens
• Drying Process Control
  
  • The vacuum drying process can be programmed with customizable vacuum cycles. Users can set upper and lower vacuum limits to further shorten drying times. For example:
    
  • Minimum Vacuum: 50Pa
  • Maximum Vacuum: 900Pa
  • Cycle Count: Up to 99 cycles
  • As cycles progress, humidity decreases rapidly, significantly accelerating drying
• Programmable Cycle Control
  
  • User-friendly interface with direct programming capability
  • Supports up to 15 program segments, each configurable from 1 to 9999 minutes
  • Pre-set startup and shutdown timers for automated operation
• Vacuum Control
  
  • Digital vacuum control with auto-regulation via digital vacuum gauge
  • Adjustable vacuum range: 10–105Pa (minimum achievable vacuum: 133Pa)
  • Control accuracy: ±1%
  • Resistant silicon piezoresistive sensor ensures stable pressure readings, unaffected by airflow
• Temperature Control Advantages
  
  • 15-Segment Programmable Profiles:
  • Standard temperature and hold-time settings ("Temperature – Dwell Time")
  • Ramp rate control using "Temperature–Time–Temperature" format for precise heating/cooling rate management
  • Full control over every stage: heating, holding, and cooling
  • Heating Methods: Chamber heating or shelf heating
