DZF6210-HT 500°C High-Temperature Vacuum Oven with Integrated Vacuum Pump, 3-Zone Programmable Heating, 215 L Stainless Steel Chamber
DZF6210-HT is designed for laboratory processes requiring controlled vacuum drying, annealing, and nanomaterial preparation at elevated temperatures up to 500°C. Its spacious 215-liter chamber accommodates sizable samples while maintaining precise temperature uniformity, critical for consistent material treatment and research reproducibility.
The oven operates by creating a vacuum environment inside a robust stainless steel chamber, reducing oxidation and contamination risks during heating. Three independently controlled stainless steel heating plates provide zoned temperature regulation, allowing tailored thermal profiles across the chamber volume. This zoned approach supports complex workflows requiring differential heating within the same cycle.
Key Features
- 215 L chamber constructed from 1Cr18Ni9Ti stainless steel with welded bracing for durability
- Three separate SS304 heating plates with individual programmable temperature controllers (30 segments, ±1°C accuracy)
- Maximum continuous operating temperature range of 50–450°C; peak temperature of 500°C for up to 2 hours
- Integrated dual-stage rotary vane vacuum pump with exhaust filter achieving vacuum levels below 133 Pa (2 Torr)
- Built-in mechanical vacuum gauge and 1000 mL/min gas flowmeter for precise vacuum and gas flow monitoring
- Included digital-controlled recirculating water chiller (EQ-KJ5000) with 5–35°C refrigeration range and 16 L/min flow rate
- Safety note: samples must not contact heating plates directly; use ceramic sheets or stainless trays to hold samples
