Vacuum Bag Sealer
About

Process: This is a heavy-duty vacuum heat sealer designed for creating air-tight, moisture-free packages for sensitive samples, wafers, or devices. It supports N₂ purging before sealing to displace oxygen and moisture, providing inert atmosphere storage or shipping protection.
Hardware: 36" (914 mm) maximum sealing width for large bags or multiple items. Automated sequence: purge (N₂ or air), vacuum draw, heat seal, and cool-down. Foot lever operation for hands-free control. Adjustable vacuum level, seal time, and temperature. Robust construction for cleanroom or lab use.
Key Features:
- Max sealing width: 36"
- Automated cycle: N₂ purge → vacuum → heat seal → cool
- Operation: Foot lever (hands-free)
- Gas: N₂ purge capability (inert backfill before sealing)
- Seal quality: Strong, uniform heat-seal bar
Applications:
- Long-term storage of moisture/oxygen-sensitive wafers or devices
- Inert atmosphere packaging (N₂ backfill) for transport or shipping
- Vacuum-sealing of samples for glovebox transfer or contamination control
- Protection of hygroscopic materials or chemicals
- Cleanroom-compatible sample preservation
Usage: Place sample in vacuum-sealable bag, position bag in sealer (seal area clean), close lid, select cycle (purge/vacuum/seal), press foot lever to start automated sequence, wait for completion, remove sealed bag. Inspect seal integrity. Clean sealing bar after use.

Recipes & Data
- Standard Sealing: Common process:
* N₂ purge cycle: 5–30 seconds (displace air/moisture) * Vacuum level: High vacuum for air removal * Seal time/temperature: Adjust per bag material (typically 2–5 seconds at 120–180°C) * Cool-down: Automatic to ensure strong bond
- Process Control: Visually inspect seal for uniformity and leaks. Test bag integrity (e.g., vacuum retention). Label bags with date/sample info.
- Notes: Use anti-static or moisture-barrier bags for sensitive devices. Ensure sealing area is clean (no particles/oils). N₂ purge essential for oxygen-sensitive samples.
