CTDH40
UHV Booster CF40 Dewar
From
5’950.00 CHF
A LN2 dewar boosted cryopump to reduce pump-down times of small UHV chambers.
- Fast Pumpdown: Achieve UHV conditions within approximately 30 minutes after filling the dewar with LN2.
- No Bakeout Required: Eliminate the time and temperature constraints associated with traditional bakeout methods.
- Integrated Heating Coil: Quickly warm up the cold trap for efficient cycling.
- Temperature Monitoring: Built-in PT100 sensor allows for precise temperature monitoring during cooldown and warmup phases.
- Compact and Efficient: 0.5 liter LN2 capacity provides approximately 3 hours of operation.
The CTDH40 UHV Booster is a liquid nitrogen (LN2) cold trap designed to significantly accelerate pumpdown times in small transfer chambers, such as the VSCT40 Fast Pump Down Dock. This "cryopump" effectively reduces base pressure by a factor of 10, enabling rapid sample transfer from portable UHV suitcases into larger UHV systems without the need for lengthy bakeout procedures.
- Mounting Flange: DN40CF (2.75")
- Pumpdown Time (with VSCT40): ~30 minutes to 1E-8 mbar
- Temperature Sensor: Built-in Pt100 sensor
- Electrical Feedthrough: 6-pin, DN16CF (1.33") miniature feedthrough
- Dewar:
- Vacuum isolated with plastic lid
- LN2 Filling Volume: ~0.5 liters
- Cooling Temperature: 80K
- Cooling Blocks: Aluminium with OFCH core
