Learn about the different types of flask dewars.
Lab Grade Glass Flask Dewar:
- Superior Insulation: Rigorous bakeout procedures and high-level evacuation (10-5 torr or better) guarantee exceptional thermal insulation, minimizing heat transfer and extending the lifespan of your materials.
- Enhanced Safety: Shielded evacuation tips offer increased protection against breakage and injury.
- Maximum Stability: Weighted bases across all models ensure stability, preventing accidental spills and hazards.
- Optional Added Protection: Choose full-length metal housings on most models for extra durability in demanding laboratory environments.
- Efficient Design: Cylindrical Dewars are constructed without internal pads, eliminating potential heat transfer points for optimal performance.
- Minimized Evaporation: Included stoppers create a tight seal, reducing evaporation and preserving your valuable materials.
- Practical Construction: Protective aluminum bases extend the full height of the Dewars for complete coverage. Vacuum tip-off tubulations are strategically offset to allow for convenient use with magnetic stirrers.
- Expanded Range: Our hemispherical Dewar line has been expanded to accommodate a wider range of flask sizes.
Flask Dewars with Handles
Handled Dewar vacuum flasks are the perfect choice for temporary storage and safe handling of liquid gases, particularly Liquid Nitrogen. Here's why:
- Easy Access: Wide-mouth design and fully silvered borosilicate glass inner flask ensure quick and convenient access.
- Sturdy Construction: Durable aluminum housing extends the full length for maximum protection, while a cushioned base provides stability.
- Efficient Design: Vacuumed to -5 torr for superior insulation and extended holding times.
- User-Friendly: Features a coated handle for comfortable grip and a specially designed lip for effortless pouring.
- Evaporation Control: Includes a vented polyethylene stopper to minimize evaporation loss.
Ideal for laboratory environments where safe and efficient Liquid Nitrogen management is essential.
