Frequently asked questions
Is the Wallach UltraFreeze Dewar compatible with other liquid nitrogen sprayers?
The Wallach UltraFreeze Dewar is specifically designed to work with the UltraFreeze Liquid Nitrogen Sprayer (#900076), ensuring optimal compatibility and performance.
Is this Dewar ideal for medical environments?
The Wallach UltraFreeze Dewar is primarily designed for medical and laboratory environments that require secure and controlled cryogenic handling. Its intended uses include:
- Liquid Nitrogen Storage: It serves as a durable storage reservoir for liquid nitrogen, maintaining its integrity for an extended duration when properly sealed.
- Refill Tank: It is specifically engineered to work in conjunction with the UltraFreeze Liquid Nitrogen Sprayer (#900076) for cryosurgical procedures.
Which accessory is required for the 10 Liter Dewar?
The 10 Liter (as well as the 20 Liter) Wallach UltraFreeze Dewar requires a separate device to safely discharge liquid nitrogen into the compatible UltraFreeze Sprayer (#900076).
- Required Accessory: Dewar Manual Discharge Device
- Compatible Part Numbers: #900111-1 or #900111-3
Note: This Manual Discharge Device is a necessary component for operation and is sold separately from the Dewar unit.
What discharge device is needed for the 5 Liter Dewar?
For the 5 Liter Wallach UltraFreeze Dewar, you will need the Dewar Pouring Spout (#900110-1). Please note that pouring mechanisms are sold separately.
Does the Dewar ensure long-term liquid nitrogen storage?
Yes, the Wallach UltraFreeze Dewar is engineered for secure containment, allowing liquid nitrogen to remain viable for an extended period when the unit is properly sealed. This long-term storage capability is a key benefit.
It is important to note the difference between storage and active usage in the connected sprayer:
- Sealed Storage (In Dewar): Liquid nitrogen maintains its integrity for a long duration.
- Active Use (In UltraFreeze Sprayer #900076): Once transferred to the compatible UltraFreeze Sprayer, the documented liquid evaporation time is approximately eight hours.
Are separate pouring mechanisms required?
Yes, the pouring mechanisms and discharge devices (often shown as the blue top assemblies) are not included with the Dewar tank and must be purchased separately. These accessories are essential for safely dispensing the liquid nitrogen and ensuring compatibility with the UltraFreeze Liquid Nitrogen Sprayer (#900076). The specific accessory required depends entirely on the capacity of the Dewar you select (5 Liters, 10 Liters, or 20 Liters).
What storage capacities are offered?
The Wallach UltraFreeze Dewar is available in three sizes designed for different liquid nitrogen storage requirements:
- 5 Liters
- 10 Liters
- 20 Liters
What components are included with the UltraFreeze Dewar?
The purchase includes only the Wallach UltraFreeze Dewar storage refill tank in the capacity you select (5 Liters, 10 Liters, or 20 Liters).
It is important to note that the necessary pouring and manual discharge devices for safely dispensing liquid nitrogen are not included and must be purchased separately based on the Dewar size.
Does this dewar utilize professional-grade materials for durability?
Yes, the Wallach UltraFreeze Dewar is built with professional-grade construction to ensure reliable, long-term performance in demanding clinical settings. Its industrial design focuses on:
- High-quality metallic build: Designed for stability and safety when handling liquid nitrogen.
- Precision-engineered fittings: The unit features robust construction to maintain structural integrity throughout its service life.
- Reliable storage: Specifically engineered to minimize premature evaporation when properly sealed.
