Linde Super-30 Cryogenic Liquid Nitrogen Dewar

For laboratories that routinely use liquid nitrogen but don't require a permanent cryogenic storage freezer, a high-quality transport dewar provides the ideal balance of portability, holding time, and ease of use. The Linde Super-30 Cryogenic Dewar has long been recognized as a dependable solution for storing and dispensing liquid nitrogen, making it well suited for laboratories performing cryogenic sample handling, cold bath preparation, cryopreservation procedures, and laboratory transport of liquid nitrogen.

With an approximate 30-liter liquid nitrogen capacity, the Linde Super-30 offers significantly longer holding times than smaller laboratory Dewars while remaining compact enough for everyday use. Its vacuum-insulated construction minimizes evaporation losses, making it an excellent choice for biotechnology companies, pharmaceutical manufacturers, hospitals, universities, IVF laboratories, and research facilities that regularly handle liquid nitrogen but do not require an automated storage system.

Many laboratories use a transport dewar like the Super-30 alongside cryogenic storage systems for long-term specimen preservation, controlled-rate freezers for optimized freezing protocols, ultra-low freezers for intermediate storage, and biosafety cabinets during sample preparation.

Linde Super-30 Overview

The Linde Super-30 is designed for laboratories that need a dependable source of liquid nitrogen for daily laboratory operations. Unlike automated cryogenic storage systems intended for long-term preservation of thousands of samples, the Super-30 functions as a versatile working dewar that allows laboratory personnel to safely transport, dispense, and temporarily store liquid nitrogen wherever it is needed.

Its vacuum-insulated aluminum vessel minimizes heat transfer to reduce nitrogen boil-off while maintaining a relatively lightweight design that is easy to move between laboratory work areas. The combination of portability and long holding time makes the Super-30 particularly useful for laboratories that support multiple cryogenic procedures throughout the day.

Common Applications

The Linde Super-30 is commonly used for:

Transporting liquid nitrogen throughout the laboratory
Filling cryogenic storage systems
Preparing cryogenic cooling baths
Controlled-rate freezing procedures
Temporary storage of liquid nitrogen
Cooling laboratory components
Supporting IVF and reproductive laboratories
Cryogenic sample handling

Ideal Laboratory Types

The Super-30 is well suited for:

Biotechnology companies
Pharmaceutical manufacturers
IVF laboratories
Hospitals
Universities
Academic research laboratories
Clinical laboratories
Cell therapy laboratories
Materials science laboratories

Laboratories that frequently work with liquid nitrogen will appreciate the Super-30's combination of portability, durability, and dependable thermal performance.

Why Choose a Portable Liquid Nitrogen Dewar?

Large cryogenic storage systems are designed to preserve biological samples for months or years, but many laboratories also require a practical way to move liquid nitrogen between storage vessels, laboratory benches, and freezing equipment. A portable dewar like the Linde Super-30 fills that role by providing excellent insulation and manageable capacity without requiring electrical power or complex controls.

Its size makes it particularly useful for laboratories that routinely refill smaller vessels, prepare cryogenic baths, or support multiple workstations using a single liquid nitrogen supply.

Typical Uses

The Super-30 is commonly used for:

Liquid nitrogen transport
Cryogenic sample handling
Controlled-rate freezing support
Cold bath preparation
Laboratory equipment cooling
Temporary cryogenic liquid storage

For long-term biological specimen preservation, dedicated cryogenic storage systems remain the preferred solution.

Operating Costs & Maintenance

The Super-30 operates without electrical power or mechanical refrigeration. Operating costs are limited primarily to liquid nitrogen consumption, while the vacuum-insulated vessel minimizes evaporation during storage. Routine maintenance generally consists of inspecting the vessel for physical damage, ensuring the neck opening remains clean, and periodically evaluating vacuum performance through normal evaporation rates.

Specifications compiled from Linde cryogenic equipment literature and American Instrument Exchange product information.

Inspection & Preparation

Every Linde Super-30 offered by American Instrument Exchange is inspected before shipment. Our technicians examine the vacuum vessel, neck assembly, carrying handles, and overall structural condition. Each unit is then filled with liquid nitrogen and monitored to verify acceptable evaporation performance and proper vacuum integrity before being thoroughly cleaned and prepared for delivery.

Laboratories purchasing transport dewars frequently pair them with cryogenic storage systems, ultra-low freezers, biosafety cabinets, laboratory refrigerators, and centrifuges from American Instrument Exchange.

Shipping & Handling Considerations

The Linde Super-30 ships from American Instrument Exchange after inspection and testing. Before placing the dewar into service, laboratories should establish appropriate cryogenic safety procedures, including the use of insulated gloves, face protection, and adequate room ventilation. Facilities should also follow recommended practices for transporting and dispensing liquid nitrogen to minimize evaporation losses and ensure operator safety.

Frequently Asked Questions

What is the Linde Super-30 primarily used for?

The Super-30 is designed for transporting, storing, and dispensing liquid nitrogen for laboratory procedures, cryogenic sample handling, and filling larger cryogenic storage systems.

Does the Super-30 require electricity?

No. The Super-30 is a passive vacuum-insulated dewar that stores liquid nitrogen without compressors, refrigeration systems, or electrical power.

Is the Super-30 intended for long-term biological sample storage?

No. It is designed primarily as a working and transport dewar. Long-term specimen preservation is better accomplished using dedicated cryogenic storage systems designed specifically for sample storage.

How is the Linde Super-30 tested before shipment?

Every refurbished Linde Super-30 is inspected and tested by American Instrument Exchange. The vessel is filled with liquid nitrogen and monitored to verify vacuum integrity and acceptable evaporation performance before shipment.

Testing Procedures for Used and Refurbished Laboratory Freezers

Cold Storage Reliability from American Instrument Exchange

At American Instrument Exchange, every used and refurbished laboratory freezer we offer undergoes a comprehensive multi-point testing protocol to ensure optimal performance, temperature stability, and long-term reliability. Our rigorous testing procedures are designed to meet the demanding standards of biomedical, pharmaceutical, research, and clinical environments—so you can trust your freezer to protect your valuable samples and materials.

Why Testing Refurbished Laboratory Freezers Is Critical

Before any laboratory freezer is placed back into service, it must be carefully tested for:

Consistent temperature control and uniformity across internal zones
Compressor functionality and refrigeration system performance
Seal integrity and insulation efficiency to prevent temperature loss
Electrical safety and alarm system operation

Thorough testing minimizes the risk of temperature excursions, equipment failure, and product loss—especially for temperature-sensitive items like reagents, biological samples, and vaccines.

Our structured testing protocol ensures that all used and refurbished laboratory freezers meet or exceed manufacturer specifications and industry expectations.
