Frosty Fortunes: Prioritizing Quality and Avoiding Cheap Freezer Traps

Subzero Solutions: Choosing the Right Cryogenic Freezer

Before examining the challenges associated with navigating the cryogenic freezer market, it is important to understand which cryogenic freezer aligns most suitably with your needs. Cryogenic freezers are available in various sizes, storage capacities, operating temperature ranges, energy efficiency ratings, and storage methods. For those wishing to preserve biological samples using liquid nitrogen (LN₂), there are two main storage methods:

1. Vapor-phase storage
2. Liquid-phase storage

Immersion in LN₂, while commonly used for cryogenic storage, presents several drawbacks compared to vapor-phase cryogenic freezers. One significant concern is the risk of contamination, which is more pronounced in liquid-phase freezers due to the direct contact between samples and the LN₂. Vapor-phase cryogenic freezers mitigate this risk by maintaining samples above the LN₂ level, minimizing the chances of contamination. Additionally, vial explosions pose a potential danger in liquid-phase storage, where even a single drop of LN₂ entering a sample vial can lead to vial explosions upon warming. In contrast, vapor-phase storage eliminates this risk, as samples are not directly exposed to LN₂. Therefore, while immersion in LN₂ is commonly favored for long-term preservation, the adoption of vapor-phase cryogenic freezers offers enhanced safety and reduced risk of contamination and sample loss.1,2 For more information regarding the benefits of vapor-phase storage compared with liquid-phase storage.

Challenges in Selecting High-Quality Cryogenic Freezers

When evaluating the purchase of a cryogenic freezer, you may encounter several challenges, including the paradox of over-choice and the potential pitfalls associated with opting for cheaper, low-quality freezers.

The paradox of over-choice occurs when an abundance of options leads to decision paralysis, making it harder to choose the most suitable freezer. With a wide range of models, features, and specifications available, navigating the cryogenic freezer market can be overwhelming, complicating the selection process for your specific requirements.

Compounding this problem is the allure of relatively inexpensive cryogenic freezers, which can present a false economy. Despite their initial affordability, these budget-friendly options often sacrifice quality, reliability, and the comprehensive support needed for extended use. Moreover, they may have shorter lifespans, inferior warranties, and limited shipping choices, ultimately leading to higher total ownership costs in the long run.

• Exceptional Quality: From the selection of premium materials to the rigorous quality control processes, Air Products gives customers confidence in the durability, longevity, and superior functionality of our cryogenic freezers.
• Cost efficiency: Despite the initial purchase price of the unit being lower than other freezer types, the running costs associated with the upkeep and energy consumption of mechanical freezers can add up quickly. In addition, mechanical freezers generate significant amounts of heat, meaning that HVAC (heating, ventilation, and air conditioning) and temperature monitoring systems are required to limit heat access within the storage lab which results in additionaloperating costs.
• Industry Leading Warranties: Setting a benchmark for assurance and reliability, Air Products offers extensive warranty coverage on all cryogenic freezers. For instance, our MVE stainless steel cryogenic freezers boast an industry-leading 5-year vacuum warranty, underscoring Air Products’ commitment to producing high-quality units that are built to last, minimizing the risk of costly repairs or replacements down the line.³
• Customisable Storage Capacity: Catering to diverse storage needs ranging from vials to blood bags, Air Products gives customers the flexibility to customize storage capacity based on their specific requirements.
• Reliable Logistics: With over 75 years of experience in gas production and delivery, Air Products boasts a robust infrastructure and dedicated team of drivers, ensuring prompt and reliable delivery of freezers and gas supplies.
• Dedicated Customer Service: Customers can rely on Air Products’ industry-leading safety record and round-the-clock availability for deliveries and support, whether for routine equipment inquiries or urgent supply situations. The convenience of 24/7 access to customer service representatives for assistance with deliveries, equipment, and regulatory compliance cements Air Products’ reputation as a provider of world-class cryogenic solutions.⁴

Air Products: An Investment in Excellence

Navigating the landscape of cryogenic freezers can be challenging. While cheaper units may be tempting, the potential risks and hidden costs associated with low-quality freezers often outweigh the initial savings. Air Products’ range of high-quality MVE cryogenic freezers offers a solution to this dilemma, providing exceptional quality, industry-leading warranties, customizable storage capacities, reliable logistics, and a dedicated customer service team.
