LN2 Dewars Guide at a Glance
Each of IC Biomedical’s six LN2 dewar models features a rugged ribbed aluminum construction, magneformed necktube design, vacuum insulation and ISO 13485 certification. Take a closer look at each model below.
Please note that the 25LD, 35LD and 50LD models also offer an optional liquid withdrawal device (LWD), enabling convenient, efficient dispensing of pressurized liquid nitrogen. With a flow rate of up to 8 liters per minute and an operational pressure of up to 7.25 psig (0.5 bar/50 kPa), this solution is ideal for high-speed environments where manual pressurization is insufficient.
Which LN2 Dewar Should I Buy for My Business?
If you’re still unsure of the best option for your needs, take a look at our recommendations based on some of the most common industry needs we see.
Research Laboratories: 10LD or 25LD
These models offer a balance between extended storage space and portability, making them ideal for active sample work and continuous dispensing.
Biobanks and Sample Repositories: 35LD or 50LD
These large containers come with equally long hold times with minimal refilling needs, allowing you to cut down on maintenance and store the most samples within the smallest footprint.
IVF, Reproductive Clinics and Dermatology Centers: 25LD or 35LD
Both of these models facilitate clinical excellence by meeting regulatory compliance guidelines for preserving sample integrity.
Artificial Insemination and Animal Husbandry Locations: 25LD or 35LD Plus Optional LWD
When your field requires off-season storage and pressurized dispensing, these powerful models provide extended hold times and precise semen handling.
Field and Portable Operations: 4LD or 5LD
Operations that regularly transport sensitive materials will benefit from these lightweight, easy-to-handle options.
