Update:  There are two versions of inserts now.  The original size fits the 32oz thermos.  There is a shorter version for the 18oz Hydrapeak food jar.

I designed a custom insert capable of securely holding 20 vials, with the option to hold two inserts in the 32 oz version, allowing for storage of 40 vials. These inserts are specifically engineered to fit seamlessly into both the 18 oz and 32 oz food thermoses made by Hydrapeak. The thermos provides robust protection against frost and moisture, ensuring the vials are preserved under various conditions. This practical and efficient solution is ideal for transporting and storing vials in environments where temperature and moisture control are critical.
