) PREVENTIVE MAINTENANCE
The MVE CryoCube is designed as a limited use product and should
be considered a disposable shipper. Generally, no preventive
maintenance is required for the CryoCube. However, if the unit
performance drops below an acceptable hold time (< 5 day holding
time @ >-150C), users should contact Chart Inc. Customer/Technical
Service for rework options. The rework options may extend the
overall life of the unit.

) SHIPPING INSTRUCTIONS

ollow charging instructions. Prior to packaging dewar for shipment
the entire contents of liquid nitrogen must be removed. This is
usually done by pouring out excess liquid nitrogen until no liquid is
visible on the bottom of the inner dewar. Place in bio samples,
package dewar and ship. If liquid nitrogen is visible in the bottom of
the inner it then becomes a liquid shipper and the exception status is
void. The liquid inside is now classified as hazardous material.
LETTER EXPLAINING EXCEPTION
This is concerning the applicability of the Federal Hazardous Material
Regulations to the shipment of refrigerated samples in the “Dry
Shipper” container. A “Dry Shipper” package consists of an outer
container that is lined with an absorbent material. The container is
charged with nitrogen refrigerated liquid which is absorbed into the
container lining. The charged, completed package serves as
refrigerated container for the shipment of samples.
In consideration of the above, consultation with the Research and
Special Programs Administration of the DOT has determined that the
use of nitrogen refrigerated liquid charged “dry shipper” containers
for the shipment of samples fall within the regulation exception
provided in 49CFR 173.320 paragraph (a) of the section states the
r
equirements of this subchapter do not apply to atmospheric gases
