4. Pour off excess liquid just prior to shipment.
a. If necessary to completely dispense all liquid nitrogen, invert the unit until liquid nitrogen
dripping has stopped, set the unit upright and view if any liquid nitrogen pools at the
bottom of the unit. If liquid nitrogen starts to pool, invert the unit again. Repeat as
necessary until all liquid nitrogen is removed from the unit, in accordance with ICAO
Packaging Instruction 202. This process may take a few minutes.
5. Weigh unit and record.
a. To ensure a proper charging process is conducted, obtain both empty and charged
weights. Verify the differential between empty and charged weights is close to data in
Table 1. The differential can be calculated by using Equation 1.
Differential = Charged Weight — Empty Weight
b. Please note that the Charged Weight is not an indication of unit performance.
6. Place inventories into unit, replace cork/cover and lid.
UTILIZING THE QWICK CHARGE TECHNOLOGY
Only units bearing QWICK charge label is equipped with QWICK charge technology. To utilize the
QWick Charge Technology and charge in under 2 hours, do not allow unit to warm up above -150°C
between shipments. If the inside of the unit is above -150°C, it will need to be charged again for a
minimal of 24 hours to allow the unit to reach thermal equilibrium.
Use the following weight table as a general guide to determine if your vapor shipper is fully charged.
Values are for reference only. Weights can vary depending on the charging process. Refer to the
Static hold time and NER specifications listed in the table blow. Factors such as age of unit, quantity
of inventory, ambient environment, shipping condition, and use of accessories, etc. can negatively
affect unit Hold time and NER. If you do not find your model listed here, refer to the MVE
Cryopreservation Catalog or contact Customer or Technical Service for assistance.

MVE/Chart recommends the plastic protective shipping containers (PPSC) be used to help keep the
Vapor Shipper in the upright position and reduce the risk of damage to your valuable asset. DO NOT
SHIP UNIT ON ITS SIDE OR UPSIDE DOWN. SHIPPING THE UNIT IN ANY POSITION OTHER THAN
UPRIGHT COULD REDUCE THE HOLD TIME TO LESS THAN 10% OF STATIC HOLD TIME, AND CAUSE
PERMANENT DAMAGE TO THE UNIT AND LOSS OF INVENTORY. This could also void warranty.
Charge the unit by following all steps listed in OPERATION section before inserting into the PPSC. To
avoid damage to either the Vapor Shipper or PPSC never fill or dump the unit when inside the PPSC.
Fasten all locking latches tightly before shipping. You can also utilize cable tie, tamper proof security
seal, or any other appropriate secondary locking mechanism around existing locking latches to avoid
your asset from being tampered during shipment. Before putting PPSC into service, inspect it for any
damage that may jeopardize its functionality. Replace any aged/worn-out impact absorption foam
cushion inside the PPSC or any defective hardware. Remove badly damaged PPSCs from service.
Contact Customer or Technical Service for assistance in selecting the proper service parts.
MVE Vapor Shippers were primarily designed as vapor shipping containers, however, they can also
be used for immersion of samples. It is imperative that all liquid nitrogen be removed so the unit
remains classified as a Vapor Shipper for transport. 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.
Do not use any petroleum based cleaning solution.
Inside of the vessel:
Any cleaning solution that does not react with aluminum, stainless steel, or G10 composite can be used
in the sanitation process of a MVE Vapor Shipper. In most cases, any household detergent or mild soap
solution is suitable. Other cleaners and disinfectants that can be used safely include hydrogen peroxide,
chlorine/water mixture, and denatured alcohol. The generally accepted practice of using 10% chlorine
L/Day
bleach with 90% water solution holds as the best method for decontamination. It is recommended that
0.19
the unit is filled to its full capacity with the cleaning solution mixture, agitated, and then thoroughly
rinsed. It is important that all surfaces being sanitized are thoroughly rinsed and that all cleaner solution
0.26
residues are removed after cleaning. Allow the unit to dry completely before putting into service. It is
0.20
suggested that the unit is inverted to drain and dry completely.
0.09
Outside of the vessel:
0.85
Use light dampened cloth of mild soap solution.
0.70

0.35
The owner may follow two methods of maintenance, Continuous and/or Annual.
0.84
For Continuous Maintenance (Recommended before each shipment):
0.20
Follow steps 1 - 3 under OPERATION section above but allow the unit with full liquid to stand
0.35
undisturbed for 2 hours. Verify no major frost or condensation on outside of unit. Frost or
condensation on the outside of unit would indicate either a weak or no vacuum. Inspect the cork and
0.17
cover for signs of damage that may affect NER and Hold Time. Inspect the outside of the tank for
0.35
signs of shipping damage, such as large dents, especially around the neck tube area. Remove badly
0.10
damaged tanks from service.
0.35
Clean up any stain, contamination or condensation on the bottom of the unit after dumping liquid
0.20
out. Keep the unit in a cool, clean, and dry location for storage. These procedures can help prevent
0.40
corrosion on the bottom of the Vapor Shipper.
