I have a client that is trying to store their DS in the same container that it is stored in the warehouse. They are having trouble locating an HDPE drum that is comparable. In my experience – as long as the HDPE bottle/drum is made of the same resin/colorant – they should be good to go. The drums in the warehouse use clamps to close the lids – the smaller versions they have been able to find are either screw cap or snap on. Is this a reasonable way to store the DS for stability studies?

In my experience, using smaller containers of the same makeup has been acceptable. A possible point of contention would be if they had justification that the closures presented similar barriers to moisture and that the miniature did not provide a much tighter seal.
