Hi Simon and others,
For years we have been using Nalgene HDPE 30ml bottles for collecting 
water samples. They are "nearly" indestructible, big enough so that 
you can write on them (lat/lon river name, etc.), and they are 
lightweight. Because even a permanent marker will rub off in the 
field (bouncing around in a 4x4) we wrap clear packing tape over the 
marker and keep the cap on with electrical tape.

We observe no change in values over a period of years.
Hope this helps,
Bill
