These are the plain workhorse bottles — natural translucent, unlined polypropylene screw closure, nothing printed on them. They are lab bottle stock, which is why they are worth having in a vehicle: they hold up to solvents and fuels better than a kitchen container, they stack, and they cost little enough that you can keep a dozen sizes.

The big ones: a wide 100 mm mouth you can get a hand into, for bulk water, waste oil, washing-up water or dry bulk storage.

Read this before you buy: these two sizes are NOT leakproof. The manufacturer states it outright — “this bottle is not liquid leakproof.” The smaller wide mouth round bottles in the same family are guaranteed leakproof, which is exactly why this catches people out. Stand them upright, and do not lay one on its side in a vehicle.

And on the capacity: these are sold by the manufacturer as 2 L (0.5 gal). Two liters is 67.6 fluid ounces and four liters is 135 fluid ounces, so the “64 oz” in the trade name is nominal rather than exact.

What the manufacturer does and does not publish

This is lab-quality bottle stock — the same molding Nalgene supplies to laboratories, which is exactly why it is good for the field. Being honest about the data that comes with it: the manufacturer publishes the resin, the capacity, the closure size and the dimensions, and lists compliance with FDA 21 CFR 177.1520 and USP Class VI. It does not publish a country of origin, an upper temperature limit, or a BPA statement for this line. The BPA-free language you will see on Nalgene’s consumer bottles is a claim about those bottles, and we are not going to borrow it for this one. If any of those three points decides the purchase for you, ask us first and we will put the question to the supplier.
