°Cs Collapsible Air Reduction Accordion Storage Bottle

$6 ~~$14.99~~ In stock

Collapsible bottle for photographic chemicals. Heat conductive material keeps chemistry at the correct temperature with the TCS-1000 "Temperature Control System". Opaque plastic designed for storing darkroom chemistries that are sensitive to light and air. Accordion-like bottle with screw-on cap can be compressed allowing the volume of the bottle to be adapted to match the amount of liquid in it, which reduces the risk of oxidation. Chemicals stored in the bottle last longer when compared to conventional bottles.

Finally a bottle that keeps my developer at the right temp without me babysitting it on the counter—the heat-conductive walls actually hold the TCS-1000's setting nicely. The accordion design squeezes down flat when I'm done, which frees up half my darkroom shelf.

The accordion pleats actually collapse down flat as I drain the last of the developer, so there's barely any air left to oxidize the chemistry. The opaque plastic blocks light completely, and the heat-conductive body holds my working solution right at 68°F for the whole session without fiddling with
