This advanced foldable fluid containment unit updates your photo processing hardware layout by introducing an opaque high-density bellows framework for light-sensitive liquid storage

Functional Features:
Actinic Ray Blocker Framework: Constructed with an opaque black pigmentation layer that completely repels active wavelength exposure, protecting development fluids from premature degradation
Volume-Adaptive Bellows Design: Compresses vertically to match the remaining liquid volume, expelling internal oxygen to minimize fluid oxidation without expanding the storage footprint
High-Density Polymer Casting: Manufactured from rigid HDPE substance that resists acidic and alkaline fluid erosion, maintaining operational structural integrity through repeated usage cycles
Integrated Labeling Panel Block: Features an embossed textured panel on the exterior body, allowing clear marking and identification of various development processing fluids
Anti-Volatilization Sealing Cap: Engineered with a tight-tolerance threaded closure that blocks fluid leakage and escape, maintaining fluid potency during prolonged darkroom placement

Specifications:
Component Base Substance: High-Density Polyethylene (HDPE) Base
Variable Unit Height Geometries: Approx 8-16cm (3.15-6.3 inches) Scalable Range
Preservation Intended Objective: Developed for Fixer Mixtures, Acid Baths, and Processing Fluids
Core Functional Attributes: Anti-Leaking Structure, Anti-Volatilization, Recyclable Layout
Package Option Tiers: Available in 1-Piece, 2-Piece, or 3-Piece Packs

Package Includes:
Package A: 1 x Piece Foldable Liquid Storage Unit
