Specifications

The Nalge Nunc Unitary Vented Safety Wash Bottles, Low-Density Polyethylene, NALGENE 2436-0506 500 Ml (16 oz.) Capacity, Pack of 4 come with a clear set of specifications designed for practical laboratory use. The primary material is low-density polyethylene (LDPE), chosen for its flexibility, chemical resistance, and durability. Each bottle has a capacity of 500 ml (16 oz.), an ideal size for most benchtop applications without being overly cumbersome.

The standout specification is the unitary vented safety system. This integrated design is crucial for handling volatile liquids, as it prevents pressure build-up within the bottle. This system ensures that when the bottle is squeezed, a strong, steady stream of liquid is dispensed, rather than an uncontrolled spray. For the specific 2436-0506 model reviewed, it is labeled for Sodium Hypochlorite (Bleach) and comes with a white HDPE 38mm closure. This color-coding system is a smart design choice to prevent cross-contamination, as different chemicals will be supplied with different colored caps, each featuring the corresponding chemical name and a color bar.

These specifications are not merely technical details; they translate directly into user experience. The 500 ml capacity is balanced, holding enough liquid for extended use without becoming too heavy or unwieldy. The LDPE material offers a good tactile feel, allowing for precise control over squeezing pressure. Most importantly, the vented closure is the game-changer, offering a level of safety and control that is essential when working with potentially hazardous substances like bleach.
