Technical Narrative
The TrippNT 50570 Double HDPE Bottle Holder 500 mL provides two-position anti-tip bottle restraint in ¼″ white HDPE (high-density polyethylene) for environments where two 500 mL reagent bottles must be staged side by side at a single wall-mount or benchtop position under high-frequency bleach or aggressive disinfectant cleaning protocols. Two 3¾″ diameter circle-cut collar slots on a continuous rectangular walled base each engage a standard 500 mL bottle body below the shoulder, maintaining upright stability as the bottle depletes and becomes top-heavy. Pre-drilled keyhole slots on the rear panel accept standard #6 or #8 wall fasteners; the flat base allows benchtop placement without mounting hardware. At 7½″ W x 3⅛″ H x 4⅛″ D and 0.61 lb, the double footprint fits two bottles side-by-side within the 8″ wide zone typical of BSC interior rear staging and fume hood rear bottle positions.
The HDPE construction withstands routine cleaning with bleach, Sporicidin, peracetic acid, sani-wipes, and quaternary ammonium concentrations that degrade ABS over time. The HDPE 500 mL family scales to Single (50569), Triple (50571), and Quadruple (50539). Ships fully assembled. Backed by TrippNT’s 100% Lifetime Guarantee.

Frequently Asked Questions
When does the two-position HDPE 50570 make more sense than two individual Single HDPE 50569 holders at the same location?
The 50570 installs at a single keyhole pair, keeping both bottle positions level and aligned automatically on one continuous base, and costs less than two individual 50569 units at the same position count. Two individual 50569 holders require two separate keyhole installation points, two hardware sets, and two independent height-alignment decisions. Specify the 50570 for any permanent two-bottle position in the same horizontal plane; specify the individual 50569 only when the two bottles must be at different heights or on different wall surfaces.
Why does the HDPE 500mL holder cost more than the equivalent ABS 500mL holder, and is the price difference worth it for my environment?
HDPE has a higher raw material cost than ABS and a different machining behavior, contributing to a modestly higher per-unit price. The price difference is justified when site-specific cleaning chemistry will materially degrade ABS faster than the holder’s expected deployment life of 5–10 years. In environments using only 70% IPA or dilute QAC, ABS lasts the same deployment duration as HDPE and the lower-cost ABS double (50017) is the appropriate specification. In environments with validated bleach or peracetic acid cleaning SOPs, the HDPE pays back the price difference in avoided premature replacement cycles within 2–3 years.
