TrippNT Quadruple ABS Bottle Holder 1000 mL | HPLC Quaternary Fume Hood 4-Pos 50189

Technical Narrative

The TrippNT 50189 Quadruple ABS Bottle Holder, 1000 mL is the largest member of the 1000 mL bottle-restraint family, engineered for HPLC benches, extraction stations, and fume-hood solvent zones where four 1-liter mobile-phase or reagent bottles must be held side-by-side in a single wall-mount strip. Each of the four positions uses the same ⅛″ white ABS open-rectangular body and 3.75″ circular collar to create a two-point restraint — neck registered at the top, base captured in the open body — holding each bottle upright through vibration, fume-hood airflow, and incidental contact. Aligning four 1-liter bottles at consistent height and spacing supports HPLC quaternary mobile-phase sets (A/B/C/D) and paired solvent plus wash/rinse arrays on a single fixture.

External dimensions are 17½″ W x 4¼″ H x 4⅞″ D with a 0.6 lb finished weight. The 17½″ strip fits on standard 48″, 60″, and 72″ fume-hood side panels with margin. Wall-mount keyhole slots and mounting hardware are included. Ships fully assembled. Backed by TrippNT’s 100% Lifetime Guarantee. Scales within the same 1000 mL family to Single (50080), Double (50085), and Triple (50411); all share the same 3.75″ collar, 4¼″ H x 4⅞″ D profile, and keyhole mounting pattern.

Technical Specifications

Laboratory and Clinical Applications

The 50189 is deployed across regulated and research environments requiring four-position 1-liter bottle restraint, including HPLC quaternary mobile-phase staging, pharmaceutical QC and API synthesis fume hoods, biotechnology R&D extraction and purification solvent zones, USP 800 hazardous drug compounding hoods requiring four 1-liter bottle positions, environmental and water-quality testing HPLC mobile-phase stations, academic analytical chemistry and preparative HPLC fume hoods, forensic toxicology quaternary solvent staging, food-and-beverage R&D extraction benches, industrial QC multi-channel chromatography solvent management, and flammable-storage cabinet interior four-bottle restraint. Pairs with the single (50080), double (50085), and triple (50411) for mixed-channel installations using one hardware system.

Frequently Asked Questions

Is the 50189 suited for HPLC quaternary pump mobile-phase staging — do standard 1-liter HPLC solvent bottles fit all four positions?

Yes. The four 3.75″ collar positions accommodate standard 1-liter HPLC-grade glass and HDPE solvent bottles from Honeywell/Burdick & Jackson, Fisher Chemical, Sigma-Aldrich, and VWR, whose 1-liter neck profiles are consistent with the 3.75″ collar geometry. For quaternary gradient systems (A, B, C, D channels), the 50189 aligns all four mobile-phase bottles at uniform height with consistent tubing-adapter clearance. For binary HPLC (A/B), specify the double holder 50085 instead.

How does the 50189 four-position 1-liter strip compare to the 50157 four-position 500 mL strip — when do I use each?

Both are four-position ABS bottle-holder strips sharing the same keyhole mounting pattern and 4¼″ H profile. Specify the 50189 (17½″ W, 3.75″ collar) when using 1-liter HPLC mobile-phase or reagent bottles. Specify the 50157 (14⅞″ W, smaller collar) when using 500 mL bottles. The 50189 is 2⅝″ wider than the 50157 to accommodate the larger 1-liter bottle base diameter; both fit standard 48″ and larger fume-hood side panels.
