TrippNT Pipette Storage Bin 5 Compartment — Angled-Column PVC Wall and Hood Mount Bin for Serological Pipette Point-of-Use Staging
The TrippNT Pipette Storage Bin 5 Compartment (SKU 50428) is a vertical wall-mount and hood-mount serological pipette staging bin designed for environments where serological pipettes are consumed at high daily rates directly from the point-of-use position — BSL-2 and BSL-3 biosafety cabinets (BSCs), standard chemical fume hoods, laminar flow benches, and high-throughput cell culture and virology benches where reaching into a drawer for each pipette would break workflow rhythm. At 4½″ W × 27″ H × 10⅛″ D with five angled compartments running from top to bottom, the 50428 holds up to five full-length serological pipette boxes (1mL through 50mL formats) in angled open-face slots that keep each pipette accessible for one-handed grab-and-use access without opening a box or searching a drawer. The angled-column geometry ensures the pipettes remain stable and angled toward the user, preventing forward sliding that would cause tip contact with the bin front surface.
Constructed from 1/4-inch white PVC, the 50428 mounts on any ferromagnetic steel surface (fume hood side panel, BSC exterior, stainless steel supply cart side) via keyhole wall mounting with included hardware. The open-column design allows pipettes to be removed and returned with a single hand while the other hand holds the culture flask, maintaining aseptic technique in BSL-2 environments where two-hand contact with shared surfaces is a contamination risk. Ships fully assembled. Also available in a clear acrylic version for environments requiring full visibility through the bin body. For a countertop/drawer horizontal pipette staging format instead of vertical wall staging, see the 50069 Large Pipette Storage Box Drawer Organizer (LS Batch 03).

Laboratory and Clinical Applications
The TrippNT 50428 is the standard specification for serological pipette point-of-use staging in: BSL-2 and BSL-3 biosafety cabinet side panel mounting (serological pipette staging within arm’s reach during cell culture, virology, and microbiology workflows), standard chemical fume hood side panels (serological pipette staging for titrations, reagent additions, and culture transfers), laminar flow and PCR clean bench staging (serological pipette staging maintaining clean zone discipline), core laboratory serological pipette staging (ELISA plate preparation, reagent transfer, sample aliquoting), tissue culture rooms (multi-flask serial transfer pipette staging), vaccine and biopharmaceutical manufacturing BSL-2 staging areas, food and beverage QA microbiology lab staging, clinical microbiology countertop or BSC staging (blood culture, microbial transfer staging), and research and teaching labs where frequent serological pipette access is required at the bench without accessing a drawer. Also used in fume hood surrounds for chemical titration pipette staging.

Frequently Asked Questions
What serological pipette sizes fit in the 50428 compartments?
The 50428 compartments are each approximately 1¾″ wide and 10″ deep, designed for standard serological pipette sleeve packaging in the 1mL through 50mL range. Standard serological pipette sleeves from major brands (Corning Costar, Thermo Stripette, BD Falcon, Sarstedt, Greiner Bio-One) in 1mL, 2mL, 5mL, 10mL, 25mL, and 50mL formats all fit in the angled columns in their sealed wrapper for single-pipette dispensing. For unusually wide-format serological packaging (some serological pipette brands use wider, stiffer wrappers) verify the sleeve width is under 1¾″ before ordering. The bin does not include retaining lips, relying on the angled column geometry to hold pipettes in place — the angle must face toward the user when installed for proper function.
Can the 50428 be placed on a countertop instead of wall-mounted?
Yes. The 50428 can be set on a flat bench surface in a freestanding configuration; the angled compartment geometry still functions correctly when the unit is placed flat, as the angle directs pipettes forward and upward toward the user. In freestanding mode the unit footprint is 4½″ wide × 10⅛″ deep, occupying a narrow bench strip that leaves most of the bench clear. For permanent hood or BSC side panel mounting, the keyhole mounting is the recommended configuration as it keeps the bench surface completely free.
