Globe Scientific ESR 10-Place Polystyrene Rack for Westergren Pipettes (3472)

Globe Scientific ESR 10-Place Polystyrene Rack (3472) holds up to 10 Westergren sedimentation pipettes for manual erythrocyte sedimentation rate testing. This rack is part of the Globe Scientific ESR system — a coordinated set of racks, leveling platforms, funnels, and transfer pipettes designed to work together for accurate, reproducible Westergren method ESR determinations.

Vertical Positioning for Accurate ESR Results

The Westergren method requires pipettes to stand perfectly vertical for the full 60-minute sedimentation period. Any tilt — even a few degrees — accelerates sedimentation on one side of the column and produces falsely elevated readings. This rack holds each pipette in a stable vertical position. For maximum accuracy, pair it with the Globe Scientific acrylic leveling platform (3459), which features a built-in bubble level and four adjustable feet to compensate for uneven benchtop surfaces. The rack-plus-platform combination eliminates the two most common sources of manual ESR error: tilted pipettes and unlevel surfaces.

3472 vs. 3452: Choosing the Right ESR Rack

Globe Scientific offers two ESR rack options. The 3452 features individual spring-loaded support clamps that independently grip each pipette — more secure, better for labs where racks are moved during the sedimentation period or where bench vibration is a concern. This rack (3472) is a simpler polystyrene holder without individual clamps — lighter, lower cost, and fully adequate for laboratories where the rack stays stationary on a level surface for the duration of the test. Both models hold 10 pipettes in the vertical orientation required by the Westergren method.
