Heathrow Scientific Polystyrene Tube Rack 50mL 1-Well Friction-Fit - Pack of 5

Single-tube racks are the most compact tube-holding solution for benchtop and biosafety cabinet use: one tube, one position, no wasted rack footprint. The Heathrow Scientific HS23053A Polystyrene Friction-Fit Tube Rack is a 1-well disc-format rack that holds one 50 mL conical tube per unit in a 3.6-inch circular footprint.

Supplied as a Pack of 5 blue polystyrene units — useful as individual tube holders at reagent preparation stations, on BSC work surfaces, or alongside other single-tube manipulation instruments. Friction-fit means the tube is held securely without clips or separate retention hardware.

Features and Benefits

• Single-Well Friction Fit: The 29 mm well holds one 50 mL conical tube securely by friction — no clips or separate hardware to add or lose.

• Compact 3.6 in Disc Format: Minimal bench footprint — sits alongside equipment, pipettes, and other tools without occupying rack-sized space.

• Pack of 5: Five units per pack — position one at each reagent station, biosafety cabinet position, or instrument port as needed.

• Polystyrene Construction: Low-density, lightweight material — not autoclavable, designed for single-use or light-duty bench use where autoclaving is not required.

• Blue Color: Visible against benchtop and biosafety cabinet surfaces — reduces the risk of missing a tube or knocking over an unnoticed rack.

Specifications

Laboratory Applications

• Reagent prep stations where a single 50 mL tube needs a stable position during pipetting without occupying a full multi-tube rack

• Biosafety cabinet single-tube use where minimal rack footprint is required and only one tube needs to be held at a time

• Equipment-side tube positioning — hold a 50 mL tube adjacent to a centrifuge, vortex, or pipette rack without using a full multi-position rack

• Temporary tube parking during multi-step manual workflows where tubes are moved between positions one at a time

Frequently Asked Questions

Is the polystyrene friction-fit rack autoclavable?
No — polystyrene is not autoclave-compatible. For autoclavable single-tube 50 mL racks, see the HS23051 1-Well Wire Tube Rack (HDPE coated steel, autoclavable).

Does this hold the tube at an angle or upright?
The disc well holds the 50 mL tube upright and vertical — the conical bottom of the tube extends below the rack disc while the tube body is supported by the 29 mm well walls.

Can this hold 15 mL conical tubes?
No — the 29 mm well is sized for 50 mL conicals. A 15 mL tube (approximately 16 mm OD) would pass through the well. For 15 mL or mixed-size single-tube use, see the HS23051 Wire Rack.

Quality Assurance

Heathrow Scientific HS23053A polystyrene tube racks are manufactured for single-use and light-duty bench applications. Friction-fit is verified against standard 50 mL conical tube outer diameters before shipment.
