Fifty Vials, One Paperback-Sized Box: The Layout That Fits Fridge, Freezer and Bag
19.7 by 12.1 by 5.1 centimetres, priced at $39.99
The 50-Vial Peptide Storage Box measures 19.7 by 12.1 by 5.1 centimetres, roughly the footprint of a paperback novel but slightly thicker. It sells for $39.99 at Sydney Bacwater.
That size matters because it sets the limits of where the box can go. It slides into a door shelf, sits flat on a fridge rack, or drops into the outer pocket of most gym or work bags without needing to be repacked.
Fifty slots, each sized for a standard 3mL vial
The box holds up to 50 standard 3mL vials. Each slot is moulded to that vial diameter, so vials sit upright rather than rolling around when the box is tilted.
Fifty slots in this footprint means the internal layout is dense: rows are packed close, with just enough clearance between vials to lift one out without disturbing its neighbours.
3D-printed PLA construction
The box is made from 3D-printed PLA, a rigid plastic commonly used in additive manufacturing. This construction method allows the fifty individual slots to be produced with consistent wall thickness across the tray.
PLA is a solid, non-flexible material at room and fridge temperature, which is part of why the vial slots keep their shape and don't loosen with repeated use.
Fridge and freezer safe, no extra wrapping needed
The box is rated fridge and freezer safe, so it can go straight from a benchtop into cold storage without a separate container or bag around it.
This also means the box can move between temperatures repeatedly, useful for anyone shuttling vials between a home fridge and a travel esky, without needing to check the box itself for damage each time.
Where it actually sits on a bench
On a standard lab or kitchen bench, the box's 19.7 by 12.1 centimetre base is small enough to leave room for other bench consumables like a bacteriostatic water bottle or a sharps container beside it.
Its 5.1 centimetre height means it stacks under most upper shelving without needing extra clearance, so it can stay in a fixed spot on a shelf rather than being moved every time the fridge is opened.
