What the AI looks for in Lab Tube Racks
- Tube outer diameter
- Choose the well size by the tube's outer diameter (common sizes are 13, 16, 20, 25 and 30 mm). The rack is defined by tube diameter, not volume.
- Material
- Use polypropylene for autoclaving and solvents; use epoxy-coated wire for heavy glass. It determines how long the rack lasts.
- Conical tubes
- 15 and 50 mL conical tubes need racks with deep wells or a support for the conical tip. Flat-bottom racks let conicals tip.
- Water baths
- For water-bath use, choose an open, drain-through design or a floating rack. Closed blocks trap water and float unpredictably.
Brands that matter
- Thermo Scientific Nalgene: Durable autoclavable polypropylene racks.
- Heathrow Scientific: Multi-size and conical tube racks.
- Bel-Art (SP Scienceware): Epoxy-coated wire and plastic racks.
- Globe Scientific: Budget plastic racks.
What to avoid
- Bare wire racks in wet or corrosive areas.
- Buying by tube volume without checking diameter.
