For many protocols, 50 mL isn’t a need. It’s a habit; you grab it because it’s what’s on the shelf. The same is true for 15 mL tubes. And many users don’t realise that there’s an alternative, or what they could gain by switching.
For intermediate volumes, here are 5 reasons that Eppendorf 25 mL conical tubes could suit your lab better.
1. Better sample recovery, reduced risk of contamination.
How much of your sample can you remove without touching the inner wall of the tube? With a lower tube and a wide opening, it’s easier to reach your pipette in and get the very last drops.
If you’d like to review real data, check out this application note where you can review bacterial culture productivity and DNA yields using 25 mL tubes, compared to standard 15 mL conical tubes.
2. Half the volume. More plastic saved.
Used one at a time, they may seem like a small decision. But every 25 mL tube you use instead of a 50 mL tube means plastic saved. Across a busy laboratory, each choice that you make quickly adds up—and so does the opportunity to make a difference.
3. Fit more samples into busy freezers.
Using 25 mL tubes, 33% more can be stored in a standard freezer1. That’s because they’re lower in height compared to a standard 50 mL tube. If the same number of tubes can fit into a 3.5-inch freezer box compared to a 5-inch freezer box, your storage efficiency is basic math.
4. BioBased yet surprisingly affordable.
The 25 mL tube comes in a biobased variant—and Eppendorf is the only company to offer this solution. Book a BioBased consumables demo to ask about the quality, purity and technical performance; the entire biobased range is designed to meet the same specifications and performance requirements as comparable fossil-based materials.
If you’re not convinced by the quality or by environmental benefits, what about considering the costs? Eppendorf 50 mL fossil-sourced conical tubes are slightly more expensive than Eppendorf 25 mL biobased conical tubes, so you can ‘save’ in multiple different ways.
5. Use your existing lab equipment.
Good news: no new rotor needed. 25 mL tubes fit with a simple adapter, so you can use your existing centrifuge rotors and ThermoMixer without changing your workflow.
Eppendorf tubes are some of the best on the market for reducing leaks, designed for mixing, transport and centrifugation, and these 25 mL conical tubes meet the same high standard.
Try it for yourself. Contact Eppendorf to request a sample* and test how 25mL conical tubes can make a difference in your lab.
