This question comes up constantly in labs. 2 mL vial labeling sounds simple, but in practice it’s one of the most failure-prone parts of sample handling — not because the vial fails, but because the label does.

We recently broke this down in detail here:
👉 How to Label a 2 mL Vial (and Why Adhesive Labels Fail)
https://tubewriter.com/how-to-label-2ml-vial/

Below is the short, practical version for anyone dealing with this daily.

Why do labels keep falling off 2 mL vials?

Most cases of labels falling off vials come from the same set of issues:

• 🧊 Adhesives fail in cold storage, especially −

Every year, many research and diagnostic labs face the same challenge — how to use the remaining CapEx (capital expenditure) budget wisely before it expires.

We recently published a guide on this topic:
👉 The Smart Way to Spend Your Lab’s End-of-Year CapEx Budget

The goal isn’t just to “use it or lose it.” It’s to invest in upgrades that compound efficiency, accuracy, and reproducibility for the next fiscal year.

we recently made a big change in our lab that’s been a game-changer for accuracy and efficiency: switching to direct microplate labeling.

If you’ve ever spent hours handwriting labels, dealing with peeling stickers, or trying to read smudged markings after a solvent rinse, you know how much time and data risk that creates. We didn’t realize how much it was holding us back until we automated the process.

Here’s why we strongly recommend making the switch:

✅ 1. It Practically Eliminates Labeling Errors

Direct labeling prints text, barcodes, or QR codes right onto the microplate surface — no adhesives, no handwriting. Every label is uniform and machine-readable, which means fe

If you’ve ever scrambled in the cold room trying to read faded labels, dealt with peeling stickers, or struggled to keep consistent labeling across your lab team—this just might be your new secret weapon.

I just came across a great write-up on introducing a direct tube labeling system in biological labs. It walks through why conventional methods (handwriting, adhesive labels) tend to fail in real lab environments, and how printing directly on tubes can dramatically improve sample identification, reproducibility, and workflow efficiency.

Some highlights:

• Traditional labels smudge, peel, or fade under freeze–thaw cycles, solvents, or ultra-low temps
• A tube printer prints direc

At TubeWriter, we’ve been diving deep into the challenges that CROs face when it comes to labeling. Manual stickers and handwriting may work at small scale, but at high volumes they create risks: sample mix-ups, compliance issues, and wasted time.

We recently published a blog on this topic: Why CROs Need Lab Automation Solutions for Smarter Labeling

Here are a few highlights:

• Reduce errors: Automation minimizes labeling mistakes across thousands of samples.
• Stay compliant: Permanent, legible labels help meet GLP, CLIA, and FDA traceability requirements.
• **Save ti

What is TubeWriter?

TubeWriter is a direct-printing system for laboratory sample identification. Instead of applying adhesive labels, it prints directly onto labware so marks stay put and workflows move faster.

What problems does it solve?

• Cold storage reliability: Adhesive labels can peel, smear, or fall off in cold or humid conditions. Direct print eliminates label failures.
• Throughput & labor: High-volume labeling is slow and error-prone. Direct printing speeds up batch work and reduces manual handling.
• Clarity & durability: Crisp, consistent text and barcodes improve readability and tracking.
