Introduction
Once you've decided that BAC Water is the right solvent for your peptide reconstitution work, the next question is practical: what size vial do you need? Insulfine offers BAC Water in both 10 mL and 30 mL formats, each suited to different research workflows. Choosing the wrong size can mean wasted reagent, unnecessary cost, or running short mid-experiment.
This guide helps you match vial size to your actual lab needs.
The Core Difference
The volume difference is straightforward — but the implications for your workflow are not.
| 10 mL Vial | 30 mL Vial | |
|---|---|---|
| Total volume | 10 mL | 30 mL |
| Best for | Single peptide, short studies | Multiple peptides or longer studies |
| Waste risk | Lower (smaller commitment per vial) | Higher if not fully used |
| Cost per mL | Slightly higher | More economical |
| Ideal lab size | Individual researcher or small team | Core facility or high-throughput lab |
When to Choose 10 mL
10 mL vials are the right call when you:
- Are reconstituting a single peptide for a short-term study
- Work with small volumes per experiment (under 1–2 mL per draw)
- Want to minimize waste — especially when working with expensive or limited peptide stock
- Are evaluating a new peptide and don't yet know your consumption rate
- Prefer to open a fresh vial for each new experiment
The smaller format gives you more control over sterility and reduces the risk of contaminating a large volume of solvent.
When to Choose 30 mL
30 mL vials make more sense when you:
- Are running multiple reconstitutions from the same solvent batch
- Have a high-throughput protocol requiring frequent draws over several weeks
- Want to reduce the number of vials opened per project (fewer punctures = lower contamination risk per draw)
- Are managing lab costs across a team and need better per-mL value
The 30 mL format is particularly well-suited for core facilities or labs running parallel peptide studies simultaneously.
Thinking in Packs
Both sizes are available in multi-pack configurations — from 2-packs for getting started to 12-packs for ongoing research programs. A few rules of thumb:
- Estimate your monthly draw volume first. If you're drawing ~2 mL per week, a 10 mL vial lasts roughly a month — a 3-pack covers a quarter.
- Don't over-stock opened vials. BAC Water remains stable for 28+ days refrigerated, but unopened vials have a longer shelf life. Buy in packs that match your consumption rate.
- Mix sizes if needed. Some labs keep 10 mL vials for exploratory work and 30 mL vials for established protocols running in parallel.

Bottom Line
For most individual researchers, 10 mL vials offer the right balance of volume and sterility control. For labs running high-throughput or multi-peptide protocols, 30 mL vials deliver better value and fewer interruptions. When in doubt, start with a smaller pack to calibrate your consumption before committing to bulk quantities.
