Both formats contain sterile water with 0.9% benzyl alcohol in 10 mL glass vials, with a COA for every lot. Here is how they compare:
| Product | Price | Price per vial | Price per mL |
|---|---|---|---|
| 10 mL vial | $14.97 | $14.97 | about $1.50 |
| 10 × 10 mL kit | $44.97 | about $4.50 | about $0.45 |
Prices as of November 2026; see the product page for the current price.
Buying ten single vials separately would cost $149.70, so the kit costs $104.73 less for the same 100 mL, roughly 70% less per vial. Browse both options in the reconstitution solution category.
Shipping cost in the US
Shipping to US addresses is a flat $15 per order. Orders of $100 or more ship free. Herbilabs ships to every US state. A few examples based on the prices above:
| Order | Products | Shipping | Total | Per vial, delivered |
|---|---|---|---|---|
| One 10 mL vial | $14.97 | $15.00 | $29.97 | $29.97 |
| One 10 × 10 mL kit | $44.97 | $15.00 | $59.97 | about $6.00 |
| Three 10 × 10 mL kits | $134.91 | Free | $134.91 | about $4.50 |
Because shipping is charged per order, the delivered price per vial drops quickly when you buy the kit or combine items to reach the $100 free-shipping threshold.
Single vial or kit: which is better value?
The single 10 mL vial makes sense if you need water for one batch of lyophilized material, want to try the product first, or are adding a vial to a larger order. The 10 × 10 mL kit is the better value if you work with reconstitution solution regularly: the price per vial is about $4.50 instead of $14.97, and every batch can start from a fresh, sealed vial instead of one that has already been opened.
Shipping also tips the balance. A single vial with US shipping costs $29.97 delivered, while a kit with shipping costs $59.97 for ten vials. If you order three kits, the order passes the $100 threshold and ships free.
What affects price when you compare suppliers
A low sticker price does not always mean a low cost. When comparing bacteriostatic water from different suppliers, look at:
- Volume per vial. Compare the price per mL, not just the price per vial. A cheaper vial that holds less water can cost more per mL.
- Lot documentation. Check whether there is a COA for every lot and whether you can read it before you buy. Herbilabs publishes its certificates on the COA page.
- Vial and stopper quality. A sealed glass vial with an intact stopper matters when material is drawn from the same vial more than once.
- Formulation. Confirm 0.9% benzyl alcohol on the label. Plain sterile water is a different product at a different price.
- Shipping. Add the shipping cost and check the free-shipping threshold. Shipping can double the cost of a single vial.
- Pack size. Multi-vial kits usually bring the price per vial down and let each batch of lyophilized material start from a fresh, sealed vial.
Planning how much you need helps you choose between one vial and the kit. The free reconstitution calculator works out water volume and the amount per draw for your material.
Wholesale pricing for larger volumes
Labs, teams and resellers that need more than a few kits can ask for wholesale pricing. Herbilabs supplies wholesale worldwide; send your expected volumes through the wholesale page or email info@herbilabs.com.
