Product

We’ve built eBac around one product:
30 mL sterile bacteriostatic water (0.9%
benzyl alcohol), filled in controlled lots
so you get the same clean, consistent
vial every time.

Bacteriostatic water is sterile water with
benzyl alcohol, used as a preservative
and solvent with antibacterial properties
for research dilution and reconstitution.

eBac Water is labeled and sold for
research use only.

Our goal is to keep this product continuously
available. We maintain inventory so orders
ship from a current tested lot. If we ever
expect a disruption, we’ll note it clearly at
checkout.

Ordering & Shipping

Once payment is confirmed, orders are
queued for packing and shipment from our
current released lot. We work to dispatch
orders promptly, though exact timing can
vary with workload and carrier schedules.

Vials are shipped in protective, discreet packaging to help prevent damage in transit.

We currently only ship within the
United States.

Yes. Once your order ships, you’ll receive an
email with tracking details so you can follow
the shipment to your location.

COAs & Testing

Visit our COA Library page. We display the
current shipping lot’s COA, and the lot code
on your vial label should match the lot code
shown there.

Lots change over time, but the product
stays the same. To keep things simple and
avoid confusion, we show only the current
production lot’s COA instead of listing
multiple past lots.

Each production lot is checked for
endotoxins, sterility, pH, and benzyl
alcohol concentration before release.
The COA summarizes these results.

Use & Safety

While we offer general sterile solution guidance regarding our product, we
cannot provide specific
dosing, protocol,
or medical instructions. Please follow
your internal procedures and consult
qualified
professionals.

Store the product according to the
conditions on the label, protected from
extreme temperatures, direct sunlight,
and contamination. Do not use vials that
are damaged, discolored, or past the
labeled expiry date.

Multi-dose vials are not meant to be kept
indefinitely once they’re opened. National
guidance for multi-dose vials generally
recommends dating the vial at first puncture
and discarding it within 28 days, unless the
manufacturer specifies a different period.

After that point, sterility can no longer be
assumed—there is effectively no “zero-
bacteria” guarantee beyond the 28-day
window.
