For research labs that want a dependable backup on hand, Renew Lab Group’s 50mL Bacteriostatic Water 2-Pack provides two independently sealed, batch-tested vials at a lower per-unit cost than ordering single vials separately. Keeping a spare vial in reserve is a common practice for researchers running continuous reconstitution protocols, since it eliminates the risk of a study pausing mid-run if a vial is dropped, contaminated, or simply runs low sooner than expected. Both vials in this pack are produced at our Houston, Texas facility and preserved with 0.9% benzyl alcohol to support multiple sterile withdrawals over time.
✔ Two 50mL vials per order ✔ USP-grade water for injection ✔ 0.9% benzyl alcohol preservative ✔ Independent batch-specific Certificates of Analysis ✔ HPLC and endotoxin tested ✔ Manufactured in a CLIA-certified Houston facility
Because each vial is tracked to its own production batch, you receive full documentation for both vials in your order rather than a single blended specification sheet. This makes the 2-Pack a practical choice for labs that want redundancy without the shelf-space or budget commitment of a larger multi-pack.
Why Researchers Choose Renew Lab Group Bacteriostatic Water
Consistency is the foundation of reliable reconstitution work, and Renew Lab Group controls every step of manufacturing in-house — from water purification through sterile filtration and final vial filling — to keep pH, osmolarity, and preservative concentration stable across every batch we release. Ordering vials in pairs is a popular option among independent researchers and small labs who want a ready backup without paying for a larger case they may not use before their study concludes. Each vial’s rubber stopper is designed to tolerate repeated needle punctures while maintaining a reliable seal, helping protect the unused contents between draws.
Reconstitution Guidance for Research Use
This product is intended strictly for laboratory and research applications and is not manufactured, labeled, or intended for human or animal administration. Standard aseptic technique should be followed for every withdrawal: swab the stopper with an alcohol prep pad, use a new sterile syringe and needle for each draw, and direct the stream slowly against the interior vial wall to avoid excess foaming or agitation of any lyophilized material being reconstituted. Once a vial is punctured, refrigerate it and use within the timeframe set by your institution’s protocols, since the benzyl alcohol preservative slows, but does not eliminate, microbial growth after the seal is broken.

What’s Included
Your order includes two 50mL vials of Renew Lab Group Bacteriostatic Water, each sealed with a tamper-evident aluminum cap and rubber stopper, plus digital access to the batch-specific Certificate of Analysis for each lot represented in your order. Vials are packed together with protective materials to prevent breakage in transit and typically ship same-day from our Houston facility.
Shipping & Storage
Store both vials at room temperature prior to opening, away from direct sunlight. Once a vial is punctured, refrigerate it between uses to help preserve product integrity. Orders ship from Houston, Texas via trackable carrier service, packaged to protect glass vials from impact and temperature swings during transit.
Frequently Asked Questions
Is this product intended for human use?
No. This product is sold strictly for laboratory research purposes and is not intended for human or veterinary administration.
Do both vials come from the same production batch?
Not necessarily — vials may be drawn from different batches depending on inventory. Each vial’s Certificate of Analysis reflects its own specific lot.
Why order two vials instead of one?
A second vial gives your lab a ready backup, reducing the risk of a study being interrupted due to breakage, contamination, or running low unexpectedly.
What is the shelf life after first use?
Once opened, refrigerate and use within the timeframe outlined by your lab’s internal protocols, as preservative effectiveness diminishes over time.
Can I order a larger multi-pack instead?
Yes, this product is also available in 1-Pack, 5-Pack, and 10-Pack configurations to match your lab’s usage volume.
Where is this product manufactured?
All Renew Lab Group Bacteriostatic Water is produced at our CLIA-certified facility in Houston, Texas.
For laboratory and research use only. Not for human or animal use. Not for injection into humans. Not a drug, food, or cosmetic product.
