In StockThis is bacteriostatic water, a sterile water-based diluent that contains a small amount of benzyl alcohol as a preservative. It is supplied in a 3 mL glass vial for laboratory use. It is a lab supply item, not a peptide or research compound itself.
Bacteriostatic water is a general-purpose laboratory supply used alongside peptide and protein research materials. It is not a peptide and has no compound class of its own. It has not itself been investigated as a research subject.
Store the sealed vial refrigerated and protected from light. Once opened, keep the vial tightly capped to limit contamination and return it to refrigeration promptly. Handle in a clean laboratory environment consistent with other liquid lab reagents.
Bacteriostatic water is used in laboratory settings to prepare working dilutions of lyophilized peptide material prior to in vitro or animal-model experiments, allowing researchers to standardize concentration across assay replicates. Its benzyl alcohol content inhibits microbial growth in the reconstituted solution, a property relevant to aseptic technique when a vial is accessed multiple times. Standard aseptic laboratory practice, including sterile syringes and a clean work surface, applies during dilution preparation.
All compounds are supplied for in-vitro laboratory research and identification purposes. For research use only.

Reconstitution Solution 3mL is a 3mL vial of bacteriostatic water with 0.9% benzyl alcohol, stocked by Core Research Peptides in the Lab Supplies category. It is a bench supply rather than a study compound, sized to put a single vial of lyophilized peptide into solution. The vial is priced at $9.00. Availability and dispatch: in stock and dispatched the same day, 7 days a week, on orders placed by 3 PM Central.
Quick answers
It is a 3mL vial of bacteriostatic water for the reconstitution of lyophilized peptides. The water dissolves the freeze-dried solid so the material sits in solution at a known concentration for benchtop study.
Both hold the same bacteriostatic water with 0.9% benzyl alcohol. The 3mL vial covers one vial of compound with less left over, and the 10mL vial covers several. The Size menu on the product page switches between the two.
It sells at $9.00 under SKU CRP-REC-3. Availability and dispatch: in stock and dispatched the same day, 7 days a week, on orders placed by 3 PM Central. Core Research Peptides is based in Austin, Texas and ships to US and international addresses.
3mL vial of bacteriostatic water with 0.9% benzyl alcohol, sized for reconstituting a single vial.
Bacteriostatic water for reconstitution of lyophilized peptides. 3mL vial, sterile water with 0.9% benzyl alcohol. The smaller size suits one vial of compound, with less left over once the work is done. For several vials, the 10mL size goes further.

Our compounds are tested by an independent third-party laboratory, and we publish the certificate for each one in our COA library. COAs are available on request and show HPLC and mass spectrometry data.
Each COA includes: compound identity confirmation, purity percentage via HPLC, mass spectrometry verification, batch number, and testing date. All testing is performed by an independent third-party laboratory. For research purposes only.
Lyophilized (freeze-dried) peptides should be stored at -20°C and kept away from light and moisture for maximum stability. Once reconstituted, store at 4°C and use within 30 days. All compounds are shipped with appropriate packaging to maintain integrity during transit. For laboratory research use only.
Orders placed by 3 PM Central are dispatched the same day, seven days a week. Every order ships from the US with tracked shipping, and your tracking number is emailed the day it ships. Most domestic orders arrive within 2–5 business days.
