What is bacteriostatic water?<\/h2>\r\n  <p>\r\n  Bacteriostatic water is a sterile water specially formulated for the reconstitution of peptides in the laboratory.\r\n  It contains a very small amount of benzyl alcohol (0.9%) which prevents bacterial growth in the bottle after opening.\r\n  <\/p>\r\n  <p>\r\n  Unlike ordinary sterile water, bacteriostatic water enables reconstituted products to be stored longer\r\n and in complete safety, making it ideal for research solutions requiring multiple sampling.\r\n  <\/p>\r\n\r\n  <h2>2. Why is it used with peptides?<\/h2>\r\n  <p>\r\n  Peptides are supplied as lyophilized powder (dry powder). In order to be studied or manipulated in the laboratory,\r\n they must be reconstituted with suitable water. \r\n  <\/p>\r\n  <p>Bacteriostatic water enables :<\/p>\r\n  <ul>\r\n    <li>\r\n      <strong>Safe reconstitution<\/strong>: limits bacterial proliferation in the reconstituted solution.\r\n    <\/li>\r\n    <li>\r\n      <strong>Better storage<\/strong>: thanks to benzyl alcohol, the reconstituted mixture can be stored for several days\r\n in the fridge, unlike sterile water, which has to be used all at once.\r\n    <\/li>\r\n    <li>\r\n      <strong>Precise dosing<\/strong>: it facilitates handling and allows several samples to be taken from\r\n the same bottle without compromising sterility.\r\n    <\/li>\r\n  <\/ul>\r\n\r\n  <h2>3. How much to use?<\/h2>\r\n  <p>\r\n  The amount of water to add depends on the peptide and the desired concentration, but the general rule remains the same:\r\n  <\/p>\r\n  <ul>\r\n    <li>Gently add water along the side of the bottle.<\/li>\r\n    <li>Do not shake vigorously, but gently rotate the bottle between your fingers until the powder is completely dissolved.<\/li>\r\n  <\/ul>\r\n\r\n  <h2>4. Storage: how long?<\/h2>\r\n  <p>\r\n  Once reconstituted with bacteriostatic water, a peptide can generally be stored in the refrigerator for a period\r\n of around 20 to 30 days.\r\n  <\/p>\r\n  <ul>\r\n    <li>Refrigerated storage: generally 20 to 30 days.<\/li>\r\n    <li>Do not freeze the reconstituted solution.<\/li>\r\n    <li>Peptide powder (not reconstituted) should be stored in a cool, dry place, protected from light.<\/li>\r\n  <\/ul>\r\n  <p>\r\n  The exact duration may vary according to the studies available for each peptide. Use is strictly for research purposes. \r\n  <\/p>\r\n\r\n  <h2>5. Can bacteriostatic water be replaced by sterile water?<\/h2>\r\n  <p>\r\n  Sterile water can be used, but is not recommended if the bottle is to be used more than once.\r\n  <\/p>\r\n  <p>\r\n  In a nutshell:\r\n  <\/p>\r\n  <ul>\r\n    <li><strong>Sterile water<\/strong>: immediate, one-time use.<\/li>\r\n    <li><strong>Bacteriostatic water<\/strong>: prolonged use, with multiple sampling possible over time.<\/li>\r\n  <\/ul>\r\n  <p>\r\n  For this reason, bacteriostatic water is strongly recommended for the reconstitution of peptides used\r\n in multi-day research.\r\n  <\/p>\r\n\r\n  <h2>6. Why do some customers forget?<\/h2>\r\n  <p>\r\n  Bacteriostatic water is sold separately from the peptide, and many customers only realize at the time of reconstitution\r\n that they are lacking the necessary water.\r\n  <\/p>\r\n  <p>\r\n  To avoid this oversight, we recommend that you always check that you have :\r\n  <\/p>\r\n  <ul>\r\n    <li>Peptide vial(s).<\/li>\r\n    <li>Bacteriostatic water for reconstitution.<\/li>\r\n    <li>Handling equipment adapted to your research protocol.<\/li>\r\n  <\/ul>\r\n\r\n  <h2>7. Where to buy bacteriostatic water<\/h2>\r\n  <p>\r\n  You can obtain your bacteriostatic water directly from our website:\r\n <a href=\"https:\/\/peptivialab.com\/en\/produit\/bacteriostatic-water-pfizer-30-ml-multi-dose-vial\/\" style=\"font-weight: bold; color: #0073e6;\">\r\n Bacteriostatic water 30 ml - Peptivia Lab\r\n<\/a>\r\n    <\/a> .\r\n  <\/p>\r\n  <p>\r\n  By adding bacteriostatic water to your order at the same time as your peptides, you can be sure of having everything you need\r\n to reconstitute according to your research protocol.\r\n  <\/p>\r\n<\/article>\r\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Bacteriostatic water: why is it essential for your peptides? 1.
