Lyophilized means freeze-dried. In lyophilization, a solution is first frozen. Water is then removed from it under vacuum without it becoming liquid again \u2013 it passes directly from the frozen to the gaseous state (sublimation). What remains is a dry powder or a compact powder cake at the bottom of the vial.<\/p>\n
Depending on the compound and fill quantity, the lyophilizate looks different \u2013 as a fine coating, a loose cake, or a small, compact disc. These differences are common with freeze-dried peptides.<\/p>\n
This dosage form is widespread in research because peptides are generally more stable in the dry state than in solution. This simplifies storage and transport. Further technical terms related to format and analytics are explained in the Glossary<\/a>.<\/p>\n Each vial is supplied together with the matching solvent so that the compound can be dissolved in the lab:<\/p>\n Bacteriostatic water is water with a preservative additive (benzyl alcohol). It is commonly used in laboratories to bring lyophilized peptides back into solution.<\/p>\n The strength \u2013 i.e., the amount of compound per vial \u2013 is stated on the respective product page. Some products offer several strengths; you can also see the available variants in the overview below.<\/p>\n Lyophilized compounds should be stored protected from light at \u221220 \u00b0C. After dissolution in the lab, the solution is kept refrigerated. Until use, the vial is best kept sealed in its packaging.<\/p>\n Note:<\/strong> The storage recommendation describes the handling of the compound as research material. All products are intended exclusively for research purposes \u2013 more on this under Research Use Only<\/a>.<\/p>\n<\/div>\n In addition to vials, SunPept also carries some compounds as a Pen. How the two formats differ and which format is more practical for which laboratory workflows is explained in the comparison Vial vs. Pen<\/a>. In the Shop<\/a> you can use the \u201cVials\u201d filter to show only this format.<\/p>\n The overview shows all products in vial format with prices. Clicking a product takes you to the product page with strengths and description.<\/p>\n\n Yes. Each vial comes with 1 \u00d7 bacteriostatic water (3 ml) for reconstitution in the lab.<\/p>\n<\/div>\n<\/details>","protected":false},"excerpt":{"rendered":" Was \u201elyophilisiert\u201c bedeutet Lyophilisiert hei\u00dft gefriergetrocknet.
