Goated H20

Overview

Goated H20 is sterile water containing benzyl alcohol as a preservative, supplied in a sealed multi-dose vial. The preservative is the entire point of it: it is what allows a vial to be entered more than once without the contents turning into a growth medium, which is why this is the standard diluent for reconstituting lyophilised research peptides where a single vial will be drawn from repeatedly over a series of experiments. Sterile water without preservative is suitable only for a single entry. The benzyl alcohol concentration for the lot supplied is stated on its documentation and should be recorded, because it forms part of the composition of every working solution prepared with it.

Laboratory uses

The points below set out what this item is used for in a laboratory setting. They describe handling applications only and represent no outcome of any kind.

• Reconstitution of lyophilised research peptides for laboratory use
• Preparation of working solutions where a vial will be entered more than once
• Dilution of stock solutions within a research protocol
• Compatibility and stability testing of peptides against a preserved diluent

Specifications

Handling and storage

• Store at controlled room temperature unless the lot documentation states otherwise. Protect from light and do not freeze.
• Inspect the vial before each entry. Set it aside if the solution is discoloured, cloudy or contains particulate matter.
• Use aseptic technique and a fresh needle for each withdrawal. Do not return withdrawn material to the vial.
• Record the date of first entry on the vial and establish an in-use period from your own assessment rather than from a supplier figure.
• Use standard personal protective equipment and handle in an appropriate laboratory setting.

Lot documentation

Each lot is supplied with its own documentation stating the specification that applies to it. Concentrations and any preservative content should be read from that document and recorded against any protocol this item is used in, since those figures determine the composition of the working solution it is used to prepare.
