Phosphate buffered saline (PBS), 30mL vial

Description

Our phosphate buffered saline comes in a sealed 30mL vial with a rubber stopper, ready for use with peptides. It’s $19.99, and it’s in stock. Phosphate buffered saline (PBS) is a salt solution buffered with phosphate to hold a stable pH close to that of body fluids. It’s one of the most common solutions in biology labs.

You’ll need a reconstitution solution for every vial in our peptide vials and peptide blends ranges. It’s used to dilute peptides and to rinse or suspend cells without changing their environment.

What is phosphate buffered saline?

Phosphate buffered saline (PBS) is a salt solution buffered with phosphate to hold a stable pH close to that of body fluids. It’s one of the most common solutions in biology labs.

PBS is isotonic, which means it has roughly the same salt concentration as cells. That’s why it’s used when cells or tissues need to sit in a solution without swelling or shrinking.

How to use phosphate buffered saline for reconstitution

Wipe the stopper of both vials with an alcohol swab. Draw the volume you need with a sterile syringe, then let it run slowly down the inside wall of the peptide vial. Don’t squirt it straight onto the powder. Swirl gently until the solution is clear, and don’t shake it.

The volume you add sets the concentration. Adding 2mL to a 10mg peptide vial, for example, gives 5mg per mL. Write the volume and date on the peptide vial’s label.

Storage and shelf life

Keep the vial in the fridge and don’t freeze it. Once you’ve punctured the stopper, use a fresh sterile needle every time and never put a used needle back in. Throw the vial out if the liquid turns cloudy or has particles in it.

Common questions about phosphate buffered saline

Can PBS replace bacteriostatic water?

For single-use dilutions, yes. It has no preservative, so for vials you’ll draw from repeatedly, bacteriostatic water is the safer choice.

Does it need refrigerating?

Yes. Keep it in the fridge once it arrives, and don’t freeze it.

We also stock bacteriostatic water and acetic acid solution 0.6%, plus transfer pipettes for measuring small volumes. Browse all reconstitution solutions or the full lab supplies range.

Where the phosphate buffered saline fits in your workflow

A typical peptide workflow goes like this: wipe both stoppers, draw the solution with a sterile syringe, add it slowly to the peptide vial, swirl until clear, then label and refrigerate. Having the right solution on hand before the peptide arrives saves a trip and keeps freshly delivered vials from sitting around unmixed.

Tips for using the phosphate buffered saline

• Let a refrigerated vial come to room temperature for a few minutes before drawing, so the volume reads accurately.
• Keep a log of the date you first punctured each vial.
• Store it on a shelf away from the fridge door, where the temperature swings most.

Can I use it after the expiry date?

No. Once it’s past the date on the label, replace it.
