Product Details

Parrox 0.9% Saline Solution — Compatible with Nebulizer Machines & Mesh Nebulizers | 50 x 5mL Single-Use Vials

 

Sterile. Simple. Effective.

 

When your nebulizer routine calls for standard isotonic saline, Parrox 0.9% sodium chloride delivers the most widely used concentration — clean, consistent, and nothing else. Just USP Grade sodium chloride at 0.9% and purified water. No preservatives, no additives, no fillers. Every 5 mL vial is single-use and individually sealed, so each dose is as sterile as the day it was made — no half-filled vials, no broken seals, no guesswork. 50 vials per box means you're stocked for the long run. Twist open, pour, nebulize, discard. That's it.

 

Beyond the nebulizer, the same sterile 0.9% saline is a dependable choice for general rinsing, irrigation, and laboratory/research use.

Key Benefits

  • USP Grade 0.9% sodium chloride — the standard isotonic concentration
  • Preservative-free — only sodium chloride and purified water
  • Individually sealed single-use vials — sterile every time, no leaking or half-filled vials
  • Compatible with standard nebulizer machines and mesh nebulizers
  • 50 vials per box — better value per vial
  • Lot # and expiry on every vial; made in a cGMP / FDA-registered facility
  • Versatile — nebulizer therapy, general rinsing/irrigation, and lab/research use

Ingredients USP Sodium Chloride 0.9% · Sterile Water (USP grade base)

How to Use

1. Twist or snap off the top of one sealed 5 mL vial.

2. Pour the contents into the nebulizer cup.

3. Attach the cup to the machine and run the session.

4. Discard the empty vial after use.

5. Rinse the nebulizer cup with clean water and allow to air dry.

Backed by Science. Trusted by Results.

At Parrox, our 0.9% Saline Solution is manufactured to the same standard your nebulizer routine depends on — isotonic, preservative-free, and sealed for single use. Every vial is filled with USP Grade sodium chloride and purified water, nothing more, so there's no guesswork about what's going into your device.

 

Every batch is produced in a cGMP / FDA-registered facility, with a lot number and expiry date on every vial — so you always know exactly what you're using and when it was made. Because each 5 mL vial is sealed individually, there's no risk of a half-used bottle losing sterility between sessions: every dose is as clean as the first.

 

✔️ USP Grade 0.9% sodium chloride — the standard isotonic concentration

Everything you need to know

How often can I use it?

0.9% saline is generally well tolerated; many routines use it every 4–6 hours. Always follow your prescription/device instructions and your healthcare provider's guidance.

Why 0.9% instead of 3% or 7%?

0.9% is isotonic — the same salt concentration as your body's fluids and the most common for everyday nebulizer use. 3%/7% are hypertonic; ask your provider if those fit your routine.

Is it compatible with mesh nebulizers?

Yes — it works with standard nebulizer machines and mesh nebulizers. Follow your device's cup-capacity instructions.

Can I save an opened vial for later?

No. These are single-use and preservative-free — once opened, sterility is broken. Discard any unused portion after each session.

Can I use it as a sinus or wound rinse?

Sterile 0.9% saline is commonly used for general rinsing and irrigation. For nasal/wound use, follow appropriate guidance; for eyes, use a product formulated for eye use. When in doubt, ask your provider.

Are the vials really sealed individually?

Yes. Every vial is individually sealed and marked with a lot number and expiry.

Any additives or preservatives?

None. Just USP Grade sodium chloride and purified water.

How should I store it?

Room temperature, away from direct sunlight and moisture. Don't use a vial that looks damaged, cloudy, or discolored.
