Reconstitution Syringe 5ml 21G (Pack of 1) – Lab Essential Overview
A Reconstitution Syringe 5ml 21G (Pack of 1) is a standard laboratory tool used for drawing, measuring, and transferring liquid volumes during reconstitution and research protocols. The 21G gauge offers a wider bore suited to drawing solution from vials, particularly where viscosity or volume makes a finer needle impractical. Each Reconstitution Syringe 5ml 21G (Pack of 1) is supplied sterile and individually packaged, for laboratory and research use only — not for human or veterinary use.
Pyrox Labs supplies the Reconstitution Syringe 5ml 21G (Pack of 1) as a lab essential alongside our full peptide research range, giving researchers a reliable, sterile option for measuring and transferring solution during reconstitution and experimental work.

Correct handling of the Reconstitution Syringe 5ml 21G (Pack of 1) follows standard laboratory safety protocols, including single-use disposal and appropriate sharps management. For further guidance on safe sharps handling and disposal in a laboratory setting, researchers can refer to the UK Health and Safety Executive’s guidance on needlestick and sharps safety.
Lab Applications
Within laboratory settings, a Reconstitution Syringe 5ml 21G (Pack of 1) is commonly used to draw bacteriostatic water or other diluent into a vial during peptide reconstitution, and to measure out solution accurately for downstream research use. The wider 21G bore makes it well suited to drawing larger volumes quickly compared with a finer-gauge insulin syringe.
Once reconstitution is complete, researchers typically switch to a finer-gauge syringe, such as our Insulin Syringe 0.5ml 29G (Pack of 10), for precise, low-volume measurement. The Reconstitution Syringe 5ml 21G (Pack of 1) is best suited to the initial reconstitution step rather than fine dosing measurement.
The Reconstitution Syringe 5ml 21G (Pack of 1) is commonly used alongside our Bacteriostatic Water 3ml or Bacteriostatic Water 10ml, and Leukoplast Pre-Injection Wipes (Pack of 20) for vial-top disinfection. For step-by-step guidance on the full process, see our How to Reconstitute Peptides guide.
Storage Guidance
- Store in a clean, dry place at room temperature
- Keep in original, unopened packaging until ready for use
- Do not use if the sterile seal has been broken or compromised
- Check the printed expiry date before use
- Single-use only; do not reuse or re-sterilise
Frequently Asked Questions
What is Reconstitution Syringe 5ml 21G (Pack of 1) used for?
It’s a laboratory consumable used to draw, measure, and transfer liquid volumes during peptide reconstitution and other research protocols.
Why use a 21G needle instead of a finer gauge?
The wider 21G bore makes it easier to draw larger volumes of diluent quickly, particularly where viscosity would make a finer needle impractical. Once reconstituted, researchers often switch to a finer-gauge syringe for precise dosing measurement.
How is Reconstitution Syringe 5ml 21G (Pack of 1) supplied?
As a single sterile, individually packaged syringe with a 5ml capacity and 21G needle.
Are these syringes reusable?
No. Each Reconstitution Syringe 5ml 21G (Pack of 1) is intended for single use only and should be disposed of appropriately after use in a sharps container.
