Vial or pen: choosing a format for your lab

Every NEXCELL research peptide comes as a vial or a pen, in single units or packs of 10. How the formats differ, and how to choose for your workflow.

Vial or pen: choosing a format for your lab – NEXCELL Journal

Each compound in the NEXCELL collection is available in two formats. Both carry the same batch identification and certificate of purity; what changes is how the material is supplied and handled in the lab.

Vials

The vial is the classic format: a lyophilised powder in a sealed glass vial, reconstituted in the lab with a measured volume of liquid. It suits workflows where you control the concentration yourself, need to prepare several dilutions, or already have SOPs built around vials.

  • Flexible: you choose the volume and concentration.
  • Long-standing format with well-established handling procedures.
  • Pair with bacteriostatic water in 3 mL or 10 mL.

Pens

The pen supplies the compound in a sealed, pre-prepared cartridge inside a labelled NEXCELL housing. It reduces preparation steps and keeps the batch label with the material at all times.

  • Fewer preparation steps before use in the lab.
  • Batch number and compound printed on the housing.
  • Consistent presentation across a series of experiments.
