Vetter dual-chamber systems

Vetter dual-chamber systems

Vetter’s special dual-chamber technology offers a patented, innovative delivery method for liquid and lyophilized drugs that require mixing immediately prior to application.

The dual-chamber design allows different ingredients and solvents to be prefilled and stored separately, then easily mixed and administered as needed.

There are 2 dual-chamber systems to choose from:

  • Vetter Lyo-Ject® dual-chamber syringe
Vetter Lyo-Ject® dual-chamber syringe

1.0 ml, 2.5 ml, and 5.0 ml formats

  • Vetter V-LK® dual-chamber cartridge
V-LK® dual-chamber cartridge

1.0 ml format

Both systems offer multiple advantages for your sensitive injectable compound, including

  • simple administration - fewer steps are required for preparation and injection when compared to traditional vial/syringe combinations, with no need for multiple needles or transfers devices
  • increased patient safety - the all-in-one design allows precise dosing and helps to minimize reconstitution errors
  • high product security - all dual-chamber systems are closed inside the lyophilizer at the end of the lyo process
  • versatility - dual-chamber cartridges are designed for use with both single- and multidose applications in pens
  • low residual volume - closure system and stopper geometry allows little product loss, reduce overfill, and minimize packaging waste
  • market differentiation - dual-chamber technology gives your compound a unique edge over competitive products
