Twin Dose Syringe 0.05ml & 0.1ml


Kaycee Twin Dose Self-Refilling Syringe - for reliable twin injections in fish

Our Twinjector twin-dose syringe is specifically designed to deliver two vaccines of differing viscosity in a single dose through one needle. 

This is the culmination of significant research and development in response to the needs of the aquaculture industry, part of working closely with our customers and incorporating their feedback into the development of our products.

Comfortable to use, its ergonomic design minimises operator fatigue and maintains injection site accuracy.

Designed, manufactured and assembled in England to a high standard, these solid devices are easily serviceable as all components are available as spare parts. 



The Twinjector syringe features two independently adjustable doses of 0.05ml and 0.1ml. 

Dual 0.05ml, Dual 0.1ml, Combination 0.05ml and 0.1ml

The syringe can be used with all oil and water based vaccines and comes with our Fishguard needle guide to aid in the correct location of injection site and to help prevent needle stick. 

Fitted with two tube-feed connectors for easy connection to vaccine bags. 


Magnetic Counter

Our magnetic counter system, held in a clear acrylic case and sealed with a plastic cap and O-ring, provides an accurate count of the number of doses made for easy tracking of your team's efficiency and throughput.
