Choice of container is determined by two factors:

  • Storage capacity of semen in straws
    A larger neck diameter on the container is necessary for increased storage capacity. The containers are commonly used in European livestock breeding (medium/small) have a neck diameter that does not exceed 55mm. The new XT21 had a neck diameter of 55.4mm allowing for easier access.
  • Holding time of liquid nitrogen inside the container
    Holding time is chosen in relation to the minor or major difficulties of tracing liquid nitrogen. In the liquid nitrogen supply network in the UK is very good so for this reason 21 litre containers are most commonly used smaller flasks need to be refilled more often.

You can also choose from:

  • Single Layer – 5 canisters allows easy selection of straws e.g. 21XT5 Nitrogen Flask, 20 Litre with 6 x 38 x 127mm Canisters
  • Double layer – 10 canisters – storage only e.g. 21XT10 Nitrogen Flask, 20 Litre with 6 x 38 x 279mm Canisters
