micrometer syringe

A dilatometer using a micrometer syringe to measure small changes in volume at constant pressure is described.

Additionally, various micrometer syringes, immersion oils and microscopes are required for its use.

Solutions were introduced into the artery from micrometer syringes (200 ml volume) that connected to 'microfil' tubes.

A small amount (generally 1-2nL) of solution is pipetted or blown into the oil in the wells using a micrometer syringe or a pulled capillary tube.
