We are using Socorex Calibrex 520 to dispense NaCl solution in vials. This new 520 model is way more fragile than the previous 521 model.

The product is easy to use however, the small pin that holds the dispensing unit onto the bottle is not very durable, we have had to find replacements. Also, the dispensing unit is difficult to remove from the bottle at times.
