Very convenient for testing aquarium water!

I love this little rack. It takes half a dozen tubes to power my aquarium test kit so the size of this rack is perfect. Accommodates The only complaint is that the plastic is quite flexible, so pressing down to put the caps on the vials is a little awkward.

Pros
  • 2 x 1-1/16" (25mm) tube holders
Cons
  • Not sure

Check your tube size before ordering

For me it was a mistake. Totally my fault. Frame didn't fit my glasses. Drying sticks ok though if I don't tilt the rack the tubes will retain water while drying.This is not a problem as I don't require sterile sample tubes but make sure of your requirements before ordering.

Pros
  • 4 x 3/4" (20mm) tube holder
Cons
  • Not bad but...

Works well, wish the pins were longer.

I bought two of these pegs to constantly test while cycling in the aquarium. Suitable for API tubes but as the pins are short the tubes will not dry completely on the pins. You need to remove them and air the pens to allow the moisture remaining in the tubes to evaporate. If the pens were longer these things would be perfect for use in the aquarium.

Pros
  • 6 dry pegs
Cons
  • Damaged
