I am about to embark on a new project which involves a world of spread plates and colony counting. I was wondering if anyone has experience of using one of those colony counting pens…
-Would you recommend it? (or is it a waste of money?)
-If you do recommend it what brand is best? (or is there little difference?)
-Is there such a pen which can record the count information from multiple plates? (or does it simply add up the total counts?)
Any information would be greatly appreciated.
