We are using the Leica Microdissection system which drops cut out cells into lids of 0.5 ml PCR tubes, that are secured in a special metal holder. Now that our batch of Eppendorf tubes have run out we wanted to re-order them but turns out they have been discontinued. The new Eppendorf 0.5 ml PCR tubes (Cat nr. 0030124537) have a bigger lid that doesn't fit in the holder. Does anyone who uses this sytem has an alternative?
