Capp Paperbox FAQ

Q1: Are the PaperBox Tips sterile and PCR clean (DNAse / RNAse, human DNA, Reverse-Transcriptase- and PCR inhibitor free)?

Capp PaperBox carton racks for Filter Tips are pre-sterile and PCR clean. Each PaperBox is packed in a single foil to ensure sterility is maintained.

Q2: How long will the PaperBox remain sterile?

Similarly to the polypropylene racks, it is important to always use a newly opened box to ensure there is no contamination. Therefore, older opened racks from the fume hood could be best used up for applications where sterility is not needed.

CAPP Filter Tips

Q3: Can the PaperBox racks be used as reloads only or could they also be reused?

Capp PaperBox carton racks for Filter Tips are a great eco-friendly alternative to standard racked tips. Moreover, after using up the filter tips supplied from the PaperBox, the carton racks can be reused for a few more cycles as an alternative to the conventional PP racks, along with the non-filtered tips from our reload systems when sterility is not necessary.

Q4: Are the PaperBox racks autoclavable?

Since cellulose absorbs water, the Capp PaperBox is not steam autoclavable. But if you want to ensure the sterility of your half-used PaperBox, you can use the PaperBox insert plate as a reload for the autoclavable polypropylene racks. The autoclavable PP racks are also packed in user-friendly and space-saving dispenser boxes.

Q5: Can one mount the tips on a multichannel pipette from a Paperbox?

Paperbox works best in combination with single channel pipettes. For multichannel pipettes the best option is to use the Filter Tips delivered in the PaperBox as a reload for the PP box or to switch to reload-system for non filtered tips.
