Now, more and more users will require that the tip is free of RNase, DNase, DNA, pyrogen and ATP contamination. This is a good phenomenon, but two points have to be reminded: [ 1000 Pipette Tips,20ul Tips Pipette,Pipette Tips 1000,Active Filter Tips,100ul Pipette Tips ]First, high-temperature sterilized tips cannot completely guarantee the absence of biological contamination. To ensure that there is no biological contamination, steps such as gamma ray treatment are required. Therefore, it is almost impossible for users to dispose of ordinary tips into non-biologically contaminated tips, and the purchased non-biologically contaminated boxed tips must provide corresponding certificates to indicate the test data of the corresponding items. A tip without data or even a certificate cannot be proved to be completely pollution-free; [ 1000 Pipette Tips,20ul Tips Pipette,Pipette Tips 1000,Active Filter Tips,100ul Pipette Tips ]second, bagged tips cannot be guaranteed to be free of biological contamination. As long as the tip is in contact with air, it may be contaminated by organisms, and ordinary ziplock bags cannot guarantee that the tip will not contact air at all during storage and transportation; in addition, the ziplock bag may sometimes be punctured by the tip happen. Therefore, if you have relatively high requirements for the suction head, you must check with the supplier before purchasing whether the suction head has a certificate indicating the corresponding item test data.
