1.2.4 Biohit Optifit Tips and SafetySpace™ Filter Tips
It is recommended that Optifit Tips or SafetySpace Filter Tips are used with
Sartorius Biohit pipettes. This ensures the best possible compatibility and thus
best possible accuracy and precision, as the tip is designed for the pipette in
question.
Additional pipetting instructions to achieve good results are as follows
– The liquid and the pipette/tip combination should be approximately at the
same temperature
– Choose the right tip volume for your pipette: the colour of the tip tray
should match the colour coding on the pipette
– Use Optifit Tips in rack, refill or bulk packaging and choose the purity level
your application requires: DNase, RNase and endotoxin-free and/or pre-
sterilised
– In case you need to be aware of aerosol contamination, you may choose
between Safe-Cone Filters, which are attached to the tip cone and should
changed daily, or SafetySpace Filter Tips, which are discarded after each
pipetting
– Choose SafetySpace Filter Tips also when you want to avoid lost samples
due to the sample reaching the filter. The small extra space between the
sample and the filter ensures that neither foaming nor viscous liquids, nor
any sample when you are using reverse pipetting or repetitive/multiple
dispensing mode of the electronic pipette, will touch the filter.
– Pre-rinse the tip 3-5 times before pipetting (especially important in forward
pipetting mode)
– After dispensing wipe the tip against the receiving vessel wall to retain the
last droplet
– Change the tip after every pipetting
