1. Introduction

The Sartorius Picus®/Picus® NxT electronic pipette, of the Biohit

family

, brings

ergonomics into a completely new level with its exceptionally lightweight and

compact design, and its ease of operation. This pipette, operating with the air

displacement principle, has been designed by an experienced R&D team, in

co-operation with laboratory personnel and ergonomists, to create instruments

for safe and comfortable pipetting with versatile functionality.

The Picus®/Picus® NxT is available in single and multichannel models (8 and

12-channel). Tip attachment and ejection is made safe and comfortable with

the Optiload tip-loading feature together with the electronic tip ejection

function. To improve safety by reducing the risk of contamination, replaceable

Safe-Cone Filters can be used in all Picus®/Picus® NxT models greater than 10

µl.

The fully electronic operation, the unique DC-motor, electronic brake and

piston control system, guarantee excellent accuracy and precision. The light

and easy-to-use adjustment wheel, on top of the pipette, enables fast selection

of the desired volume.

Picus® NxT follows in the footsteps of the design-awarded Picus®, which won

the German Design Award Special Mention 2014, the reddot design award

2012 and the Fennia Price Honorary Mention 2012. These awards strongly

reflect the user-friendly and high-quality design of the pipette.

Congratulations on becoming a new Picus®/Picus® NxT owner!

1.1 Intended Use

The Picus®/Picus® NxT pipette is intended to be used in liquid handling

applications for dispensing liquids in the volume range of 0,2 µl to 10 ml. It is

recommended to use Optifit Tips or SafetySpace Filter Tips to ensure the best

compatibility and performance with Sartorius pipettes.

This liquid handling device is designed and manufactured to be used

as general purpose laboratory equipment. This manual contains useful

information e.g. for good pipetting practice.

1.2.4 Optifit Tips and SafetySpace Filter Tips

It is recommended that Sartorius Optifit Tips or SafetySpace Filter Tips are

used with Sartorius pipettes. This ensures the best possible compatibility and

thus best possible accuracy and precision, as these tips are 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 code on the pipette

– Use Optifit Tips in rack, refill or bulk packaging and choose the purity level

your application requires: free of DNase, RNase and endotoxin, and/or pre-

sterilized

– 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

be changed daily, or SafetySpace Filter Tips, which are discarded after each

pipetting

– Choose SafetySpace Filter Tips also when you want to avoid loss of sample

due to the sample reaching the filter. The extra space between the sample

and the filter ensures that any sample, neither foaming nor viscous

liquids, reach the filter when in the reverse pipetting or repetitive/multiple

dispensing mode of the electronic pipette

– Pre-rinse the tip 3-5 times before pipetting (especially important in forward

pipetting mode)

– After dispensing, wipe the tip against the receiving vessel’s wall to catch the

last droplet

– Change the tip after every pipetting
