IKA PETTE fix 50 µl single-channel pipette, fixed volume, autoclavable, 0020011223

The precision benchmark for 50 µl: IKA PETTE fix

The IKA PETTE fix 50 µl (MPN 0020011223) sets a new benchmark for mechanical air-cushion pipettes in everyday laboratory work. The 50-microlitre volume is one of the most commonly used dispensing volumes in chemistry, biology and medical diagnostics – whether for dilution series, preparing buffer solutions or adding reagents in standard assays. The IKA PETTE fix was developed specifically for these high-frequency applications. It combines absolute repeatability with ergonomics that actively counteract signs of fatigue. As a fixed-volume model, it eliminates the risk of setting errors and guarantees that every pipetting operation delivers exactly the defined volume – an indispensable advantage for standard operating procedures (SOPs).

Ergonomics reimagined: the interchangeable handle system

Arguably the most striking feature of the IKA PETTE series is its adaptability. A ‘one-size-fits-all’ approach rarely works for hand tools, as every user has different anatomical characteristics. IKA therefore supplies each pipette with three interchangeable grip inserts. These grips differ in size and shape. They can be swapped without tools and allow the pipette to be individually tailored to the user’s hand size (small, medium, large).

• The advantage: the pipette sits comfortably and naturally in the hand. The centre of gravity is optimally balanced. Gripping the discharge button requires no repositioning of the hand or stretching of the thumb. This significantly reduces muscle strain and helps prevent the dreaded RSI syndrome (‘mouse arm’ or ‘pipetting arm’), even during long pipetting sessions.

High-tech materials for maximum service life

A pipette is a precision instrument that is subjected to heavy mechanical stress. To ensure long-term accuracy, IKA relies on DLC-coated components. DLC stands for ‘Diamond-Like Carbon’. Both the dispensing piston and the tip cone (tip seat) are finished with this extremely hard material. The advantages of this technology are immense:

1. Extreme hardness: The coating makes the moving parts resistant to abrasion. Even after tens of thousands of strokes, the system seals perfectly.
2. Low friction: DLC has excellent sliding properties. This means you need to exert significantly less force to press the plunger down. This is easier on your thumb.
3. Chemical resistance: The surface is inert and withstands aggressive vapours, acids or alkalis better than conventional stainless steel.

Uncompromising hygiene: Fully autoclavable

In sensitive fields such as molecular biology (PCR) or microbiology, sterility is paramount. Many pipettes have to be laboriously dismantled before they can be placed in the autoclave – often with the risk of small parts being lost or seals being damaged. The IKA PETTE fix 50 µl is fully autoclavable (at 121 °C for 20 minutes). You simply place the entire instrument in the steriliser. This saves valuable time and ensures maximum protection against contamination. In addition, the housing material is UV-resistant, which also allows for sterilisation under the UV lamp of a clean bench.

Easy maintenance and calibration

Should it nevertheless ever be necessary to service or clean the pipette (e.g. because liquid has been drawn into the shaft), the design is extremely user-friendly. The pipette can be dismantled in just a few simple steps. The piston and seal are easily accessible. Should an adjustment be necessary – for example, because you are pipetting liquids with a density that differs significantly from that of water (e.g. glycerine) – you can carry this out without tools. The calibration volume can be easily adjusted without having to send the device in for servicing.

Universal compatibility

The tip cone of the IKA PETTE fix 50 µl is designed to be compatible with pipette tips from almost all leading manufacturers. You are not forced to buy expensive proprietary tips, but can continue to use your existing standard tips (usually the yellow 200 µl tips). The cone is also shock-resistant, which minimises the need for costly repairs should it be accidentally dropped.

Design and readability

The award-winning design (German Design Award, iF Design Award) combines aesthetics with functionality. A large display shows the nominal volume “50 µl” clearly and distinctly. As this is a fixed-volume pipette, this display is static – which rules out any confusion in the hectic day-to-day of laboratory work. Every time you pick up the pipette, you can be sure: “That’s 50 µl, nothing else.”
