Yes. All P.I.P. pipettes are resistant to common laboratory chemicals. The metallic parts of P.I.P. pipettes are covered with a protective anodized layer, which ensures their chemical compatibility.

It is recommended to clean P.I.P. pipettes using common cleaning agents such as water with mild detergents, or 60-70% ethanol. For more details, refer to the operating manual.

 In major cases tips are the cause of bad results in terms of precision. A poor quality tip can result in imprecision Not necessarily.

Yes, P.I.P. pipettes are fully autoclavable (Except for the detachable push button). The recommended procedure is to autoclave them for 20 minutes in the temperature of 120°C. There is no need of disassembly or recalibration due to autoclaving. For full details about autoclaving, refer to the operating manual.

Always use standard tips. Push upward on the tip ejector to make sure it is positioned properly.
Tip cones may be damaged. In this case, send the pipette to P.I.P. Company for repair.

Reverse pipetting is recommended to reduce the error with viscous or foaming liquids or when dispensing very small sample volumes. The excess solution aspirated remains in the tip and is discarded.

When pipetting viscous liquids, use reverse pipetting technique. Positive displacement instruments can be a good choice, too.

Pole Ideal Pars Co, recommend annual service for P.I.P. pipettes. Note: Pipettes service should be done only by P.I.P. technicians.
For more information refer to the operating manual.

After contact with corrosive liquids, the pipette should be cleaned. Take care to avoid scratches. Also you can use filter tips. For more details about cleaning and maintenance, refer to the operating manual.

To decontaminate the pipette, only disassemble the tip ejector & shaft and use suitable decontamination technique. For more details, refer to the operating manual.

Yes. All materials used for P.I.P. pipettes are UV resistant.

They can be put down on the laboratory bench – but never with a full tip.

All P.I.P. pipettes are covered by a warranty for 1 year against defects in materials and workmanship. They are also supported for a period of 5-year after-sale services. These periods begin from the date of purchase.

The systematic error describes the deviation of the dispensed volume from the nominal volume of the device, and is determined by establishing the mean value of (usually) 10 measurements.
The random error describes the mean variation of the dispensed volumes from the mean value of the dispensed volumes, and is determined by calculating the repeat standard deviation of (usually) 10 measurements.

The measuring values of the analysis scales are multiplied by the correction factor Z. This takes into account the density of the water at the relevant temperature and the relevant air.
For more information, refer to the pipette Standard Operating Procedure.

This may be a temperature problem. Please ensure that the pipette, the water used for testing, the tips, etc. are all at the same temperature. It is recommended that the pipettes be placed in the weighing room at least 2 hours before the test is performed. While measuring, ensure that transfer of heat from your hands is kept to a minimum level.

Calibration is always performed using distilled or deionized water (See ISO 8655-6).

P.I.P. certificate is included in each pipette box. It indicates that the accuracy of each pipette has been individually checked.

This can vary depending on the frequency of use of the pipette, the number of users of the device, the aggressiveness of the liquids to be dispensed and etc. However, a calibration should be carried out at least once a year. (See ISO 8655-6)

Accredited laboratories authorized to issue calibration certificates are responsible for the implementation of calibration.

No. P.I.P. pipettes don’t need regular greasing.

When pipetting chloroform, we recommend reverse pipetting technique.

Due to the increased vapor pressure, we recommend that the tip is prewetted at least 3 times and that the reverse pipetting technique is used.
