1. INTRODUCTION

The PT series Pipette Accuracy Tester performs an accuracy test of the volume of a pipette in

accordance with ISO 8655.

This manual describes how the PT series Pipette Accuracy Tester works and how to get the most out

of it in terms of performance. It includes how to assemble the tester, how to measure and how to use

the software, WinCT-Pipette, for pipette accuracy testing.

Read this manual thoroughly before using the tester and keep it at hand for future reference.

For detailed information on handling the balance, refer to the instruction manual for the balance used.

NOTE ISO 8655 is the international standard that includes pipette calibration and specifies a test

method for accuracy of the pipette volume. For detailed information, visit our web site.

1-1 Unpacking the Tester

NOTE The pipette accuracy tester is contained in a carrying case. The case is only for

carrying the tester and is not solid enough to endure transportation. So, do not

transport the tester using the carrying case. When transporting the tester, be sure to

use the original packing material.

When handling the tester, be careful not to drop it, even if it is placed in the carrying case.

The illustrations on the next page show what the PT series consists of.

Note that the USB converter is shipped in a separate package, but it can be placed in the carrying

case as shown below.

A shoulder belt and a key are provided with the carrying case. Use the shoulder belt to carry the

case.

NOTE Please confirm that the AC adapter type is correct for your local voltage and power

receptacle type.

AD-4212B-PT / AD-4212A-PT

The connection cable provided as an accessory is one meter long.

1-2 Description of Each Component

zEvaporation trap

A chamber to prevent the evaporation of the dispensed test liquid.

(Refer to “1-4 Function of the Evaporation Trap”.)

zSample cup (Two types: 5 mL and 30 mL)

A cup to contain the test liquid dispensed from a pipette.

zTest liquid cup

A container to keep a test liquid such as distilled water.

zThermometer (with a clamp)

Measures the temperature of the test liquid.

zRS-232C cable and USB converter

Connects to a PC (personal computer) to transmit the test values to the PC.

zWinCT-Pipette

Software for pipette accuracy testing to convert the test liquid mass

into a volumetric value.

zCalibration weight (with a pair of tweezers to handle the weight)

A weight to calibrate the balance.

1-3 WinCT-Pipette, Software for Pipette Accuracy Testing

Features

The mass value of the distilled water dispensed from a pipette is transmitted from the balance to a

PC. Using the temperature of the test liquid and the barometric pressure that are previously entered,

the PC calculates the conversion factor (Z factor) from a mass value to a volumetric value and

converts the mass value into a volumetric value automatically, using the Z factor.

The measurement results are compared with the specifications previously entered, to perform

judgment whether the pipette will pass or fail.

Besides the pipette volume, test numbers, test dates and pipette information (manufacturer, model,

serial number) can be recorded as test data. The test data, output to a printer or stored in the PC,

allows easy management of pipette accuracy and reduces errors due to data mismanagement.

The specifications of accuracy and repeatability can be entered either as an absolute value (μL)

or as a relative value (percentage to the pipette volume).

The mass value data from the balance can be transmitted to the PC either using a COM port or

using a USB connection. (For a USB connection, use the accessory USB converter.)

For testing various pipettes easily, multiple test conditions (pipette volume, number of

measurements and specifications) can be set previously. When multiple operators are set

previously, an operator can be selected easily as necessary.

NOTE For detailed information on WinCT-Pipette, refer to “How to use WinCT-Pipette.pdf” in the

WinCT-Pipette CD-ROM.

1-4 Function of the Evaporation Trap

In the pipette accuracy test using the gravimetric method, to obtain the mass of the test liquid, distilled

water is dispensed from the pipette into the sample cup installed on the balance. The obtained value,

however, is generally smaller due to evaporation loss of the test liquid. To prevent evaporation of the test

liquid, the evaporation trap is used. The ISO 8655 standard recommends that the humidity of the

measurement environment be greater than 50% RH.

Water is poured into the groove of the evaporation trap. This helps to maintain the humidity inside

the evaporation trap high and reduces evaporation. Using the evaporation trap reduces the

evaporation of the test liquid to about 25% or 0.05 mg per minute, compared with the value when the

evaporation trap is not used. This yields a measurement environment where there is no need to

consider measurement errors due to evaporation loss of the test liquid.

Another function of the evaporation trap is one as a breeze break, to prevent drafts in the

measurement environment from influencing the weighing operation and enable a stable weighing.

The evaporation trap is designed for an easy dispensing of the test liquid. The upper part has a

sloped surface so that the pipette can be inserted from obliquely above.

The Z factor is automatically calculated using the values o

the distilled water temperature and the barometric pressure.

Measurement environment

Enter the ambient relative humidity,

the distilled water temperature and
