AP Series

The diverse functions

High Speed -Fast measurement significantly improves operational efficiency.

Fast Response with UniBloc AP Technology

Shimadzu analytical balances boast a one-piece UniBloc weighing sensor, which is now even more advanced.
The response time is reduced to about 1/5 the time of previous models.
The improved UniBloc sensor offers a response time of just 2 seconds, an improvement from 10 seconds with the previous model.

Response During Trace Measurements with the 0.01 mg Model
(Equivalent to 1 mg / With Conditions Set by Shimadzu


Advanced Digital Control for Fast, Reliable Weighing

The improved measuring feel provides more comfortable use.

Measuring feel has been significantly improved by using the advanced digital control technology and smoothing technology.
AP-i system provides reliable weighing even in an environment with significant external disturbances. This promises to increase the efficiency of your measurement operations.

Stress Free

The multi stand can be used freely and easily. (0.01 mg model only, equipped as standard) 

With weighing paper, for example, if the tare is larger than the pan diameter, measurements can be simplified by attaching the special multi stand.

Measuring weights with a pipette can be simplified by placing a micro tube upright in the sample holder in the special multi stand.

Long rod-shaped samples can be measured in a stable state by placing them in the slot in the special multi stand.

The internal windbreak plate suppresses the influence of convection and airflow within the weighing chamber, improving the stability and response of measurement values.

Built-in High-Performance Ionizer (Optional)

The ionizer eliminates influence of static electricity in 1/10 the time of previous models.
Note: Example of typical static electricity removal time (±1000 V → ±100 V) 1 sec. for STABLO-AP and 10 sec. for STABLO-EX

AC Method with Excellent Ion Polarity Balance
Mount the STABLO-AP in the balance and use it as a built-in model

High-Security User Management

Operations can be kept secure with user ID and password protection. Access rights can be specified separately for each user to prohibit unauthorized actions such as performing calibration or changing the settings. User IDs can also be used for barcode management.

Printing Data in Accordance with Various Regulations

Printing can be customized to indicate when the measurements were taken and by whom. Users are free to set which items are to output, and in what order. The date, time, calibration log, and other information can be printed depending on the purpose of printing, which supports compliance with ISO, GLP, and GMP.

Minimum Measurement Value (Warning Function)

Reproducibility can be confirmed by repeatedly measuring weights as instructed by AP series. The minimum sample quantity is automatically determined from the standard deviation and recorded in AP series. If the minimum sample quantity requirement is not satisfied during measurement, an indicator flashes to warn the user.


Recipe Function (Achieve Your Preferred Compounding Process)(AP-W Series only)

Sample recipes can be registered, allowing users to simply follow displayed instructions. This is convenient when compounding medicines.

Solutions to Improve Operational Efficiency and Ensure Data Reliability LabSolutions Balance Analytical Network Data System Compliant with ER/ES Regulations

  • Eliminate manual entry, and all the weighing data are saved automatically in a safe database without transcription mistakes.
  • Reports appropriate for weighing methods, such as the mass variation test, drying weight loss test and particle size test, can be created automatically after the measurement. In addition, customized reports featuring such information as system conformance, content uniformity and elution tests together with the analysis results obtained by HPLC, etc. can be created.

Integrated Management of Analytical Data on Network System Using LabSolutions

Compliant with the Latest Data Integrity Guidance (U.S. FDA 21 CFR Part 11)

  • Weighing results can be automatically saved in the database together with other information, including sample ID, operator name, operation date and series number of instrument used.
    This enables quick data searching based on sample information.
  • It allows setting up user authority to ensure only the authorized user can create a template for weighing.
  • It prevents improper manipulation, unintended overwriting and deletion of data. In addition, measurement results, all the operation histories and reasons will be saved in the database as log files.

Integrated Report Creation Function Combines Analysis Results from HPLC and Weighing Results from Balance

Save Your Operation    (USB host: AP-W Series only)

USB Offers Greater Expandability

Equipped with an RS-232C connector, a USB device and a USB host as standard. You can now simultaneously send output to both a computer and printer or connect a USB flash drive, a barcode reader, or an external numeric keypad.
Transcription errors can be avoided and data can be recorded without a computer.


USB flash drive

Connecting a USB memory device allows you to record large amounts of weighing data in CSV format. Used in combination with the interval output function, it also enables recording of long-term changes over time.


Example of a record:
File name
Date and time
Weighing value


*The information saved will differ depending on the function used.



Display capture function

Weighing display can be recorded into USB memory in BMP format. User name,
date/time, and setting can be shown with display information.
The user name, time, measurement conditions, pass/fail judgments, and other information displayed on screen can be saved as is, enabling the recording of measurements, and checks after measurements.


Numeric keypad

Connecting a common external numeric keypad makes it easier to enter numeric values. This is especially useful for entering the mass value of weights, setting upper/lower limit values for the comparator function, or entering the sample count during piece counting mode.


Barcode reader

A barcode reader can be connected. Simply reading a barcode makes it possible to input user ID/Password. It is possible to manage sample IDs using barcodes.

An ID and password are needed to log in to the AP series if protected access is activated. With the barcode, an operator can log in by scanning the barcode instead of inputting an ID and password. * The latest information can be seen from the Shimadzu website (https://www.shimadzu.com/an/balance/)


Easy-to-Read Organic EL Display (All models)

Because the pixel elements in the organic electroluminescence display emit light, the screen can be seen clearly even in dark locations.
Multi-language display capability*2 provides a more intuitive operating interface. A wider viewing angle has also improved the visibility of measurement values, which helps increase the efficiency of measuring operations.
*2 Japanese, English and Chinese

Exceptional Visibility
The visibility remains the same even when viewed from different angles. The viewing angle is a wide expanse of ±85 degrees, both vertically and horizontally. That means the display is clearly visible even when working beside the balance. A high-resolution dot-matrix display makes it easy to read detailed text.


Periodic Inspection Support Function (AP-W/AP-X Series only)

AP series supports periodic inspections. The function allows inspection of repeatability, corner load error, and linearity by simply following instructions displayed on the screen.
