NEW AP W-AD ex Series / AP W ex Series
Accurate Weighing. Next-Level Innovation.
Comfort and Trust in Every Weigh.
01 Precision Weighing

Now with Significantly Enhanced Repeatability.
The minimum weighable quantity specified by the United States, European and Japanese pharmacopoeias has been improved from 20 mg in conventional models to 13 mg*, enabling analysis with smaller sample volumes.
*Compliant with the Japanese Pharmacopoeia, USP 41 and Ph.Eur.2.1.7.
Minimum weight value is met at the Shimadzu Corporation factory using weights equal to approximately 5 % of the weighing capacity.
This value is affected by the installation environment, so it is necessary to measure it in the actual environment of use.
02 Reliable Weighing
A AP Holder, ideal for accommodating various glass container sizes, is included as a standard accessory.
Effectively eliminates static from glassware and samples on the weighing pan when paired with the STABLO-AP ionizer.
03 Comfortable Operation
Carries forward the user-friendly features of earlier models.
Touchless sensor keys and a Smart Auto Door (featuring learning and manual trigger functions) reduce the physical burden of weighing tasks, providing a more comfortable weighing experience. Touchless operation also ensures highly reliable measurement.
Advanced Performance UniBloc Balances
Provides High-Speed Response and High Stability
The AP-AD series models not only offer excellent basic performance, such as fast weighing times of about two seconds and high measurement stability that minimizes errors, but also include new functionality that improves convenience, such as automatic doors and touchless sensors.
Automatic door functionality makes weighing operations even more convenient.
Features
-
The minimum weighing value is significantly improved, from 20 mg for the previous model to 13 mg for the new models. That means smaller sample quantities can be easily analyzed accurately. The minimum weighing value is affected by the installation environment, so it is necessary to measure it in the actual environment of use.
-
The W-AD series features automatic doors.
That means operators can continue working without setting down samples or spatulas, which can help shorten overall measurement times. -
The response time for trace measurements (from 1 mg) is reduced to about 2 seconds. This significantly improves weighing efficiency.
-
Equipped with USB as standard. Includes many diverse functions to support users.
