AP Series – Advanced Performance UniBloc Balance / Semi – Micro Analytical Balance

Your Location: Main > Equipment > Balance

Highly-sophisticated simulation technology produced advanced UniBloc AP ™
Increased weighing capacity from 135mg to 220g (0.01mg model)

Micro amount weighing over 135mg (read 0.01mg step) is possible.

Faster Response and Higher Stability

High Speed – Fast weighing response
The response time for trace measurements (from 1 mg) is reduced to about 2 seconds. This significantly improves weighing efficiency.

Stress Free – A variety of accessories and options suitable for semi-micro measurements
The STABLO-AP ionizer can be mounted.
This eliminates the influence of static electricity, achieving reliable measurements in a simpler procedure.

For Regulation-for the Pharmaceutical Industry
Interlocking with LabSolutions Balance enables compliance with a variety of regulations for measurement data integrity, including ISO 17025 for testing laboratories, ISO 9001 and ISO 14001 for the manufacturing industry, and GLP/GMP and the United States Pharmacopeia (USP) for the pharmaceutical industry.

Functions are included for the preparation of buffer solutions used in HPLC.
As a result, the operation can be performed accurately and easily, even by non-specialists.

Save Your Operation
Equipped with USB as standard. Includes many diverse functions to support users.

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 efciency of measuring operations.

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)
