Abbemat Performance and Performance Plus Line

Abbemat digital refractometers allow fast and non-destructive refractive index measurements. They are factory calibrated with official standards from the Physikalisch-Technische Bundesanstalt (PTB, National Metrology Institute of Germany). Refractive index results from Abbemat 300/350 are accurate to ±0.0001 nD; Abbemat 500/550 provides an accuracy of ±0.00002 nD.
All Abbemat 300/500 refractometers provide full compliance with 21 CFR Part 11, with user levels, audit trail, and forgery-proof data export. Anton Paar also provides a qualification documentation package (IQ/OQ/PQ). The Abbemat T-Check feature precisely calibrates and adjusts the surface temperature of the measuring prism of all Anton Paar refractometers.

Key Features

Easy operation

Abbemat 350/550 refractometers are set up conveniently using intuitive touchscreen navigation
Abbemat 300/500 have a color LCD screen and membrane keys which are resistant to spillage and dirt and can be operated even when wearing gloves
A reminder for test measurements or adjustments can be set at user-defined intervals
Automatic warning if the sample volume is not large enough for a valid measurement
No sample preparation, readings within seconds
A quick wipe cleans the prism after each measurement

Compliance and traceability

Full compliance with 21 CFR Part 11
Compliant with international standards such as ASTM, ICUMSA, OIML, AOAC, DIN/ISO, FDA, ISI, JIS and pharmacopoeias
History and current status of results via the result memory
Adjustment and check history, check intervals and validity checks for each measurement

For all samples

Independent of sample properties you can measure:
- all samples from liquids to pastes, polymers to solids
- turbid, colored or opaque samples
- liquids containing air bubbles or solid particles
No influence from humidity, temperature or vibrations
A wide range of scales are stored in the Abbemat for converting refractive index into concentrations, etc.
