Abbemat 450
• The robust design allows precise refractive index (+/-0.0001 nD) and concentration measurement in harsh environments
• Waterproof measuring unit (IP68) to withstand high amounts of spilled liquids
• For routine quality control under conditions where others fail

Abbemat 650
• Highly precise refractive index (+/-0.00002 nD) and concentration measurement in harsh environments
• Waterproof measuring unit (IP68) to withstand high amounts of spilled liquids
• The ideal tool for demanding quality control and R&D applications

The refractometers of the Heavy Duty line are designed for measuring the refractive index under harsh environments and in special applications. To withstand rough conditions they have a hermetically sealed aluminum casing.
The Abbemat 450/650 refractometers are extremely robust and waterproof (IP68). To measure samples containing solid particles or air bubbles you can position the Heavy Duty Abbemat on its side to prevent that sedimentation and disturbances affect the results. A separate control unit allows for convenient operation from a remote position.

Unique performance – reliable results within seconds
Highest analytical performance and stability guarantees accuracy into the 5th digit.
• Widest temperature control range in its class with 4 °C to 125 °C
• Stable temperature within a few moments
• Modularity with other Anton Paar instruments, e.g. density meter and viscometer

Measures when others fail
The Abbemat Heavy Duty Line withstands the roughest operating conditions.
• Measurement unit in a water-proof anodized aluminum housing (IP68)
• Remote operation, e.g. under fume hood by separated measurement and control unit
• Stainless steel or Hastelloy B3 sample well to withstand the most aggressive chemicals

Ideal solution for quality control and concentration measurement
The Abbemat Heavy Duty line consists of your high-end instruments for concentration measurement of your binary solution. Anton Paar offers the easiest quality control possible. Over 200 available methods from acids to Zeiss guarantee access to the concentration of common substances.
• Refractive index
• Pharma (methods acc. to Ph. EU / US / JP)
• Food (e.g. Brix, sucrose, glucose, iodine value)
• Beverage (e.g. Brix, invert sugar, sucrose, Zeiss)
• Chemicals (e.g. sodium hydroxide, sulfuric acid)

Integrity by design
The Abbemat line is the gold standard for refractometers regarding data integrity and compliance in regulated environments.
The software fully supports the requirements of the pharmaceutical industry, including GMP, 21 CFR Part 11, GAMP 5, USP, and international pharmacopeia (e.g. Ph. Eur., JP). User management, audit trail, check and adjustment history, and electronic signature are just a few examples of the powerful pharma-compliant configuration possibilities of the Abbemat line. To minimize the time it takes to integrate your new Abbemat into your workflow, Anton Paar offers a Pharma Qualification Package.
Additionally, Anton Paar provides attractive data management solutions for the Abbemat Heavy Duty line to guarantee highest data integrity.
