Khan Associates is the authorized Rudolph Research distributor in Pakistan, supplying genuine Rudolph Research Analytical polarimeters, saccharimeters, refractometers and density meters to laboratories nationwide. Rudolph Research Analytical has manufactured precision analytical instruments in the USA for over 50 years from its facility in Hackettstown, New Jersey, with more than 8,000 instruments installed in over 80 countries and an enduring reputation for accuracy, reliability and long service life.
For Pakistan, Rudolph is the reference name in optical rotation and refractive index measurement, the exact analysis that sugar mills, pharmaceutical labs and beverage producers depend on. Khan Associates delivers, installs and supports the complete Rudolph range, backed by calibration standards and after-sales service from Lahore and Karachi.
Khan Associates holds authorized distribution rights for Rudolph Research Analytical in Pakistan. Every instrument we supply is a genuine Rudolph unit built in the USA, through the official channel, with manufacturer warranty and access to Rudolph’s calibration standards and support. Rudolph is A2LA accredited and holds ISO/IEC 17025 accreditation for polarimeter and refractometer calibration, and supports its instruments for the life of the product, many manufactured decades ago are still in service today.
Our Rudolph Research range covers precision optical rotation, refractive index and density measurement. All product lines below are available in Pakistan with installation, calibration standards and after-sales support.
The Autopol series of automatic polarimeters and saccharimeters measure optical rotation for pharmaceutical identity and purity testing, essential oils, and sugar analysis. For Pakistan’s sugar industry, Rudolph saccharimeters read directly in degrees Sugar (Z) according to ICUMSA methods, the standard for pol testing of raw and refined sugar.
The J Series automatic refractometers measure refractive index and BRIX for quality control in sugar, food, beverage and chemical laboratories. With electronic temperature control and long-term repeatability, they support routine QC where consistent, operator-independent results matter, including the J27 portable refractometer for field measurement.
The DDM series automatic density meters measure density and specific gravity with patented VideoView bubble detection, for pharmaceutical, chemical, petroleum and beverage applications. The DDM 29 portable density meter brings the same accuracy to field and production-floor measurement with electronic temperature control.
The AlcoTest-RI measures alcohol proof and obscuration for distilleries and beverage producers, while Rudolph’s Standards Laboratory supplies BRIX calibration fluids and quartz control plates made to NIST and ICUMSA specifications. Automated sample handling systems complete high-throughput laboratory workflows.
Sugar Mills: Saccharimeters for pol testing of raw and refined sugar by ICUMSA methods, plus refractometers for BRIX in juice, syrup and molasses through the crushing season.
Pharmaceutical Laboratories: Polarimeters for optical rotation identity and purity testing under pharmacopeial methods, and density meters for specific gravity determination in QC.
Food and Beverage Producers: Refractometers and density meters for BRIX, sugar content and concentration control in juices, soft drinks and processed foods.
Distilleries and Beverage Alcohol: AlcoTest-RI and density meters for alcohol proof and obscuration measurement, reducing time-consuming distillation steps.
Chemical and Petroleum Laboratories: Density, specific gravity and refractive index measurement for raw material and product QC.
Essential Oils and Cosmetics: Polarimeters and refractometers for optical rotation and refractive index verification of essential oils and fragrance ingredients.
Universities and Research Institutes: Precision optical and density instruments for analytical chemistry teaching and research.
Rudolph instruments are known for outlasting decades of service, with units from the 1980s and 1990s still running today. That longevity only pays off with correct calibration and genuine support: our team supplies the traceable standards, handles installation and calibration, and provides the local service that keeps a Rudolph polarimeter or density meter measuring accurately for its full working life.
