Production facilities throughout the World rely on refractometers and polarimeters for quantity and quality control. No matter what the make or type of instrument, results are only as good as the calibration regime behind the measurement. GLP dictates that instruments should be kept in good working…

The Abbe 5 is an affordable refractometer ideally suited for use where a wide refractive index measurement range is required such as in small contract laboratories or applications where sample throughput is relatively low. The instrument is also ideal for practical demonstrations and experiments in…
