Index instruments gpr 12-70

The GPR 12-70 is normally supplied with a standard hinged sample cover (type FC1) illustrated below. This very popular cover gives close temperature control when connected in series with the thermostatting fluid flow to the prism jacket. The GPR 12-70E is a general purpose model, specially designed to measure the Refractive Index (RI) or Brix of samples of a wide range of temperatures from about 20°C upwards and is especially suited to high temperature measurements up to 100°C. GPR 12-70 wide range - RI 1.32 to 1.68 - Brix 0 to 100% reading to 4th decimal place of RI (or 1st decimal place of Brix) GPR 12-70X enhanced accuracy model, same wide range as GPR 12-70, reading to 5th decimal place of RI and 2nd decimal place of Brix. The GPR 12-70 has a built-in temperature corrected refractive index measurement scale which can be used if a thermocirculator or other constant temperature control device is not available. The instrument must be programmed to take account of the sample temperature coefficient. See instruction manual for details. HEALTH AND SAFETY Specifications.

The refractive indices of the sodium naphthenate–water mixtures were measured using an automatic refractometer (Model GPR 12-70, Index Instruments, US, Inc.). All refractive index measurements were performed at a wavelength of 589 nm and a constant temperature of 23.0 ± 0.1 ° C. The refractive index values are shown in Table 1. The GPR offers a wide range of used geophysical instruments and accessories for sale and rentals, as well as the sales of new equipment from Bartec Syscom, ABEM and Nomis Seismographs. We also offer maintenance and calibration services for Bartec Syscom and NOMIS's equipment.

With almost 40 years of scientific instrument manufacturing experience, Index Instruments has built an unparalleled reputation for reliability and quality in the specialized field of This model is perfect for all samples that easily pass through a 5.5mm bore tube. Its hinged locking mechanism for easy cleaning is another advantage. Just right for volatile samples or samples that are undesirable to handle. Can be filled using a small volume syringe or use the GPR 12-70 with an AutoSampler and Index Pump 300 peristaltic pump. Solutions of bitumen and solvent were mixed on a bench top shaker for a minimum of 2 h. The RI of the solutions were then measured using an automatic refractometer (Model GPR 12–70, Index Instruments U.S., Inc.). All measurements were performed at a wavelength of 589 nm and a constant temperature of 23.0±0.1°C. refractometer of the firm Index Instruments UK, type GPR 12-70, was used to determine the Soluble Solids of the fruit samples. Results were expressed as Brix at 20oC. Glucose, fructose and saccharose were determined with an HP 1100 Series High Performance Liquid Chromatograph (refractive index detector (RID) using a reverse phase column

Working with a leading manufacturer of contact lenses, Index Instruments have developed the CLR 12-70 fully automatic refractometer. This instrument will allow you to measure refractive index, water, or solids content of gas permeable and soft contact lenses. The CLR 12-70 measures clear or colored iris lenses with equal ease and accuracy.

PC Software is available from Index Instruments Ltd. to connect your TCR to or the GPR 12-70 or GPR 12-70X which use flowing fluid to control both prism and
