DS7800 Density meters for fully automatic sample supply Set 4
Fully automatic execution of the entire measuring process. Working environments involving a high sample throughput require flexible, powerful and robust solutions for a fully automatic execution of the entire process from the sample supply to the cleaning and drying. Our AS80 and AS90 autosamplers meet these high requirements. Together with the peristaltic pump DS7070, they allow for an unsupervised measurement of up to 89 samples. Suitable for low-viscous to slightly viscous and aggressive samples.
Set 4 consists of: density meter with glass U-tube oscillator; drying unit with 3/2-way valve; peristaltic pump; autosampler for 18 or 36 samples including sample plate 18x 50 ml (42 mm x 43 mm) or 36x 35 ml (28 mm x 65 mm), set polypropylene vials (50 ml) or glass vials (35 ml), PTFE connecting tube; or autosampler for 53 or 89 samples including sample plate 53x 16 ml (22 mm x 55 mm) or 89x 6 ml (16 mm x 55 mm), set polypropylene vials (16 or 6 ml), PTFE connecting tube; Tygon tube set for use with drying unit DS7060 (suction tube 320 mm, drain tube 320 mm, air tube 320 mm, waste tube 320 mm, tube connection Luer 3 pieces); tube set for peristaltic pump DS7070 (TPE pump tube 105 mm 5 pieces, PTFE tube connection olive 2 pieces); adaptor olive/UNFa for connecting the Tygon tubes to the drying unit DS7060; adaptor UNFi/Luer for the sample supply with autosampler AS80 or AS90 via Luer nozzle; Luer nozzle 2 pieces; Luer syringe 2 ml (10 pieces); Luer syringe 10 ml (10 pieces); PE waste container with lid (600 ml).

A comprehensive quality assurance covering the entire production process is a must in any industrial sector. Density measurements are frequently used for this purpose, especially in the pharmaceutical, chemical, petrochemical as well as the food and beverage industry. They allow the manufacturer to analyse raw materials, semi-finished and finished products as well as the manufacturing steps in terms of a number of factors.
Density can be used to identify substances, to determine their quality or purity and to measure their concentration in binary or quasi-binary mixtures. Substance conversions and reaction dynamics can also be inferred from it. In combination with other methods such as refractometry that measures the refractive index of substances, the density measurement allows you to make precise statements about the quality of each step of the production process.
Density meters based on the oscillating U-tube method are characterized by high ease of use and are therefore used in particular for continuous density measurement and for rapid routine measurements with larger numbers of samples in laboratories.
