Precision Under Extreme Conditions

Hamilton (Switzerland) SaltLine syringes stand out because of their exceptional resistance. Conceived for use in connection with the tried and tested Hamilton Microlab 600 Diluter/Dispenser, they allow precise dosing even under extreme environmental conditions. Thus, they meet the toughest day-to-day requirements of challenging industries such as the mining and chemical industries.

Aggressive media or saturated salt solutions, as they are used in the mining and chemical industries, make very high demands on the performance of analytical syringes. Hamilton SaltLine syringes were specifically designed for resisting the toughest working conditions. Even in the most difficult applications, they guarantee the precise dosing of highly concentrated buffer solutions for long periods.

The plunger sealings of SaltLine syringes are made from chemically inert and mechanically resistant ultra-high molecular weight polyethylene (UHMWPE). When handling 5% sodium chloride solutions, they last twice as long as conventional PTFE sealings. Not only is their sealing force constantly high, but they also resist numerous aggressive media and organic solvents as well as the abrasion caused by deposited salt crystals or other particles.

The plunger rods of the SaltLine syringes are made of fibre-reinforced, high-performance polyamide. Since no metal is present, they resist corrosion and also eliminate the distortion of measuring results caused by migration of metal ions.

The wetted syringe surface is neutral. All fluid paths are fully inert and made of glass, UHMWPE, or fluorinated polymers. SaltLine syringes are ultra-precise; with a syringe partial volume of one percent, accuracy and precision lie between one and three percent at most (depending on the total volume used by the syringe). With an ejection of 100 percent, the syringes operate accurately down to 0.2 percent.

SaltLine syringes were conceived to be used exclusively with the Microlab 600 Diluter/Dispenser, the tried and tested fluid control device also from Hamilton. Thanks to the advanced dispensing technology based on the displacement principle, the Microlab 600 guarantees 99 percent accuracy—regardless of viscosity, temperature, and steam pressure. The high-resolution syringe pump even allows the programming of small sample volumes. More advantages of the device are higher precision and throughput plus lower buffer consumption compared to manual solutions. Since the Microlab 600 has a universal valve, users can also switch very quickly from one application to another.
