In case you’ve missed our recent activity, here is a summary of the new products we made available this year. Look for more exciting product testing solutions and post-column applications in the New Year!
1700-0165 Sodium AA Standard with Norleucine
Expanded amino acids standard for hydrolysate samples.
1700-0542 Sweat DIN EN – IEC 60068-2-70. Not Stabilized
1700-0543 Sweat DIN EN – IEC 60068-2-70. Stabilized
Abrasion of markings and letterings caused by rubbing of fingers and hands. This formulation is intended to provide a standard method to determine the resistance of markings and letterings on flat or curved surfaces against abrasion as it may occur by manually operating actuators and keyboards. The method is also suitable to test the resistance against fluid contamination as it may occur under normal use.
1700-0556 Artificial Apocrine Sweat non-stabilized 250mL.
Apocrine sweat is secreted by apocrine glands located in the areas of the body with an abundance of hair follicles such as the scalp, armpits and groins. Apocrine sweat is initially sterile and odorless but when acted upon by bacteria it forms odorous compounds. Artificial Apocrine Perspiration was developed to mimic the composition of human apocrine sweat and contains several volatile fatty acids that are responsible for the unpleasant odor associated with it. The ready-to-use solution is stored frozen and could be used for testing that requires the presence of malodor. It also could be used to culture bacteria that are commonly present on human skin.
1700-0557 ISO 3160, 19.8L, Stabilized
This formulation is used to determine corrosion (tarnishing, oxidation and surface penetration) resistance for gold alloy coverings on watch cases and accessories, including bracelets when they are permanently attached to the case. The solution is at pH 4.7 per ISO 3160 specifications.
1700-0558 Artificial Urine DIN EN 1616, Stabilized, 200mL
1700-0603 Artificial Urine DIN EN 1616-1999, 19.8L
Artificial Urine is prepared according to DIN EN 1616:1999 standard procedure. DIN EN 1616 specifies the method to test sterile urethral catheters. This ready-to-use solution should be stored frozen to avoid bacteria growth. The pH of the solution is 6.6.
1700-0800 Simulated Lung Fluid, Gamble’s, Not Stabilized, 200mL.
Gamble’s solution represents the interstitial fluid deep within the lung and is used to simulate different lung conditions. It is used in pulmonary drug delivery studies as well as in studies of particles inhalation effects. Citrate is used in Gamble’s solution instead of proteins to avoid foaming and acetate instead of organic acids. Gamble’s solution has a pH of 7.4.

1700-0801 Substitute Ocean Water, ASTM D1141-98
Substitute ocean water is prepared according to official ASTM method D1141-98. This product could be successfully used in a wide variety of tests where solution simulating sea water is required, such as oil contamination testing, detergent evaluation and corrosion testing. The pH of the solution is 8.2.
