Simulated Lung Fluid

Respiratory tract fluid is a complex, still not well-characterized mixture containing salts, locally secreted proteins, lipids, surfactants and other compounds. Respiratory fluid is also not homogeneous and has unique regional characteristics. The simplest simulated lung fluid, called Gamble’s solution, is a physiological salt solution that has been used to study drug dissolution as well as the solubility and bioavailability of toxic compounds found in inhaled particles.

Simulated Lung Fluid 

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.

Artificial Cerumen

Cerumen, also known as ear wax, is a waxy substance secreted by ceruminous and sebaceous glands in the ear canal. It protects and lubricates the ear canal and assists in cleaning by trapping dirt and dead skin cells. Pickering Laboratories’ artificial cerumen product is similar in properties to the secretion itself and doesn’t contain keratin or other proteins.

Artificial Cerumen 

Pickering Laboratories offers artificial ear wax that can be used for testing of hearing aids, ear buds and other electronic devices mean to be used in the ears. It contains lanolin, long chain fatty acids and
paraffin oil.

Artificial Sebum

Sebum is an oily secretion produced by sebaceous glands, which spreads over the hair and skin for waterproofing purposes. Pickering Laboratories, Inc. manufactures an artificial sebum formulation according to ASTM designation D4265-14 or D4265-98. It is readyto-use and provides the reliability, reproducibility and convenience needed for testing. This formulation can be used according to AATCC Standard Test Method 130-2010 for evaluating the efficacy of home laundry products and conditions to remove stains from fabric.

 

Simulated Waters

To address environmental product testing applications, Pickering Laboratories now offers Hard Water Substitute, manufactured according to ASTM E1945-02. The solution contains precise amounts of Calcium and Magnesium ions and comes in three levels of hardness. The ASTM method addresses the testing of pesticides dispersibility, but the hard water substitute could be used to test cleaning agents as well as lathering and other processes affected by water hardness. We also offer Substitute Ocean Water, prepared according to ASTM D1141-98 official method, and Simulated Sea Water for permeation testing according to Test Operations Procedure 08-2-501A.

Substitute Ocean Water ASTM
D1141-98 (2003)

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.

The solution is ready to use and is stored at room
temperature. Inquire about different sizes.
