Manufacturer: Biochemazone
Available Pack Sizes: 100 mL, 200 mL, 500 mL, 1 L
Custom Bulk Quantities Available
Product Overview
Biochemazone Simulated Lacrimal Fluid BZ370, also called artificial lacrimal fluid or synthetic lacrimal fluid, is a sterile, ready-to-use solution that simulates the composition and pH of lacrimal fluid. It is sterilized by 0.2 µm filtration and supplied at pH 7.4; the pH can be customized on request.
Lacrimal fluid is the fluid secreted by the lacrimal glands to lubricate the eye and fight bacteria. The natural fluid consists of water, mucin, lipids, lysozyme, lactoferrin, lipocalin, lacritin, immunoglobulins, glucose, urea, sodium, potassium and other components. BZ370 is used to study the in vitro release of medications and drugs given by the ophthalmic route, for in vitro studies of topical therapeutics applied to the eye – eye drops and topical ointment formulations – and for in vitro sustained drug release studies.
It is supplied stabilized and has a 1-year shelf life unopened; a preservative-free version (6-month shelf life) and a dried Powder Version Kit are available on request. Because it contains protein and mucin, keep it at 2–8 °C if it is to be stored for a long time. The pH and the contents can be customized to the project. This simulated fluid is for scientific research and in vitro use only; it is not for clinical diagnosis or treatment. For simulated tears see Simulated Tears (BZ182); for the lacrimal sac see Simulated Lacrimal Sac Fluid (BZ425); for tears with proteins and lipids see Artificial Tear Solution with Proteins and Lipids BZ612.

Frequently Asked Questions
What is lacrimal fluid?
The fluid secreted by the lacrimal glands to lubricate the eye and fight bacteria. BZ370 simulates its components and pH for in vitro release studies of ophthalmic medicines.
How should it be stored?
Store it at 2–30 °C; because it contains protein and mucin, 2–8 °C is best for prolonged storage. It is shipped at room temperature. Unopened, the stabilized solution has a 1-year shelf life; a preservative-free version with a 6-month shelf life and a dried Powder Version Kit with a 2-year shelf life are available on request.
