Artificial Subdural Fluid – Synthetic Subdural Fluid for Neurological Research, pH 7.2 BZ449
Product Code: BZ449
Manufacturer: Biochemazone
Available Pack Sizes: 100 mL, 200 mL, 500 mL, 1 L
Custom Bulk Quantities Available
Product Overview
Biochemazone Artificial Subdural Fluid BZ449, also called simulated subdural fluid, is a ready-to-use synthetic solution designed to replicate the properties of natural subdural fluid, at pH 7.2. Subdural fluid is the fluid found in the subdural space. It contains water, electrolytes and proteins, which mimic the physical and chemical characteristics of the natural fluid. The pH of natural subdural fluid is about 7.0 to 7.4; the standard formulation is set at 7.2. Its viscosity and density are matched to the natural fluid, and it stays stable through the test.
It is used in research and development to study the behaviour of fluids in the subdural space and to develop new technologies and procedures related to neurology and brain health. It is also used to test and calibrate medical devices and technologies that interact with or analyse cerebrospinal fluid, such as diagnostic tools for neurological conditions, and in training, where it simulates real-life scenarios involving subdural fluid without the use of human samples.
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, keep it at 2–8 °C if it is to be stored for a long time. The formulation, minerals, organic content and pH can be customized. This simulated fluid is for scientific research and in vitro use only; it is not for clinical diagnosis or treatment. For the epidural space see Simulated Epidural Fluid (BZ441); for the cerebrospinal fluid see Artificial Cerebrospinal Solution (ACSF, Sterile) (BZ178).

Frequently Asked Questions
What does BZ449 contain?
Water, electrolytes and proteins, at pH 7.2, with a viscosity and density matched to natural subdural fluid.
How should it be stored?
Store it at 2–30 °C; because it contains protein, 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.
