Description
Stuart Transport Medium is an essential solution for laboratories focused on the transport and preservation of clinical specimens. This semisolid, chemically defined medium is specifically designed to maintain the viability of diverse microorganisms, including gonococci, streptococci, and enterobacteria. Ideal for throat, vaginal, and wound samples, this medium ensures accurate and reliable microbiological testing.
Key Ingredients: The formula includes:
- Sodium Glycerophosphate (10.0 gm/liter): Acts as a buffering agent.
- Cysteine Hydrochloride (0.5 gm/liter): Enhances anaerobic conditions.
- Sodium Thioglycolate (0.5 gm/liter): Prevents oxidative stress.
- Calcium Chloride (0.1 gm/liter): Maintains osmotic balance.
- Agar (5.0 gm/liter): Provides the necessary gel-like consistency.
Preparation Instructions: To prepare the medium, suspend 16.1g in one liter of distilled or deionized water. Mix thoroughly and heat with frequent agitation before sterilizing in an autoclave at 121°C (15 lbs) for 15 minutes.
Quality and Performance: The Stuart Transport Medium’s unique formulation prevents microbial proliferation while ensuring that microorganisms remain viable for an extended period. This capability has led to its recommended use for a variety of specimens. Cultural characteristics can be verified after incubation at 20-25°C for 48 hours. For optimal results, swabs should be streaked onto prepared blood agar plates.
Storage and Shelf Life: Store the dehydrated medium tightly capped at 5-30°C. It has a shelf life of 3 years from the manufacturing date. Prepared medium should be kept at 2-8°C, away from direct light.
Appearance: The dehydrated form is a free-flowing white powder, while the prepared medium appears as a milky white transparent gel.
Precautions: This product is strictly for laboratory use. Avoid using any dried medium that is past its shelf life, shows caking, or exhibits color variation.
Why Choose Stuart Transport Medium? For laboratories dedicated to high standards in diagnostic microbiology, Stuart Transport Medium provides the ultimate solution for specimen transport and preservation. Its optimized composition supports diverse organism viability, making it a critical component for effective clinical testing. With its proven performance and reliability, this medium is an indispensable tool for microbiologists aiming to achieve accurate results.
