Saline 0.85% 100mL Bottle, 1/Pk

Saline 0.85% is a sterile, isotonic solution of Sodium Chloride. This 100mL bottle serves as a versatile bulk source of sterile diluent, widely used for rinsing, washing, and preparing large-volume suspensions in the microbiological laboratory.

The 100mL "Utility" Volume: This intermediate size bridges the gap between test tubes and liter-sized bulk storage.

1. Membrane Filtration Rinse: In water and beverage testing, samples are filtered through a membrane. This 100mL volume is ideal for rinsing the filtration funnel after the sample has passed through, ensuring that any bacteria adhering to the glass walls are washed down onto the filter for accurate counting.

2. General Diluent Stock: A convenient "personal stock" for the daily workbench. Technicians can pour or pipette sterile saline from this bottle to create custom dilution volumes (e.g., 25mL or 50mL) without the risk of contaminating a large 1L supply bottle.

3. Sample Homogenization: Useful for food testing protocols where larger volumes of sterile fluid are needed to homogenize solid samples (e.g., in a stomacher bag).

The Formulation:

• Isotonic (0.85% NaCl): The solution matches the osmotic pressure of bacterial cells. This prevents osmotic shock (lysis) during rinsing or suspension, ensuring that the organisms recovered are viable and capable of growth.

• Neutral & Clear: The absence of nutrients prevents bacterial growth during processing, while the optical clarity ensures that no particulate matter interferes with filtration or microscopy.

• Filtration Essential: Perfect volume for rinsing membrane filtration units.

• Osmotic Balance: Protects cells from damage during washing steps.

• Versatile Stock: A manageable volume for custom dilutions or suspensions.

• Sterile: Ready-to-use solution eliminates prep time.

• Format: Single sterile 100mL screw-cap bottle.
