Lithium L-Lactate TCI L0144

Lithium L-Lactate is the lithium salt of L-lactic acid, the lactate enantiomer recognised by the enzyme systems of living organisms. Presenting lactate in salt form makes the compound a solid that is straightforward to weigh out and readily soluble in water, which is far more practical in daily bench work than liquid lactic acid, a material that is hygroscopic and sticky to handle. In the laboratory, it serves as a measured source of lactate for enzymatic assays, for preparing standard solutions in lactate determination, and as a supplement in cell and microbial culture media.

The property that governs its selection is stereochemical purity at the L position, which matters because lactate dehydrogenase acts specifically on one enantiomer, so the identity of the isomer supplied determines whether the assay responds at all. Good solubility in water allows concentrated stock solutions to be prepared without resorting to organic solvents, simplifying both formulation and downstream handling. The lithium cation is comparatively non-interfering across many enzymatic systems at the concentrations normally used in practice. As a solid salt, the material is also more stable during storage than the corresponding free acid, though it still needs protection from humidity so that it does not take up water and cake.

In Indonesian laboratories, this compound is used widely in clinical biochemistry and in related analytical and research settings where lactate must be introduced or quantified reliably. Working conditions across the region often combine warm ambient temperatures with high relative humidity, so the convenience of a weighable, water-soluble solid is a practical advantage for routine bench preparation, for teaching and research laboratories, and for facilities that prepare their own calibration and culture solutions in house.

• Enzymatic assay substrate: provides a defined L-lactate source for lactate dehydrogenase based reactions, where the enzyme's specificity for the L enantiomer makes stereochemical identity essential to a valid response.
• Standard solution preparation for lactate determination: the solid salt can be weighed accurately and dissolved in water, giving reproducible reference concentrations for calibrating lactate measurement procedures.
• Cell culture media supplementation: serves as an added lactate component in culture formulations, dissolving readily in aqueous media without requiring organic solvents that could affect cell viability.
• Microbial culture media supplementation: supplies lactate to microbiological growth media, with the salt form offering easier handling and dosing than viscous, hygroscopic free lactic acid.
• Clinical biochemistry work: supports laboratory procedures in clinical biochemistry that depend on a stable, well defined lactate source for method preparation and routine analytical use.

• Product code: L0144

Store the container tightly closed in a cool, dry place, away from moisture, since the material can absorb water and cake if left exposed to humid air. Keep it in its original tightly sealed container or transfer to a clean, well sealed vessel with a secure closure; a desiccated storage cabinet is helpful in humid conditions. Use clean, dry spatulas and weighing vessels to avoid introducing moisture or contamination into the bulk material, and close the container promptly after each use. Handle in a well ventilated area using standard laboratory personal protective equipment, including a lab coat, safety glasses, and gloves, and avoid generating or inhaling dust during weighing. Label all prepared solutions clearly and follow institutional procedures for chemical handling and waste disposal.
