Globe Scientific Sternheimer Malbin Urine Sediment Stain, 50 mL Dropper Bottle, 1/Pack
The Globe Scientific Sternheimer Malbin Urine Sediment Stain is a ready-to-use supravital reagent for enhancing the microscopic visualization of cells, casts, and crystals in urine sediment. Lab technologists rely on this stain for manual urinalysis, sediment cytology, and differentiation of leukocytes, epithelial cells, and renal casts that are difficult to resolve in unstained wet mounts.

Frequently Asked Questions
Is this stain ready to use or does it require dilution?
The Sternheimer-Malbin stain ships as a ready-to-use working reagent. Add a drop to resuspended urine sediment per your lab's validated procedure; no further dilution is required for routine microscopy.
How is the stain dispensed?
Each 50 mL bottle features a dropper-style cap for controlled drop-by-drop addition to sediment preparations, minimizing waste and over-staining during manual urinalysis.
What cellular elements does this stain enhance?
This supravital formulation improves contrast on leukocytes, epithelial cells, and renal casts, and aids differentiation of glitter cells. Crystals and red cells are also more readily distinguished from artifacts.
How should the stain be stored?
Store at room temperature away from direct light and tightly capped between uses. Refer to the product label and SDS for shelf life and handling guidance specific to your lot.
