# BIOLAB Lugol’s Iodine 100ml | Laboratory Staining Reagent

## BIOLAB Lugol’s Iodine 100ml – Professional Laboratory Staining Reagent

**BIOLAB Lugol’s Iodine** is a professional laboratory iodine reagent supplied in a **100 mL pack** for validated microscopy, bacteriology and staining procedures where Lugol’s iodine is specified.

BIOLAB includes Lugol’s Iodine within its bacteriology-stain range and identifies the product for **Gram & FVG staining and other laboratory applications**.

Lugol’s iodine is an aqueous iodine-based laboratory solution traditionally prepared using iodine and potassium iodide. Exact concentration, composition and analytical specifications for the supplied BIOLAB batch must be taken from the current manufacturer label or technical documentation rather than assumed from generic Lugol formulations.

**Professional laboratory use only.** Specimen preparation, staining sequence, reagent exposure time, dilution where applicable, washing, microscopy, quality control and interpretation must follow the current BIOLAB instructions and the laboratory's validated SOP.

## What Is Lugol’s Iodine?

Lugol’s iodine is an aqueous iodine solution traditionally based on **iodine and potassium iodide in water**.

The potassium iodide helps iodine remain dissolved in the aqueous solution, producing an iodine-containing reagent suitable for a variety of professional laboratory applications.

However, Lugol formulations can differ between manufacturers and intended applications.

**Do not assume that every Lugol’s iodine product has the same iodine concentration.** Where reagent concentration is critical, use the current BIOLAB bottle label, package insert or Certificate of Analysis.

* * *

## What Is BIOLAB Lugol’s Iodine Used For?

BIOLAB identifies Lugol’s Iodine for professional staining and bacteriology applications including:

-   Validated Gram staining procedures
-   Manufacturer-listed FVG staining applications
-   Professional microscopy staining workflows
-   Selected laboratory iodine-staining procedures
-   Teaching and demonstration laboratory procedures
-   Other procedures where the method specifically specifies Lugol’s iodine

The exact application, concentration and exposure time depend on the laboratory method being followed.

* * *

## Lugol’s Iodine in Gram Staining

Iodine solutions are used as a **mordant** in conventional Gram-staining workflows.

In a typical Gram-stain sequence:

1.  A prepared and fixed microbial smear is treated with the primary stain.
2.  An iodine reagent is applied as the mordant.
3.  A decolourisation step follows.
4.  A counterstain is applied.
5.  The slide is examined microscopically.

The iodine stage helps form and stabilise the primary dye–iodine complex within appropriately stained organisms.

**Important:** Do not automatically substitute Lugol’s iodine for a dedicated Gram’s Iodine reagent unless your laboratory SOP or BIOLAB instructions specifically permit that use. BIOLAB lists **Gram’s Iodine and Lugol’s Iodine as separate products**, even though Lugol’s Iodine may have Gram-staining applications.

* * *

## BIOLAB Lugol’s Iodine vs Gram’s Iodine

| Feature | Lugol’s Iodine | Gram’s Iodine |
| --- | --- | --- |
| **Product Identity** | General iodine / potassium iodide laboratory reagent formulation | Dedicated Gram-staining iodine reagent |
| **BIOLAB Lists Separately?** | Yes | Yes |
| **Gram-Stain Application** | Manufacturer lists Gram staining among applications | Specifically intended for Gram staining |
| **Interchangeable?** | **Do not assume interchangeability.** Follow the exact validated staining procedure. |     |

* * *

## Lugol’s Iodine in Microscopy

Iodine solutions can be useful in microscopy because iodine can increase contrast in selected biological structures.

Professional laboratory procedures may use iodine staining to help visualise structures that otherwise have limited contrast under bright-field microscopy.

For example, appropriately prepared iodine solutions have historically been used in wet-mount parasitology to enhance visualization of selected protozoan cyst structures.

**Do not automatically use full-strength BIOLAB Lugol’s Iodine for stool wet mounts.** Some parasitology methods require a specifically diluted iodine preparation, and the exact formulation must follow the validated laboratory SOP.

* * *

## Lugol’s Iodine for Stool / Parasitology Microscopy

Lugol-type iodine solutions are used in certain professional parasitology microscopy methods for staining structures within protozoan cysts.

In appropriately prepared specimens, iodine staining can increase contrast of features such as:

-   Glycogen material
-   Cytoplasmic structures
-   Nuclear structures
-   Selected internal cyst features

However, strong iodine preparations may need to be diluted for some wet-mount methods.

**The BIOLAB 100 mL product should therefore be used for parasitology only where your validated SOP specifies this product or an appropriate Lugol formulation and concentration.**

* * *

## Microscope Slides for Laboratory Staining

Correct microscopy begins with an appropriately prepared specimen on a clean slide.

Microsidd supplies [**Microscope Glass Slides**](https://microsidd.com/products/microscope-glass-slides) for microbiology, haematology, pathology and other laboratory microscopy procedures.
