Product Description
Aquastar® CombiTitrant 5 Karl Fischer Reagent
Aquastar® CombiTitrant 5 (Supelco / Merck) is a globally recognized one-component reagent designed for volumetric Karl Fischer titration. Formulated for the direct quantification of moisture in solid, liquid, and gaseous samples, it contains all active chemical components—iodine, sulfur dioxide, and an innovative non-toxic organic base—dissolved together in an alcohol-based medium. With a nominal water equivalency of approximately 5 mg of water per milliliter of reagent (titer ~ 5 mg H2O/mL), it delivers rapid reaction kinetics and razor-sharp electrochemical endpoints for analytical laboratories across Bangladesh.
Controlling trace moisture is essential in pharmaceutical manufacturing, transformer oil testing, food processing, and chemical synthesis. Moisture in active pharmaceutical ingredients (APIs) and finished tablets leads to chemical degradation, reduced shelf life, and failed stability batches. In dielectric oils, water triggers catastrophic electrical breakdown. Aquastar® CombiTitrant 5 eliminates measurement uncertainties by offering exceptional titer stability and minimal drift over time, ensuring audit-proof compliance with international pharmacopeial protocols (USP <921>, Ph. Eur. 2.5.12).
Unlike traditional Karl Fischer reagents that contain toxic, foul-smelling pyridine, Aquastar® CombiTitrant 5 utilizes non-hazardous imidazole derivatives. This modern formulation provides a safer working environment for laboratory chemists while accelerating the titration reaction rate. It integrates seamlessly with all automated volumetric Karl Fischer titrators (such as Metrohm, Mettler Toledo, Hanna, and SI Analytics) when paired with standard titration solvents like Aquastar® CombiMethanol or CombiSolvent. Victor Scientific Co. supplies original, certified Aquastar® reagents with lot-specific certificates of analysis (CoA) and nationwide delivery across Bangladesh.

Frequently Asked Questions (FAQ)
A1
The price of Aquastar® CombiTitrant 5 (1 Liter bottle) in Bangladesh typically ranges between BDT 14,000 and BDT 22,000 per bottle, depending on import shipment batches, currency exchange rates, and order volume. Contact Victor Scientific Co. directly for real-time stock pricing and institutional quotes.
Q2
What is the difference between a one-component and two-component Karl Fischer reagent?
A2
In one-component reagents like CombiTitrant 5, all reactants (iodine, sulfur dioxide, and base) are contained in the titrant bottle, while the titration cell contains an alcoholic solvent like methanol. In two-component systems, the titrant contains only iodine in solvent, while the solvent cell contains sulfur dioxide and base. One-component reagents offer greater operational flexibility and easier inventory management.
Q3
How do I standardize the titer of CombiTitrant 5?
A3
The titer should be determined using a primary standard, such as certified Water Standard 1% (10 mg/g) or high-purity disodium tartrate dihydrate. Inject a known mass into the dry cell and calibrate the titrator buret to obtain the exact titer in mg H2O/mL.
Q4
Which solvent should be used in the titration vessel with CombiTitrant 5?
A4
CombiTitrant 5 is typically paired with Aquastar® CombiMethanol (for general polar samples) or CombiSolvent (methanol-free for aldehydes and ketones) to achieve optimal dissolution and stoichiometric reaction rates.
Q5
Does Victor Scientific Co. ship hazardous chemical reagents outside Dhaka?
A5
Yes, all reagent bottles are factory-sealed, enclosed in secondary impact-resistant chemical packaging, and delivered safely to pharmaceutical zones and industrial plants in Gazipur, Savar, Chattogram, Sylhet, and Cumilla via dedicated chemical transport services.
