Reagent Bottle Manufacturers in India
Every laboratory — whether a school science room, a pharmaceutical QC facility, or an advanced research institute — depends on one fundamental item more than almost anything else: a reliable reagent bottle. When chemical storage, sampling accuracy, and contamination prevention are on the line, the quality of your reagent bottle is not a detail — it is the foundation.
Viscilabs has been one of India’s most trusted reagent bottle manufacturers since 1976. Based in Ambala Cantt, Haryana — India’s most storied hub for scientific instrument manufacturing — we produce a comprehensive range of laboratory-grade reagent bottles in borosilicate glass, designed to meet the exacting standards of modern laboratories across research, education, pharma, chemical, and industrial sectors.
As an ISO 9001:2015 Certified company with nearly five decades of manufacturing heritage and a global export footprint, Viscilabs brings you reagent bottles that don’t just hold chemicals — they protect the integrity of your science.
What Is a Reagent Bottle?
A reagent bottle is a type of laboratory glassware specifically designed for the storage, preparation, and dispensing of chemical reagents, solutions, and samples. They are manufactured in borosilicate glass for superior chemical resistance, thermal stability, and durability compared to soda-lime glass.
Reagent bottles come in a variety of configurations — narrow mouth, wide mouth, clear glass, amber glass, screw cap, hollow stopper, and interchangeable stopper — each suited to different storage requirements and chemical types. Choosing the right reagent bottle configuration is critical to maintaining sample purity, preventing evaporation or contamination, and ensuring safe handling in the laboratory.
Our Reagent Bottle Product Range
At Viscilabs, we manufacture and supply a complete range of reagent bottles to meet every laboratory requirement. Each bottle is produced from quality borosilicate glass and finished to precise dimensional tolerances.
Bottle Reagent — Narrow Mouth, Screw Cap, Clear (Type: GW1110)
Our clear narrow-mouth reagent bottles with screw caps are ideal for the storage of liquid reagents where a secure, leak-proof closure is required. The narrow mouth minimises evaporation and the risk of spillage during dispensing. The screw cap provides an airtight seal suitable for routine storage of aqueous solutions, solvents, and diluted acids.
Available in a range of capacities to suit small-volume samples through to bulk reagent storage.
Bottle Reagent — Plain Narrow Mouth (Type: GW1109)
The plain narrow-mouth reagent bottle is a laboratory classic — a straightforward, versatile storage vessel for liquid reagents that do not require a specialised closure. Compatible with standard ground glass stoppers, it is widely used across teaching laboratories and general chemical storage applications.
Bottles — Reagent, Amber, Wide Mouth, Screw Cap (Type: GW1112)
Light-sensitive chemicals — including many biological stains, photochemicals, and reactive compounds — require amber glass to prevent photodegradation. Our amber wide-mouth reagent bottles with screw caps offer broad-opening access for easy filling and pipetting, combined with the UV-protection properties of amber borosilicate glass.
Ideal for pharmaceutical, biological, and chemical laboratories storing light-sensitive solutions.
Reagent Bottle — Hollow Stopper, Narrow Mouth, Amber (Type: GW1116)
This specialised amber reagent bottle features a hollow interchangeable stopper — designed for applications where precise dispensing and airtight sealing are equally important. The hollow stopper allows for controlled pouring while the amber glass protects photosensitive contents. Widely used in analytical and pharmaceutical laboratories for storing indicator solutions and sensitive reagents.
Bottles — Interchangeable Stopper (Type: GW1118)
Our range of reagent bottles with interchangeable ground glass stoppers provides the gold standard of chemical sealing for laboratory use. The precision-ground stopper-and-neck fit ensures a vapour-tight closure with no degradation from chemical contact — essential for volatile solvents, concentrated acids, and hygroscopic reagents. Available in both clear and amber glass.
Bottle — B.O.D. (Type: GW1104)
Our Biochemical Oxygen Demand (B.O.D.) bottles are a specialised form of reagent bottle used for environmental and water quality testing. Manufactured to standard specifications, they feature a ground glass stopper for a water-sealed closure that prevents atmospheric oxygen from interfering with the sample during incubation.
Dropping Bottle With Rubber Teat — Clear (Type: GW1105)
Designed for controlled drop-by-drop dispensing of reagents, our clear dropping bottles with rubber teats are widely used in teaching laboratories and analytical work. The integrated rubber teat allows precise, single-drop dispensing without the need for additional pipettes.
Dropping Bottle With Rubber Teat — Amber (Type: GW1106)
The amber version of our dropping bottle provides light protection for photosensitive indicator solutions and reagents used in titrations, spot tests, and qualitative analysis. A staple of school and college chemistry laboratories.
Specific Gravity Bottle With Ground Capillary Stopper (Type: GW1111)
Also known as a pycnometer, this precision bottle is used for the determination of specific gravity and density of liquids. The ground capillary stopper ensures accurate volume definition. Manufactured to close tolerances for reliable, reproducible density measurements.
Weighing Bottle — Squat Form (Type: GW1113)
Weighing bottles are used for the accurate weighing of hygroscopic substances and other chemicals in analytical laboratories. The squat form provides a low centre of gravity for stability on the balance pan, while the ground glass stopper ensures an airtight seal during weighing operations.
McCartney Bottle — Narrow Mouth (Type: GW1107) & Wide Mouth (Type: GW1108)
McCartney bottles are small, flat-sided screw-cap bottles widely used in microbiology for culture media, sample storage, and serial dilutions. We supply both narrow-mouth and wide-mouth variants in borosilicate glass — autoclavable and chemically resistant for sterile laboratory workflows.
Materials & Manufacturing Standards
All Viscilabs reagent bottles are manufactured from borosilicate glass — the material of choice for laboratory glassware worldwide. Borosilicate glass offers:
- Excellent resistance to thermal shock (withstands rapid temperature changes without cracking)
- Superior chemical inertness — resistant to acids, alkalis, and solvents
- Low coefficient of thermal expansion — dimensional stability across temperature ranges
- Clarity and optical transparency for content visibility (clear glass variants)
- UV light attenuation to protect photosensitive contents (amber glass variants)
Our manufacturing process adheres to ISO 9001:2015 quality management standards, with every batch subject to dimensional inspection, wall thickness verification, and stopper fit testing before dispatch.

Quality Assurance — Our Process
At Viscilabs, quality isn’t a final checkpoint — it’s built into every stage of production.
Raw Material Qualification: We use verified borosilicate glass stock meeting specified composition and purity requirements.
Dimensional Inspection: Neck diameter, bore diameter, overall height, and wall thickness are checked against product specifications.
Stopper Fit Testing: All ground glass stopper bottles are tested for correct fit and airtight seal before packaging.
Annealing Verification: Proper annealing eliminates internal stresses in the glass — a critical step that determines thermal shock resistance and long-term durability.
Packaging: Bottles are carefully packaged to prevent transit damage — particularly important for high-precision items like specific gravity bottles and weighing bottles.
