Pyrex Conical Flask 1000 ml High-Borosilicate Glass Narrow Neck Erlenmeyer Flask

Pyrex Conical Flask 1000 ml High-Borosilicate Glass Narrow Neck Erlenmeyer Flask

Premium Technical Glassware Designed for demanding Laboratory Applications in BD Pyrex Conical Flask 1000 ml

Modern scientific research and industrial testing in Bangladesh demand equipment that guarantees zero sample contamination, structural integrity, and long-term durability. Whether utilized in the pharmaceutical manufacturing hubs of Dhaka, environmental research institutes in Chittagong, or textile testing facilities in Gazipur, the Pyrex Conical Flask 1000 ml meets global laboratory testing standards (ISO 1773 / ASTM E1404). Its precision craftsmanship makes it an indispensable tool for liquid measurement, chemical synthesis, heating operations, and biological culture growth.

Key Technical Attributes & Architectural Benefits

1. Low Expansion Borosilicate 3.3 Composition

The Pyrex Conical Flask 1000 ml is constructed from high-purity borosilicate glass featuring an ultra-low linear coefficient of thermal expansion ($3.3 \times 10^{-6}/\text{K}$). This specialized glass matrix gives the flask incredible structural resilience, allowing it to withstand severe thermal shocks ($\Delta T = 100\text{ K}$) and high-temperature direct heating without cracking, stress fracturing, or exploding.

2. Optimized Erlenmeyer Geometry for Lab Safety Pyrex Conical Flask 1000 ml

• Vigorous Swirling Without Spills: The sloped conical walls channel liquids downward, enabling technicians to mix reagents, dissolve solutes, or perform manual titrations energetically without risking liquid spillage through the neck.

• Heavy-Duty Beaded Rim: The narrow neck features a machine-finished, reinforced beaded lip. This structural reinforcement prevents chipping during routine handling, cleaning, or insertion of glass funnels and rubber stoppers.

• Hermetic Seal Capability: Designed with a uniform narrow neck diameter that fits standard rubber stoppers (Size No. 8 or No. 9), allowing for airtight liquid storage, gas trapping, or incubation setups.

3. Permanent Fired Enamel Scale & Labeling Spot Pyrex Conical Flask 1000 ml

• High-Contrast Measurement: The outer body features high-contrast white ceramic enamel graduations marking $200\text{ ml}$ to $1000\text{ ml}$ intervals. The scale is baked into the glass at extreme temperatures, ensuring it will not rub off or fade even after prolonged exposure to acid baths or ultrasonic cleaning.

• Marking Patch: Includes a large, textured ceramic writing area designed for clean labeling using standard laboratory markers.

4. Absolute Chemical Purity & Sterilization Readiness Pyrex Conical Flask 1000 ml

Pyrex borosilicate glass is non-porous and chemically inert. It offers near-total resistance against neutral solutions, strong acids, organic solvents, and corrosive chemicals. Crucially, it prevents sodium or metal ion leaching into sensitive media. The flask can easily withstand repeated steam sterilization cycles and is 100% autoclavable at $121^\circ\text{C}$ ($15\text{ psi}$).

Why Upgrade to Authentic Pyrex Laboratory Glassware?

In many testing environments across Bangladesh, cheap generic glass vessels lead to frequent thermal cracks, chipped rims, and costly replacement cycles. Investing in an authentic Pyrex Conical Flask 1000 ml ensures uniform wall thickness distribution, superior thermal shock tolerance, and maximum physical durability. This drastically lowers overall lab operational costs and enhances user safety during high-temperature procedures.

Care and Maintenance Guidelines Pyrex Conical Flask 1000 ml

1. Even Heat Distribution: When heating liquids over an open Bunsen burner flame, always place a ceramic-centered wire gauze on the tripod stand to distribute heat evenly across the flat bottom of the flask.

2. Prevent Thermal Shock: Never transfer a hot flask directly onto cold stainless steel countertops or wet stone surfaces; always rest it on an insulated wooden or silicone heat pad.

3. Cleaning Protocol: Wash using mild laboratory detergent and soft nylon brushes. Avoid abrasive scouring pads that can scratch the protective interior glass surface.

7. Frequently Asked Questions (FAQ)

Q1: What is the price of a Pyrex Conical Flask 1000 ml in Bangladesh?

A: Depending on single retail purchases or bulk institutional lab contracts, the price generally ranges between BDT 450 to BDT 650 per piece in local scientific market outlets.

Q2: Can this Pyrex 1000 ml conical flask be heated directly on a gas burner?

A: Yes. Because it is manufactured from authentic low-expansion borosilicate 3.3 glass, it can safely withstand direct liquid heating over hot plates, alcohol lamps, or gas burners (using a wire gauze pad).

Q3: Is the Pyrex Conical Flask 1000 ml autoclavable for biological research?

A: Yes, Pyrex borosilicate glass flasks are fully autoclavable and steam sterilizable at $121^\circ\text{C}$ for media preparation and biological testing.

Q4: What rubber stopper size fits a 1000 ml narrow neck conical flask?

A: A standard No. 8 or No. 9 rubber stopper (or a 37 mm top opening plug) fits the narrow neck securely.

Q5: How accurate are the measurement lines on a conical flask?

A: Conical flasks are designed for liquid mixing, reaction containment, and approximate volume estimation (typically within $\pm5\%$ accuracy). For precise volumetric measurement, use a Class A volumetric flask or graduated cylinder.1
