Imprecise glassware breaks experiments before they start. When your beaker graduates read inconsistently or chip under routine autoclave cycles, every downstream result is suspect. The SIBATA 10020 Series Borosilicate Glass Beaker is engineered from high-purity borosilicate tubing manufactured in Germany — the same material trusted in research-grade labware worldwide. The low-form Griffin profile delivers a wide, stable base for stirring and heating, while the precision-fired easy-pour spout lets you transfer liquids cleanly without reaching for a funnel. White-fired graduation markings are permanent — they will not wash off, fade under UV, or obscure when wet.Features and Benefits German-manufactured borosilicate glass: Produced in Germany from Type 1 borosilicate tubing with a low coefficient of thermal expansion (3.3 × 10⁻⁶/K), making these beakers highly resistant to thermal shock during heating, cooling, and autoclave cycles. Autoclavable for sterile workflows: The full size range withstands standard autoclave conditions (121°C / 250°F, 15 psi, 20-minute cycle) without distortion, delamination, or loss of graduation accuracy — essential for media preparation and sterile reagent handling. ±5% graduation accuracy across the full range: White-fired graduations are precision-fired into the glass surface — not printed, not applied as a decal. Accuracy is ±5% of full capacity, meeting the practical measurement needs of general laboratory procedures. Low-form Griffin profile with uniform wall thickness: The classic low-form (Griffin) design provides a wide, stable base that resists tipping on crowded benchtops. Uniform wall thickness ensures even heat distribution when placed on hot plates or over open flame. Full size range from 50mL to 3000mL: Eight volumes in one product family let you standardize on a single trusted brand across your entire beaker inventory — from small-scale reagent mixing at 50mL up to large-batch media preparation at 3000mL. Broad chemical resistance: Borosilicate glass resists attack from most acids, bases, and organic solvents encountered in routine laboratory work, including hydrochloric acid, sodium hydroxide solutions, ethanol, acetone, and aqueous buffer systems. 1-year manufacturer warranty: Each beaker is backed by a 1-year warranty from SIBATA, reflecting the quality controls built into every production run.

The autoclavable borosilicate construction handles repeated sterilization cycles without degradation. Chemical synthesis and reagent mixing: Uniform wall thickness and broad chemical resistance make the 50mL–300mL sizes a reliable choice for small-scale synthesis, titration setups, and preparing reagent stocks in chemistry and analytical labs. Educational and teaching laboratories: The pack-of-10 quantities (50mL–500mL) are well-matched to classroom lab settings where multiple students work simultaneously. Durable construction reduces breakage-related replacement costs over a semester. Cell culture and biological buffer preparation: The transparent glass allows visual inspection of clarity and color change during buffer preparation and pH adjustment. Compatible with magnetic stir bars for continuous mixing without contamination risk. Quality control and analytical testing: The 100mL and 200mL sizes are frequently used as collection vessels in titration workflows, dissolution testing, and gravimetric analysis where precise liquid handling and chemical inertness are required. Frequently Asked QuestionsAre the SIBATA 10020 Series beakers autoclavable?Yes. The full size range — 50mL through 3000mL — is rated for standard autoclave conditions at 121°C (250°F), 15 psi, for 20-minute cycles. Borosilicate glass withstands repeated sterilization without softening, warping, or losing graduation legibility.How many beakers come in a pack for each size?50mL, 100mL, 200mL, 300mL, and 500mL come in packs of 10. The 1000mL size comes in a pack of 6. The 2000mL and 3000mL sizes are sold individually (1 each). All pricing shown is per pack or per unit as specified.What is the graduation accuracy of these beakers?Graduations are accurate to ±5% of full capacity. For example, on a 100mL beaker, readings are accurate to within ±5mL at the 100mL mark. This is standard for general-purpose Griffin beakers and meets the requirements of most research, teaching, and QC applications. For volumetric precision work, complement with a SIBATA Class A volumetric flask.Can I heat these beakers directly on a hot plate or over a Bunsen burner?Yes. The uniform wall thickness and low thermal expansion coefficient of borosilicate glass make these beakers suitable for direct heating on ceramic-top hot plates and open flame (with a wire gauze support over a Bunsen burner). Avoid placing cold beakers directly on a hot surface — allow gradual temperature equilibration to prevent thermal shock.Where are these beakers manufactured?SIBATA 10020 Series beakers are manufactured in Germany from high-purity borosilicate tubing. They carry a 1-year manufacturer warranty covering defects in materials and workmanship.Quality AssuranceSIBATA Scientific Technology has manufactured precision laboratory glassware since 1932. The 10020 Series beakers are produced in Germany from borosilicate tubing meeting ASTM E438 Type I, Class A material standards, under SIBATA's ISO 9001-certified quality management system. Each production batch undergoes dimensional inspection and graduation verification before shipment.As an authorized dealer, we ship directly from USA inventory.
