Description
Product Overview
The Kimble Chase Lab Weighing Bottle (model M3682) is a precision‑engineered glass vessel designed for laboratory weighing applications, especially butter‑fat content testing. Constructed from high‑quality borosilicate glass, the bottle features a permanent brown‑stained scale that is calibrated for a 9 g sample, where 5 ml represents 50 % of the sample volume. The neck is positioned on one side of the body, creating a large opening that facilitates the addition of solid or viscous materials directly into the bottle. Package dimensions are 8.3 × 4.1 × 2.8 inches and the weight is 10.4 oz, making it easy to handle while maintaining durability.
Usage
This bottle is ideal for analytical laboratories, food science labs, and research facilities that require accurate measurement of butter‑fat or similar lipid content. The wide opening allows technicians to introduce butter, cream, or other semi‑solid samples without spillage, while the calibrated scale provides quick visual reference for sample weight. The three supplied rubber stoppers create an airtight seal, preventing oxidation or contamination during analysis. 
Why Choose Us
Kimble Chase is a trusted name in laboratory glassware, known for rigorous quality control and consistent performance. Each bottle undergoes a thorough inspection to ensure the permanent scale remains legible and the glass is free from defects. The etched vertical line, centered in a contrasting dark band, aids precise placement of calipers, reducing measurement error. Our commitment to durability means the bottle resists thermal shock and chemical exposure, extending its service life in demanding lab environments.

FAQ
What sample size can the bottle accurately measure?
The bottle is calibrated for a 9 g sample, with the scale indicating 5 ml as 50 % of the sample volume, providing reliable measurements for typical butter‑fat analyses.
Can the bottle be used with liquids other than butter?
Yes, the wide opening and chemical‑resistant glass make it suitable for a variety of viscous or solid samples, including oils, creams, and semi‑solid reagents.
How do the rubber stoppers ensure sample integrity?
The three supplied rubber stoppers create an airtight seal, preventing oxidation, evaporation, or contamination during storage or measurement.
Is the permanent scale affected by cleaning solvents?
The brown‑stained scale is designed to withstand standard laboratory cleaning agents without fading, ensuring long‑term readability.
What is the best way to align the calipers with the etched line?
Place the caliper tip against the etched vertical line within the contrasting dark band; this visual cue ensures consistent positioning for repeatable measurements.
