Product Description

The handled beaker is a versatile laboratory vessel designed with an integrated handle for safer handling during heating and pouring. Manufactured from borosilicate glass 3.3 (ISO 3585), it exhibits excellent thermal shock resistance (up to 280°C) and chemical durability.

Key Features

Integrated Handle: Molded as one piece, sturdy and comfortable, reduces burn risk
Borosilicate 3.3: Standard material; optional high-quality 3.3 upgrade
Thermal Stability: Withstands rapid temperature changes
High Clarity: Easy observation of contents
Wide Size Range: 50ml to 2000ml
Spout: Facilitates clean pouring

Material Note: Standard material is low-borosilicate glass. Upgrade to Borosilicate 3.3 is available upon request for enhanced performance.

Operation & Maintenance

User Guide

Before Use

Inspect for cracks, bubbles or loose handle
Wash with mild detergent, rinse 3 times with distilled water
Sterilize by dry heat (160°C, 2h) or autoclave (121°C, 20min)

Heating

Use wire gauze to distribute heat evenly
Do not fill more than 2/3 capacity to avoid boiling over
Use heat-resistant gloves when handling hot beakers
Cool slowly; never quench

Stirring & Transfer

Use glass rods; avoid impact with hard objects
Pour using the spout to prevent drips

Cleaning & Storage

Clean immediately after use
Soak in dilute nitric acid for stubborn residues
Rinse with distilled water and air-dry upside down
