Crystal Laboratory Beakers TEKA model 608688 — laboratory glassware set

Laboratory crystal glass beakers from TEKA model 608688 are precision glassware designed for routine experiments, mixing, measuring and gentle heating in analytical, educational and quality control laboratories. Made of clear crystal glass, these beakers offer good chemical resistance and excellent visibility of samples, supporting accurate observation during sample preparation and general laboratory workflows.

Advantages

These crystal glass beakers provide stable dimensional accuracy and a smooth surface that is easy to clean, reducing the risk of contamination between experiments. The clear material improves visual monitoring of reactions and volume levels. Their uniform wall thickness ensures reliable thermal behavior for common laboratory heating tasks and steady handling during transfers and measurements.

Suitable for

• Mixing and preparing chemical solutions in analytical and educational settings
• Measuring approximate liquid volumes during routine procedures
• Sample preparation prior to analysis or titration
• General-purpose heating with appropriate laboratory heating equipment
• Teaching demonstrations and student laboratory exercises

Key specifications

• Material: clear crystal glass with good chemical resistance
• Design: straight-sided beaker shape with pour spout for controlled pouring
• Visibility: high optical clarity for observation of contents
• Cleaning: smooth surface suitable for routine cleaning and drying
• Use environment: suitable for analytical, educational and general laboratory use

How to use

Before first use, inspect each beaker for chips or cracks and clean with appropriate laboratory detergent and distilled water. Use the beaker for mixing, dissolving or holding liquids; read approximate volumes from the graduation marks if present, but rely on calibrated glassware for precise volumetric measurements. When heating, place the beaker on recommended heating equipment such as a hotplate or sandbath and avoid direct flame contact unless the manufacturer states otherwise. Handle with appropriate personal protective equipment and use tongs or thermal gloves for hot beakers.

Usage recommendations

Use these beakers for routine laboratory tasks where clear visibility and chemical resistance are required. Avoid sudden temperature shocks, strong alkaline or hydrofluoric acid exposure without confirmation of material compatibility, and replace any beaker that shows damage to maintain safety and measurement integrity.
