Product Description

Wash Bottles are specialized tools for glassware rinsing and small‑volume liquid transfer in laboratories, precision‑manufactured from borosilicate glass 3.3. The flat‑bottom design allows stable placement on the workbench without tipping, while the standard ground joint accommodates various wash bottle accessories including brushes. Suitable for daily rinsing of beakers, test tubes, graduated cylinders, and other glassware. They are essential cleaning tools in chemistry, pharmaceutical, and biology laboratories.

Key Features

Borosilicate glass 3.3: ISO 3585 compliant, thermal shock resistant to 280°C, excellent chemical resistance
Flat‑bottom design: Stable placement on the workbench — prevents tipping and ensures safe operation
Standard ground joint: Compatible with various wash bottle accessories
High clarity: Pure, transparent glass allows easy observation of contents and cleaning condition
Multiple capacities: Available in 250mL, 500mL, and 1000mL

Quality Assurance

Every unit undergoes rigorous dimensional inspection, joint fit testing, and visual examination to meet the high standards required in professional laboratories.

Note: Wash Bottles are designed for daily glassware rinsing in laboratories. Ensure the bottle is clean and dry before use. Rinse promptly after use to prevent residue buildup.

Applications

Typical Uses

Chemistry labs

Daily rinsing of beakers, test tubes, graduated cylinders, and other glassware

Pharmaceutical industry

Cleaning and pre‑treatment of production and laboratory apparatus

Biology labs

Rinsing of Petri dishes, centrifuge tubes, and other labware

Educational labs

Batch rinsing of apparatus after student experiments

Food testing

Cleaning and rinsing of apparatus during sample preparation

Compatibility Recommendations

Bottle + Wash Brush

Use with a wash brush for efficient interior cleaning

Bottle + Distilled Water

Fill with distilled water for precision apparatus rinsing

Bottle + Detergent Solution

Load with detergent for initial cleaning

Bottle + Label

Use labels to distinguish different washing applications

Tip: Wash Bottles are fundamental tools for laboratory glassware cleaning. Compared to triangular wash bottles, flat‑bottom wash bottles offer more stable placement and are ideal for benchtop operations.
