Product Description

The plastic-base cylinder combines the precision of a glass cylinder with the durability of a plastic base. The body is manufactured from high-quality borosilicate glass 3.3 with clear, accurate graduations. The base and protective ring are made from engineering-grade plastic, offering impact resistance and tip prevention. The protective ring cushions accidental impacts, reducing the risk of glass breakage and extending product life.

Three Series · Flexible Selection

RichTech offers cylinders in round-bottom, hexagonal-bottom, and plastic-base series:

1. Round-Bottom Cylinders

Traditional round-bottom design.
Suitable for routine laboratory liquid measurement.

2. Hexagonal-Bottom Cylinders

Hexagonal base for stable, tip-resistant placement.
Ideal for high-frequency use and applications requiring extra stability.

3. Plastic-Base Cylinders

Glass body with plastic base and protective ring.
Impact-resistant and breakage-reducing — especially suitable for teaching and frequent-use environments.

Design Features

Glass Body: Borosilicate Glass 3.3 with clear, precise graduations, identical to standard glass cylinders.
Plastic Base: High-strength engineering plastic, impact-resistant, wear-resistant, and tip-resistant — protects the cylinder bottom.
Protective Ring: Wraps around the lower body to cushion impacts, reducing breakage risk and extending service life.
Clear Graduations: White or blue scale markings for quick and accurate volume reading.

Material Advantage

The body is manufactured from Borosilicate Glass 3.3 in accordance with ISO 3585 standards, with an ultra-low thermal expansion coefficient for thermal shock resistance. The base and protective ring are made from engineering-grade plastic, offering impact resistance, chemical resistance, and long-term durability.

Quality Assurance

Every piece undergoes rigorous dimensional inspection, accuracy verification, and visual inspection to meet high laboratory standards, providing reliable performance for your experiments.

Note: The plastic base and protective ring are not heat-resistant. Remove the cylinder from the base before heating. The protective ring cushions impacts but is not designed for intentional heavy drops — hidden damage may still occur.

Applications

Common Configurations

Plastic-Base Cylinder Routine liquid measurement
Pipette + Plastic-Base Cylinder Precise transfer and measurement
Beaker + Plastic-Base Cylinder Solution preparation and dispensing

Specific Applications

Teaching Labs

Basic chemistry experiments in schools and universities — frequent handling with enhanced safety

Solution Preparation

Standard solutions, buffers, culture media

Sample Measurement

Volume determination of environmental water, food, and pharmaceutical samples

Pharmaceutical Production

API preparation, intermediate testing

Chemical Analysis

Liquid measurement for raw material and product purity analysis

Food Testing

Liquid measurement for food composition analysis

Tip: The protective ring design makes plastic-base cylinders particularly suitable for teaching laboratories and frequent-use environments. The plastic base prevents tipping, while the protective ring cushions impacts and reduces breakage risk — a safe, durable choice.

Plastic-Base Cylinder Procedure

03

Preparation

Inspect the cylinder for cracks, scratches, or other defects.
Check that the plastic base and protective ring are intact and properly fitted.
Ensure the cylinder is clean and dry before use.

04

Measurement

Place the cylinder on a level surface with the base firmly in contact.
Pour liquid slowly along the inner wall to prevent liquid from running down the outer wall.
Read the volume with your eye level with the lowest point of the meniscus.
Read to the nearest 1/5 of the smallest graduation or as required by your procedure.

05

Cleaning & Maintenance

Clean immediately after use to prevent residue from drying.
Wipe the plastic base and protective ring with a soft cloth — do not use organic solvents.
Rinse with distilled water and air-dry upside down on a drying rack.
Avoid crushing or applying heavy pressure to the plastic base during storage.

Tip: The protective ring design effectively reduces breakage risk from accidental impacts, making plastic-base cylinders ideal for teaching and routine laboratory use. Clean promptly after use to prevent chemical damage to the plastic components.

Care & Notes

Safety Notes

Inspect cylinders for cracks or scratches before use — damaged glass may break during use.
Place the cylinder on a level surface for accurate reading.
The protective ring cushions impacts but is not designed for intentional heavy drops — hidden damage may occur.

Do not

Do not heat plastic-base cylinders — the plastic base and protective ring are not heat-resistant.
Handle and store with care, avoiding impact with hard surfaces.
