Plastic measuring cylinder

Introduction to Plastic measuring cylinder

Plastic measuring cylinders are liquid volume measuring instruments made from polymer materials, serving for measuring and pouring solutions and chemicals in the laboratory. Compared to glass, plastic measuring cylinders reduce the risk of breakage upon impact while offering excellent chemical resistance. This line of instruments is typically manufactured to meet metrological standards such as ISO 6706, DIN 12681, or BS 5404 with class A or class B accuracy, depending on testing requirements.

When choosing plastic measuring cylinders, users should consider the construction material, tolerance class, and thermal tolerance of the working process. Polypropylene (PP) plastic can be autoclaved at 121 °C and used continuously at 100 °C, while PMP (TPX) plastic features high transparency and can withstand temperatures up to 170 °C. The graduations also vary, with embossed or printed blue/white markings for easy liquid level observation. Hoa Viet currently distributes plastic measuring cylinders from Vitlab (Germany) and Aptaca (Italy), meeting diverse research and analytical needs.

What is the difference between PP and PMP plastic measuring cylinders?

PP measuring cylinders made of polypropylene feature good chemical resistance, withstand autoclave temperatures up to 121 °C, and continuous operation at 100 °C. PMP (TPX) measuring cylinders offer superior transparency and higher temperature resistance, up to 170 °C.

How do the tolerances of class A and class B plastic measuring cylinders differ?

Class A cylinders have stricter error limits according to DIN 12681 and ISO 6706 standards, used for measurements requiring high precision. Class B cylinders have a wider permissible tolerance range, suitable for general quantitative tasks.

What should be noted when cleaning plastic measuring cylinders to avoid damaging the graduation marks?

For graduated plastic measuring cylinders, users should not wash or clean them at temperatures exceeding 60 °C. Adhering to this temperature helps preserve the durability and clarity of the scale over time.
