The body material of the roller mixer is usually stainless steel or high-strength plasticHere is a detailed introduction to these two materials:

stainless steel body

• advantage：

• durabilityStainless steel material has high hardness and strong impact resistance, and is not easily deformed or worn after long-term rolling friction. The service life of equipment can generally reach 5-8 years, reducing the frequency of component replacement and maintenance costs.

• high cleanlinessStainless steel has a smooth and pore free surface, which is not easy to adsorb sample residues (such as liquids and powders), and is resistant to acid and alkali corrosion (especially 316L stainless steel can withstand most chemical reagents). After the experiment, it can be cleaned by simply wiping with alcohol or water, meeting the requirements of "no cross contamination" in biological experiments (such as cell culture, nucleic acid extraction), food testing, pharmaceutical industry, etc. It can even be compatible with some sterilization processes (such as surface UV disinfection).

• Stable thermal conductivityFor temperature controlled mixing scenarios such as enzymatic reactions and constant temperature incubation, the uniform thermal conductivity of stainless steel rollers can ensure small temperature deviations (usually within ± 0.5 ℃) in various areas of the roller surface, avoiding sample temperature fluctuations caused by uneven thermal conductivity of the material and improving experimental reproducibility.

• elegant and tastefulThe stainless steel body has a beautiful appearance and improves overall quality.

• applicationDue to its material characteristics, the stainless steel roller mixer exhibits significant advantages in terms of ease of operation, applicable scenarios, safety, etc., especially suitable for experimental scenarios with high requirements for cleanliness and durability, such as life sciences, food and environmental testing, pharmaceutical industry, chemical industry, etc.

High strength plastic body

• advantage：

• lightweightHigh strength plastic material is relatively lightweight, making it easy to handle and install.

• lower costCompared to stainless steel materials, high-strength plastics may have lower costs and are suitable for laboratories or application scenarios with limited budgets.

• disadvantage：

• Relatively poor durabilityHigh strength plastics may be more prone to wear or deformation after long-term rolling friction.

• Cleanliness may be lowPlastic surfaces may be more prone to adsorbing sample residues, making cleaning slightly more difficult.

The roller mixer of Guoli Tian Company is mainly made of stainless steel body, and the old models also provide coated metal body. However, due to the defect that the coating (PTFE or powder coating) is easily peeled off, the coated version will no longer be sold in the future.
