Sustainability

Sustainability is one of our 3 core values and we follow multiple strategies to increase circularity of our lab instruments and consumables. Here are some examples:

  • Reduce: We are reducing the amount of packaging materials where possible. For example, the packaging size of the Sartolab® RF|BT 150-250 ml product variants was reduced between 11% (cardboard packaging) and 22% (plastic packaging film).
  • End-of-Life and Recyclability: To enable high recycling rates, our instruments are typically easy to disassemble. For example, the Quintix® Pro lab balance avoids using restrictive technologies, like adhesives, to simplify the recycling process.
  • The Optifit Tip Refill Tower offers a variety of tip volumes in a space-saving package for a wide range of laboratory applications. It reduces plastic consumption and logistics emissions. In addition, the Refill Tower packaging has earned the ACT label.

Frequently Asked Questions

Proper sample preparation is crucial for minimizing variability, enhancing detection sensitivity, and strengthening the credibility of scientific research. It ensures that samples are reproducible and precise, leading to accurate and reliable experimental results.

Remember to use filtered tips to minimize cross contamination risk, and utilize reverse pipetting mode for viscos liquids to improve accuracy and repeatability. 

Typically creating larger batch of master mix is more efficient and can improve the repeatability of assays.

For more tips, see Pipetting Academy Sample Preparation module.

Sartorius filtration products, such as Minisart® syringe filters and Sartolab® vacuum filtration units, are designed for precise particle removal and sterile filtration. 

They help achieve accurate and reproducible results by removing impurities and ensuring sample sterility.

Sartorius enhances the sensitivity and specificity of molecular biology assays with high-quality sample preparation solutions, including ultrafiltration devices, ultrapure water systems, and extraction kits

These products allow for the detection of low-abundance targets and ensure reliable results.

For critical analyses in analytical research where a low organic content is required (e.g. HPLC or ICP-MS), a water purification system that includes a UV-lamp is needed. After the UV-lamp, a deionization cartridge is needed to remove the ions that have been oxidized. 

Additionally, it is highly recommended to use activated carbon because of its high surface area and adsorption properties that allow it to efficiently remove organics from the product water. 

This is usually achieved by using a mixed bed resin cartridge that contains both deionization resin and activated carbon after the UV-lamp instead of a pure deionization resin cartridge. 

The final TOC value, however, is completely dependent on your feed water. If your feed water has a high initial TOC value, you will need to pretreat it first, otherwise you may not be able to achieve the low TOC value you need. 

In addition, the higher value TOC that goes into the system, the faster you will exhaust the consumables, leading to shorter change intervals and higher total cost of ownership.

Online literature, papers and research forums are a good source of application information. 

However, for specific advice on filtration methods across a range of application workflows, Sartorius has an extensive range of test data, technical guides and application notes and are available to contact for advice and workflow queries. 

Further, product samples or demonstrations are often available free of charge to help users confirm the optimal lab filtration processes.
