Seward simplifies cell preparation

Enhances applications for Strainer bags to include sterile processing of tissue samples

Seward Limited, the UK manufacturer of the Stomacher paddle blenders and accessories used in sample preparation for microbiological analyses, has further enhanced the applications for its Strainer bags to include sterile processing of tissue samples for primary cell preparation.

Gamma irradiated sterile and available in a range of sizes, the Strainer bags are compatible with all laboratory paddle blenders, including Seward’s Stomacher 80 Biomaster series. Because they are fully containable and easily used in a sterile environment, the Strainer bags can be used for new applications in cell culture.

The 0.5mm pore size of the integrated strainer element within the Seward Strainer bag generates a uniformly homogenous cell suspension, says the Worthing-based company. This allows the cells’ passage through the pores of the central straining matrix and prevents contamination with undigested extracellular material, which can block pipettes. Produced to provide a sterile, secure environment for the preparation of single cell suspensions, the Strainer bag is suitable for the individual processing of a large number of samples.

“The new life-science applications of our robust Strainer bag technology represent the continuing, customer oriented, development to which Seward is committed,” said Stuart Ray, technical director at Seward Ltd.

“Cell scientists can simplify their primary culture preparations by straining the processed tissues to ensure trouble-free pipetting, whilst also increasing the viability of the cells produced as the end product.”
