Seward enhances Strainer bags application range

Seward, a UK based manufacturer of patented Stomacher Paddle Blender range, has further enhanced the application range of 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 fully compatible with all laboratory paddle blenders, including Seward’s Stomacher 80 Biomaster range.

Seward said the 0.5 mm pore size of the integrated, robust strainer element within the Seward Strainer bag generates a uniformly homogenous cell suspension.

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 ideal for the individual processing of a large number of samples.

Seward technical director Stuart Ray said 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.
