Small pore size suits reduction of Mycoplasma in samples

The new Sterilin specialist filtration range enables life scientists to find a syringe filter or filtration unit with a pore size and membrane type to suit their most needs

The new Sterilin range of specialist filtration products is so extensive that life scientists are sure to be able to find a syringe filter or filtration unit with a pore size and membrane type to suit almost every application.

Choosing the correct pore size to suit a specific application is an important consideration when choosing a filter. Sterilin Syringe filters are available with pore sizes of 0.22μm and 0.45μm, and Sterilin Filtration Units in pore sizes of 0.10μm, 0.22μm and 0.45μm. The smallest pore size is ideal for the reduction of Mycoplasma in samples. 0.22μm filters are appropriate for applications such as sterilisation of media and aqueous solutions, filtration of buffers, protein binding and gas filtration/air monitoring. The largest pore size is suitable for the clarification of aqueous solutions and solvents, pre-filtration, filtration of protein-free media, solvents and aggressive chemicals, and for the sterilisation/ultra-cleaning of aqueous solutions.

Centrifuge tubes deliver high quality and increased speed capability

Sterilin has launched an extended range of sterile polypropylene centrifuge tubes

Sterilin has launched a new, extended range of sterile polypropylene centrifuge tubes that offers increased speed capability of up to 12,000 x g. The high quality standard range is suitable for a wide range of general laboratory applications and the premium range, which is certified free from DNase/RNase/human DNA and non-pyrogenic to 0.5EU/ml, is ideal for the demanding requirements of molecular biology and clinical laboratories.

The standard range of Sterilin Centrifuge Tubes is manufactured from high clarity polypropylene to ensure excellent transparency and chemical resistance. Available in 15ml or 50ml volumes, they have clearly printed graduations and a writing panel for ease of use. Both volumes are available with a conical base, which offers a high rcf value of 12,000 x g, but the 50ml standard tube is also available as a self standing, flat-bottomed tube, which offers an rcf value of 6,000 x g. They are supplied in cases of 500 tubes, containing re-sealable inner packs of 25 for convenient and secure storage of unused tubes. Alternatively, the conical based tubes can be supplied in recyclable cardboard racks, which offer excellent upright support and can be recycled with regular paper and cardboard waste.

All Sterilin centrifuge tubes offer leak-free performance and are gamma irradiated to ensure sterility; this partnered with certified assurance of RNase, DNase, human DNA free and of being non – pyrogenic, allows them to be used with confidence for even the most sensitive tests and experiments.

Improve 3D cell culture

New Iwaki Vecell 3-dimensional cell culture inserts, available from Sterilin, provide improved cultivation of adherent cell cultures and reliable cell growth. The inserts are designed for use with either 6 or 24 well culture plates.

In the past century, cell culture has become a widely used technique in research laboratories, starting with vaccine development in the early 1900s. The more advanced techniques used today give scientists a better understanding of cellular processes and, in particular, the effects of disease.
