Fluicell introduce BioPen®FLEX, a product exclusively developed for experiments using upright microscopes. This product almost doubles the addressable market for the BioPen range. BioPen FLEX features a longer microfluidic tip and a thinner holder than previous models, thus giving better access to cell samples with limited working distance. Researchers can now carry out studies on individual cells and tissues with the high resolution using another type of commonly used microscope setups. The BioPen FLEX system has all the benefits of the established BioPen series. The classic BioPen tip and holder, optimized for inverted microscopes, will now be marketed as BioPen® PRIME. The BioPen FLEX and BioPen PRIME systems are interchangeable component platforms, specially designed to meet the requirements for drug testing and cell biology with single cells or thin tissues.
