1. Centrifuge design has remained unchanged for many years. There is only so much that can be done to a spinning rotor placed in a box. There is a wide range of machines available covering every imaginable tube size and maximum spin speed.
2. Chromatography equipment is constantly being updated and refined. New techniques and improvements in software and use are constantly being made. The key is to determine exactly what you require and then find a system that does it.
3. Dialysis is rarely used in IVD manufacture, and there has been little development over the past few decades.
4. Electrophoresis equipment is now mainly modular and based around precast gels. Documentation and data management systems are improving, along with detection sensitivity.
5. Filters are now available in almost any material, size, pore size, and color. Basic filters are widely available and do not differ significantly in performance. Filters with specialized characteristics are available from a more limited number of suppliers, and may be more challenging to locate.
6. Membranes, test strips, wicks are not freely interchangeable between manufacturers. Each manufacturer has a range of niche products that cannot be replaced; however, equivalents can be found for most materials.
