The BJP 5 benchtop static concentrator allows for the concentration of clinical samples up to 5 ml in volume and can be operated without a centrifuge for in vitro diagnostic (IVD) applications. Its dead-stop design provides maximum concentrate recovery where samples can be withdrawn without the need for glass Pasteur pipettes, making it ideal for concentrating urine and spinal fluid samples before gel and immunofixation electrophoresis for the diagnosis of multiple myeloma, light chain amyloidosis, and related disorders.
