BJP 10 Static Concentrator

The BJP concentrates urine through the absorption of water by absorbent pads located on the underside of an ultrafiltration membrane. Bence Jones protein will be retained on the membrane surface in the front compartment of the BJP unit because it has a 7.5 kDa MWCO membrane, a molecular weight cut-off far from the molecular weight of Bence Jones protein itself.

BJP concentrators offer a fast, gentle and convenient method to concentrate multiple clinical samples for analyses by electrophoresis and immunofixation. No pressure lines, vacuum pumps or centrifuges are required. The procedure is simple and straightforward. The operator loads the sample into the bench-top concentrator, waits for the sample to concentrate and recovers the protein concentrate with confidence.

A BJP 5 unit filled with 5 ml urine typically takes about 30-40 min for a 100 fold concentration with recoveries of at least 95-98 % BJP. The BJP 20 static concentrator performs a 100 fold concentration of 10 ml urine in 50 min. The hands-off operation allows the operator time to continue with other analyses in a busy laboratory environment while the device is left unattended to concentrate the urine samples. The impermeable dead stop pocket prevents the urine sample from concentrating to dryness.

BJP concentrators enable rapid and easy concentration of samples:

  • Up to 50% faster than the leading device
  • 20% less expensive than the leading device
  • Up to 98% recovery rate
  • Never over concentrates
  • Easy to fill
  • Easy to read
  • Easy sample removal
  • Choice of formats

Applications

  • Concentration of urine prior to electrophoresis for diagnosis of multiple myeloma and amyloidosis.
  • Concentrate spinal fluid prior to electrophoresis for diagnosis of meningitis and multiple sclerosis.
  • Increase titers of bacterial antibodies (H. influenzae, S. pneumoniae, Streptococcus) prior to latex agglutination.
  • Simple concentration of biological samples and dilute protein solutions.
