How long will a concentration take using a BJP concentrator?
A typical 50 fold concentration of 5 ml urine using the BJP 5 should take about 45-60 minutes. Using the BJP 20 a 50 fold concentration of 10 ml urine should take about 90-120 minutes. Speed of filtration is affected by several parameters including temperature, pH and protein concentration. Whilst BJP concentrators will provide rapid filtration in most environments, the following suggestions may be helpful in optimizing speed. Suspended particles will tend to foul the filter element and slow filtration speed. Pre-filtration with a syringe filter will clarify the sample and result in faster filtration speed and improved analytical results following concentration. An acid sample with a pH of less than 5 will take longer to concentrate than a neutral sample. Adjustment to neutral pH will result in faster filtration; however, this may alter slightly the concentration of the Bence-Jones Protein. Initial protein concentration levels will have a significant effect on concentration speed. Whil
