Wash port

Washing port connector tubes (2/cartndge). Attach 20-cm tubing to barb hose end of dialysate hose connector. Fit male adapter MTLI 250 to free end, and protect with R94 plug. 

Remove the protector from the right-hand access port. Take out a washing port connector tubing from its bag (ensure that the male adapter is protected with the R94 plug). Fix it to the access port with the spring loading connector (see Fig. 2 and Note 15). 

Remove the washing port connector tubing from the right-hand SP38. 

In the sample port the sample is introduced into the test module and the reaction takes place. The fibrous matrix is a glass fibre which is coated with antibody. The conjugate well is prefilled with enzyme conjugate. The substrate well is prefilled with a substrate solution that is used as both substrate and wash solution. The wash port serves to dispense the substrate. 

Figure 5b illustrates the schematic of a 2-input microfluidic AND gate. The AND gate in Fig. 5b incorporates a waste reservoir (WR) and nine indexed electrodes. Electrode 1 and electrode 2 are the two input ports XI and X2 electrode 7 is the output port (Z). Electrode 9 is the washing port (WD). 

When the cake space was nearly full, the delivery pressure of the slurry would start to rise (or the filtrate rate to faU), giving the signal to stop filtration. If the cake was to be washed, then wash liquor could be introduced from the same channel as the feed (simple washing), and could then be discharged with the filtrate or separately. Alternatively, special wash ports may have been used, to give flow across the thickness of the cake (through washing). 

Some attempts have been made to reslurry the filter cake without having to open the filter press. However, a number of problems appear, eg, bending of the plates due to uneven cake deposition or cavitation, uneven dewatering and washing within the frames, and plugging of the inlet ports. 

A fraction of airborne salt always passes through the filter. The method recommended for determining whether or not the foulants have a substantial salt base is to soap wash the turbine and collect the water from all drainage ports available. Dissolved salts in the water can then be analyzed. 

When a clear fdtrate is required right from the start it is good practice to form a thin heel that serves as a fdter medium over the exposed cloth. This is done by either a "cloudy port outlet" that is recirculated or, if solids are settling fast, by allocating a portion of the table after the cloth drying dam and prior to entering the vacuum zone to act as a "sedimentation pool". When intensive cake washing is required.

A further novel reduced-resin design is the ISEP from Advanced Separation Technologies, Inc. This employs a carousel holding 30 fixed bed columns of resin that continuously rotate to match 20 fixed top and bottom ports. This design also provides for high purity water and reduced regenerant demand and wash volumes, but at a significant capital cost. 

Figure 10.1 shows a basic online SPE LC/MS/MS system, a column switching system (Kahlich et al. 2006) that includes a six-port switching valve, an injection valve, an SPE cartridge, an analytical column, SPE washing and HPLC pumps, and MS detector. The online process has three steps ... 

The feed is introduced at the top of the annular column at the 0° position. The feed solution is followed by a wash buffer, which is introduced to the annular column through the main inlet port. A 1 vol.% mixture of 2-propanol in a 100 mmol/1 ammonium acetate buffer was used as wash buffer. In the washing zone the nicked DNA followed by the RNA are eluted from the column according to their affinity to the resin. At 180° offset from the feed nozzle the elution buffer (5 vol.%) 2-propanol in 100 mmol/1 ammonium acetate) was pumped to the annulus of the column. The elution buffer was used to strip off the bounded Plasmid DNA. Regeneration of the column was achieved by a 20 vol.% mixture of 2-propanol in 100 mmol/1 ammonium acetate buffer. All of the above-mentioned steps, i. e., feed, wash, elution, and regeneration, were done simultaneously and continuously on the P-CAC system.
