Objective
New pieces of tubing and connectors to work with. Need to re-create set up so that we are using the new pieces.
Lab Protocol
Materials
- syringe connector: female lure thread style to 200 series bard, 1/16" (1.6 mm) ID tubing
- tube connectors: t-connectors 1/16" ID
- tube connectors for PVA/gulteraldehye mixing: y-connector 1/16" ID
- tubing for everything: tygon IN 1/16"
- Image below shows this new set-up that was constructed. Tubing lengths were kept the same as well as rates from previous entry.
Data
- PVA pumping too slow, could be cause of clog previously. Have that syringe on grey pump moving 0.1 ml/min.
- Put gluteraldehyde into ethylacetate pump to save on space and make pumping easier, but PVA is backing up towards syringe.
- Looking at other rates: RCS Adv. 2014, 4, 46536; used 0.1 mL/min discontinuous (for us PVA) and 200 mL/hour continuous (for us ethylacetate).
- Moved ethylacetate into 60 mL syringe and changed rate to 5 mL/min and PVA to 0.1 mL/min
- Added coloring to PVA to locate beads in tubing more easily.
- PVA too viscous so diluted it by doubling volume with 10% HCl.
- Change flow rate again to 0.09 mL/min for PVA and 3 mL/min for ethylacetate.
Notes
- Final change to flow rate seemed to work best.
