By using the small (ca. 1/2 inch OD) vacuum tubing and a plastic syringe, you can pipette cleanly and with fairly accurate delivery volumes. Stretch one end of a one inch length of tubing over a 2 ml plastic syringe, and insert your pipettes into the other end of the hose. Much longer lived than standard pipette bulbs and less messy.
Use a quick connect on an air hose (the small end of the quick connect) to push solvents through microscale columns made from pipettes. It's much more convenient than pipette bulbs.
When combining column fractions, use "vacuum adapters" common for distillations . It's the piece that has a female joint on top, a mail joint on bottom and a side-arm. Equip the top with a rubber septum and teflon cannula to combine column fractions. Apply a vacuum using an aspirator and siphon your fractions into a flask.
Use a long needle attached to an air hose to dry your NMR tubes.
The 200 MW rule... anything under 200 molecular weight won't survive long on a high vacuum system.
Use a 16x100 test tube and 14/20 yellow "caplug" for small scale extractions. The "caplug" fits tightly enough that the tube can be inverted without spillage.
The empty automatic pipetter tip cases (for 200 microliter) make excellent stands for NMR tubes.
When using microliter syringes with metal complexes, such as Titanium Isopropoxide, rinse it immediately afterward withorganic solvent followed by acid, then clean as usual.
Never ever use a brush to clean out a high pressure reaction vessel or pressure tube. The brush can make tiny scratches on the inside and cause the glass to fail at high pressure.
