Poor Man’s Buret
We’ve taken an ordinary syringe and converted it into
a buret. The stopcock controls the dispensing rate
from drop by drop to freeflow. Our Poor Man’s Buret can’t replace the accuracy of a glass buret, but you can’t beat the price. We even include the syringe plunger so that you can “unconvert” it and use the syringe.
Buret, Economy Choice
These very inexpensive burets have durable silk-screened graduations. The buret tip assembly comes with a length of tubing and a plastic stopcock. The buret tip assembly is provided with each buret. We stress that these are inexpensive alternatives.
