History
The "Winchester quart" bottle first appeared in the UK in the 19th century with a capacity of 2 imperial quarts (2.273 litres).[3] At the time, a system of dry capacity measures known as "Winchester" was still in use. The Winchester bushel is still used in the US. However, the Winchester quart bottle has no relation whatsoever to any other units called "Winchester". In the 20th century, the Winchester Quart was metricated to two and a half litres.[4][5]
Construction
A "Boston round" has a cylindrical shape without a handle and a short curved shoulder. It is threaded for closing with a screw cap.
Common varieties used in the labs are as follows : e.g. Beakers, different
types of bottles as reagent bottles, screw capped bottles, Winchester quartz
bottles for storage of reagents, drop bottles, polythene bottles (wash bottles),
centrifuge tubes (round or conical bottom), flasks, measuring cylinders, test
tubes (different sizes and different capacities), pipettes (different volumes),
petri dishes etc.
