We have been working side by side with customers for nearly 25 years fabricating custom glassware to suit their needs. Whether it is a completely custom item or a custom modification to an existing catalog item we are happy to accommodate you. Just provide us with a blueprint or even a simple hand drawing will do and we are happy to help.

Class A Volumetric Glassware, Made to Order

As a dedicated volumetric glassware manufacturer, North Jersey Custom Glass produces flasks that meet the precise tolerance standards labs depend on for accurate measurement. We stock and fabricate Class A laboratory glassware across a wide range of sizes, so whether you need a single flask or a full set for a teaching lab, we can supply it to the same exacting calibration standard. Because of the sheer number of sizes we offer, we don’t list every option online — a quick call gets you the exact specification you need.

Custom Sizes from 15ml to Over a Gallon

We can manufacture volumetric flasks from 15ml up to over a gallon, and if a size is not already in stock, we get it right into production. This makes us a practical source for a custom volumetric flask outside standard catalog ranges, as well as everyday laboratory volumetric glassware used across teaching labs, quality control departments, and research facilities. Every flask leaves our shop calibrated and inspected before it ships.

As a long-standing volumetric flask manufacturer with nearly 25 years in scientific glassblowing, we back every Class A volumetric flask with the same craftsmanship and attention to detail that has earned our shop repeat business across New Jersey and beyond.

Accurate volumetric work depends on more than the glass itself, so we pay close attention to neck design and graduation placement to make readings easy and repeatable at the bench. Many of our clients order sets of matching flasks for a single procedure, and we can batch-produce these together so calibration and finish stay consistent from piece to piece. If your lab is being audited or preparing for accreditation, we’re also glad to provide documentation on the glass and manufacturing process behind your order.
