Ground Glass Spirit Level Vials

Ground spirit level vials are generally used in applications which require a higher degree of accuracy than is achievable with the low cost plastic vials. We manufacture these in a wide range of sizes and sensitivities and produce many standard types as well as custom made products for OEM's. We have an advanced production facility which enables us to produce extremely high quality vials in small or large quantities at very competitive prices. Please contact us for more information.

Manufacturing and Quality Control

We have an advanced manufacturing and inspection facility which enables us to produce vials to the highest quality at very competitive prices. The production is split into several distinct processes. The first of these is the grinding which is key to the overall performance of the vial. We use custom designed grinding equipment to achieve a consistent and repeatable sensitivity to ensure that the movement of the bubble is smooth and linear over the operating range. The second process is to close the vials. This is done using automated equipment to ensure accuracy, and is continually monitored by our highly trained staff. Then the lines are printed onto the vial using high quality printing equipment and ceramic inks. The ink is then fired into the glass surface which makes the markings permanent and scratch proof. The final process is the filling, which is controlled by an automated vision system to ensure the size of the bubble is kept within tolerance. All of these processes take place in a clean environmentally controlled laboratory to eliminate the possibility of contact information. If you are interested in how these vials could work for your application, then please contact us for more information.1

These vials have a standard sensitivity of 35 arc minutes for 2mm. They are extremely high quality vials with a machined barrel form bore so they can be mounted or referenced against any of the four sides.  They have circle type inserts for line markings for optimum clarity and zero parallax error. They have a molded radius on one face only and have internally printed lines on the same face.
