Interchangeable Laboratory Glassware – Quickfit® Understanding the Connections

How often have you spent time trying to find the right pieces of glassware to fit together to construct your set-up?

A Flexible Interchangeable Range

Quickfit® back in 1934 pioneered the idea of interchangeable laboratory glassware based on set joint sizes aimed to tackle this issue. Today this range comprises of over 1000 products, most of which feature their signature conical ground glass joints comprising of a tapered cone and socket which allows easy assembly of glassware from simple reflux to a complex fractionation apparatus.

Glassware Joints that Fit Together with Ease

This glassware is precision manufactured to ensures non-seizing joints.  A ground finish provides excellent vacuum performance and assured interchangeability.  Made from Pyrex® borosilicate glass it is highly resistant to chemical attack and can be used with most acids, alkalis and organic solvents along with usability over a wide temperature range.

The interchangeable conical joints are made to an accuracy that surpasses the requirements of ISO 383 & DIN 12242 regulations. A two-stage grinding process ensures that the joints have a precision 1:10 taper and super-fine surface finish, resulting in joints that have an exceptionally good seal with a greatly reduced risk of joint seizure. The excellent surface finish also ensures that the joint will not leak and will be gas and vacuum tight.

The Quickfit® sockets feature a rounded rim profile, this round design gives extra strength to the joint and is less prone to chipping than a square rim profile.

One key factor to understand with this range of glassware is the joint sizing.

Conical Joints
This is the most common type of Quickfit® joint and comprises a ground cone and socket. Sizes are described with two numbers e.g. 24/29.

  • 24 – Diameter of the wide end of the ground joint (in millimeters)
  • 29 – Length of the ground joint (in millimeters)

Joint sizes are available from 5/13 to 60/64. Most Quickfit® conical joints are manufactured to comply with European ‘B’ length joint dimensions, as defined in ISO 383.

Flat Flange Joints
This type of joint is utilised on large-capacity reactors and large diameter flasks, and also the construction of conduits for gases, vapours, and low vacuum extraction. The Quickfit® flat flange joints are available with bore sizes of 25 – 100mm. flat flange jiont
Other Joints including spherical and screw thread joints are also available in the Quickfit® range.
