What glassware accessories do I need to set up a distillation or reflux apparatus?

At minimum a lab stand, one or more clamps sized to your joint diameter, and Keck clips to secure ground-glass joints against separation. A lab jack is standard for raising and lowering a heating mantle or bath under the flask without disturbing the rest of the setup.

Why is capacity a filter rather than its own category?

Capacity is a property of a product, not a type of product. Modelling it as a filterable attribute lets you narrow every vessel type by volume at once, and keeps a 500 mL beaker and a 500 mL Erlenmeyer in their correct product categories rather than lumped into a shared size bucket.

Are Keck clips reusable and autoclavable?

Standard polypropylene Keck clips are reusable but have a lower temperature ceiling than the glassware they secure, and repeated autoclaving degrades them over time. Check the clip’s stated temperature rating against your cycle before autoclaving them alongside the glass.

Glassware & Accessories

Borosilicate glassware and the hardware that supports it — flasks, beakers, and cylinders alongside the stands, clamps, and connectors that hold a setup together.

View cart →

Glassware and the hardware around it are usually bought together but catalogued apart, which is why they share a department here. A round-bottom flask is only as useful as the clamp, stand, and Keck clip holding it at the right height over a mantle.

The Glassware branch splits by vessel type — beakers, Erlenmeyer flasks, filter flasks, round-bottom flasks, separatory funnels, volumetric flasks, and the graduated cylinders used for volume measurement. Capacity is recorded as a product attribute rather than a separate category, so you can filter for 500 mL across every vessel type at once instead of hunting through a size-specific subcategory.

Stands & Clamps covers the support hardware: lab stands and jacks, clamps and flange clamps, GL connectors, cork stands, and Keck clips for securing ground-glass joints.
