Glassware buying guide
Glassware is organised by function: reaction (round, flat-bottom and multi-neck flasks), separation (distillation heads, condensers, columns), vacuum (filter flasks, cold traps, high-vacuum valves) and handling (beakers, bottles, measuring cylinders, pipettes).
Nearly all items are borosilicate 3.3, which tolerates thermal shock and common solvents. Quartz is used where UV transparency or higher temperature is needed. Joints follow standard tapers — 14/23, 19/26, 24/40 and 29/32 are the common sizes — and adapters bridge mismatched joints or add a side arm, stopcock or hose connection.
For vacuum work use heavy-wall vessels, a cold trap between the pump and the system, and PTFE or high-vacuum grease on the joints. Sizes are listed as nominal capacity plus joint size; when a dimension is critical, send the drawing and we will confirm the geometry.
Frequently asked questions
Which joint sizes do you stock?
14/23, 19/26, 24/40 and 29/32 in most lines; other tapers on request.
Can I use these under vacuum?
Vessels rated for vacuum are marked heavy-wall and listed under Vacuum Pumps & Diffusion Systems or Filtration. Standard flasks should not be evacuated without a rating.
Do you make custom lengths and volumes?
Yes — most items can be produced to a specified length, volume or joint combination. Send a drawing and the joint sizes.
Are broken parts repairable?
Custom and broken items can be re-made to the original drawing; send a photo and the joint sizes for a quote.
