Product Description
Purify small amounts of solid efficiently by crystallizing and separating in a single vessel. Craig tubes remove the losses that come with filtering milligram quantities, giving students and researchers better yields and cleaner products from microscale recrystallizations. They are a staple of microscale organic teaching programs.
This listing is for Kimble catalog number 747332-0001: KONTES Craig Tube, 1mL. These tubes are made from borosilicate glass 3.3 and come in 1 mL and 2 mL sizes. Tubes and plugs are sold separately, so you can choose a glass or PTFE plug. Because separation is done in a centrifuge, two tubes are needed to balance each run, so plan purchases in pairs. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
Key Features
- Single-vessel recrystallization – Crystallize and separate without transfers.
- Two capacities – 1 mL and 2 mL tubes.
- Borosilicate glass 3.3 – Withstands heating during dissolution.
- Plugs sold separately – Choose glass or PTFE plugs.
