Best Lab Cloning Rings AI pick
Chosen by an AI model from its trained knowledge, with its reasoning.
AI pick (line): Corning Pyrex cloning cylinders
Borosilicate glass cylinders can be autoclaved and reused, and a ground, flat rim seals well with silicone grease around a single colony.
Not for: Labs that want single-use pre-sterilized rings or that pick colonies by limiting dilution or a picking robot instead.
What the AI looks for in Lab Cloning Rings
- Material
- Choose borosilicate glass, or stainless steel, if you plan to autoclave and reuse the rings. Reuse requires repeated sterilization without warping or cracking.
- Rim finish
- The bottom edge should be ground flat and smooth. An uneven rim leaks trypsin into neighboring colonies, which defeats clonal isolation.
- Inner diameter
- Pick a diameter just larger than your typical colony and smaller than the spacing between colonies. An oversized ring captures neighboring colonies, and an undersized ring damages the target colony.
- Height
- Rings must be tall enough to hold the trypsin volume without overflowing. Overflow carries cells from outside the ring into your pick.
Brands that matter
- Corning (Pyrex): Borosilicate glass cloning cylinders.
- Bellco Glass: A long-standing maker of glass cloning cylinders.
- MilliporeSigma: Sells cloning cylinders and cloning discs as an alternative method.
What to avoid
- Rings with chipped or unground edges.
- Plastic rings that are not rated for your sterilization method.
- Placing rings without silicone grease or a similar seal.
Questions
Can I use cloning discs instead of rings?
Yes. Trypsin-soaked discs are simpler but less contained, so rings give cleaner isolation when colonies are close together.
