Frequently Asked Questions

AI
Measure the widest part of your flask or the base of your burette. Ensure the inner diameter (I.D.) of the ring is slightly larger than the glassware to allow for easy placement while remaining snug enough for stability.
Stainless steel generally offers superior long-term corrosion resistance, especially in environments with acidic vapours. Chrome-plated steel is a cost-effective alternative that works well for general education and low-impact use.
It varies by product. Some are sold as individual rings, while others are bundled in sets with boss heads or full retort stands. Always check the product description to see if the clamping hardware is included.
