Practical beaker protection: These stainless steel beaker covers are sized to fit a range of laboratory beakers, from 1.2 L up to 12 L. Placing a cover over a beaker is a simple but valuable step in careful laboratory practice: it helps limit evaporation of the contents during heating, mixing, and standing, and it reduces the chance that airborne dust, particulates, or debris will settle into and contaminate a sample. That protection matters both for preserving sample integrity and for keeping measured volumes and concentrations stable over the course of a procedure.
Durable stainless steel construction: Each cover is made of stainless steel, a material chosen throughout laboratories for its corrosion resistance, easy cleaning, and tolerance of a wide range of chemicals and temperatures. Unlike disposable films or foils, a stainless cover can be washed and returned to service many times without tearing or degrading, which makes it both economical over its lifetime and dependable in demanding, high-throughput environments where covers are used and cleaned constantly.
A full range of sizes: The group spans six sizes so a cover can be matched closely to the beaker in use: 1.2 L, 2 Qt, 4 L, 6 Qt, 8.25 Qt, and 12 L. A well-matched cover sits properly and delivers the best evaporation control and contamination protection, whereas an ill-fitting cover leaves gaps. The 12 L version is supplied in a case of four, which suits laboratories that standardize on larger vessels and want covers on hand for each.
Everyday reliability: Because they are metal rather than single-use, these covers hold up to routine autoclaving-style washing cycles and repeated handling far better than disposable coverings. Reaching for a correctly sized stainless cover becomes a habit that quietly protects samples during heating on a hot plate, while a preparation stands between steps, or during short-term storage on the bench, supporting cleaner, more repeatable results across the laboratory's daily work.

FAQs
What are these beaker covers used for?
They are placed over laboratory beakers to help reduce evaporation of the contents and to limit airborne dust and debris from contaminating a sample during heating, mixing, or storage. Made of stainless steel, they are reusable and sized to match a range of common beaker capacities from 1.2 L to 12 L.
What material are the covers made from?
Each cover is made of stainless steel, a corrosion-resistant metal valued in laboratories for durability and easy cleaning. Stainless steel withstands routine washing and many chemicals better than disposable coverings, so the covers can be reused across many procedures in laboratory and industrial settings.
What sizes are available?
The group includes six sizes: 1.2 L, 2 Qt, 4 L, 6 Qt, 8.25 Qt, and 12 L. Matching the cover to the beaker in use gives the best fit for evaporation control and contamination protection. The 12 L cover is supplied as a case of four.
Do the covers fit all beakers?
The covers are offered in six sizes to suit a range of beakers, so choose the size closest to your beaker's capacity for the best fit. Because beaker diameters can vary by manufacturer, confirm the cover size against your specific beaker before ordering if an exact fit is critical.
Are the covers reusable?
Yes. Because they are made of stainless steel rather than a disposable material, the covers can be cleaned and reused across many procedures. Stainless steel holds up to routine laboratory washing and resists corrosion, which supports a long service life in typical laboratory and industrial use.
