Globe 111167 Square Cuvette Plug Caps
These polyethylene plug caps fit standard square spectrophotometer cuvettes and are supplied in a bulk quantity of 1000 pieces for laboratory use. The caps provide a secure closure that helps prevent sample spillage and evaporation during measurements. They are intended for technicians and researchers who need a reliable, single-use sealing option for routine spectrophotometry.
Packed as 500 caps per bag in two bags
The two-bag configuration keeps half the supply sealed until needed, reducing the risk of contamination and making it easier to manage inventory in busy labs. Each bag can be stored separately or distributed to different workstations without opening the full 1000-count package. This packaging suits facilities that process large batches of samples and want to maintain clean handling practices.
Polyethylene material limits chemical compatibility
The caps are moulded from polyethylene, which resists many common aqueous solutions but may swell or degrade with strong organic solvents and certain concentrated acids. Users must verify compatibility with their specific reagents before relying on the seal for critical assays. The press-fit design also means the seal depends on cuvette tolerances, so a leak test is advisable for volatile or hazardous samples.

Questions about this item
How often will the polyethylene plug caps need replacement during regular spectrophotometer use?
Each cap is designed for single-use applications; the 1000-pack provides 1000 individual replacements for square cuvettes.
What limits how many samples can be processed continuously with these caps?
The practical limit is the 1000-cap supply; each cap seals one square cuvette per measurement cycle.
Do the caps generate heat or require power during extended daily operation?
No, the passive polyethylene caps add no heat, noise or power draw to the spectrophotometer workflow.
