Closures
Whether protecting the sample from outside contamination or the workplace from the bottled toxic waste, closures guarantee tight and reliable seals. With a vast cap selection for best compatibility with any container, tailoring to specific contents is possible. Temperature resistant models allow any procedure to be completed safely. Available in different finishes, any sensitive chromatography sample is protected. The caps are easy to close with one hand and come in many colors to assist with identification.
