Test Tube Caps
Culture tube caps are essential pieces of laboratory equipment, as they ensure the safe handling of samples by sealing test tubes to prevent contamination. We have various caps available, including Kim Rak, Kim Kap, and NMR tube caps that are suitable for many uses and provide a tight and secure seal within the laboratory as well as dropper nozzles with pointed tips for fitment over the neck and dropper tip. Some stainless steel closures can provide storage for long periods.Depending on the sample access requirements, snap caps, and flange caps can provide a secure seal with minimal effort. Consider the tube, sample, and level of protection required to ensure the integrity of your results.
