Firefly's basic cuvette for fluorometric applications. This cell is the same build as the Type 1 with the only difference being that all four sides and the base are polished.

Standard macro disposable cuvette box of 100.

Flow-through observation fluorometer cell with an open bottom and top.

FireflySci's fluorescent incarnation of the Type 11. This cell provides a transparent, airtight glass cap, which provides an airtight seal, ensured by the ground finish on the inside of the cap and the top of the cuvette.

The Type 21FL is the fluorescent version of the Type 21 standard PTFE-stoppered cuvette. That is useful for any fluorometer experiment that requires an airtight seal.

The FireflySci Type 41FL cuvette is our standard fluorescence screw cap cell and is a favorite among scientists who perform anaerobic work. The open SEPTA screw cap enables researchers to make sterile injections into the cuvette without compromising the experiment.

FireflySci's macro fluorometer flow through cell with detachable inlet/outlet quartz tubes. Enables a constant flow through the 2.8ml capacity observation chamber.

FireflySci's Type 58FL Macro Fluorometer Flow Through Cell with fused on vertical quartz tubes. Enables a constant flow through the observation chamber.

The Type 61FL fluorescence cuvette contains a graded seal quartz-to-pyrex adapter, which enables scientists and glassblowers to add on additional pyrex structures. The adapter is fire-fused to prevent leakage and ensure structural integrity. 

FireflySci's 65FL cryogenic fluorescence cell allows you to dip well into the low kelvins. This model contains a PTFE stopper, all polished surfaces and contains a fortified, extra-fused design to protect it against extremely low temperatures.

The Type 71FL fluorescence cell contains an inlet tube and a glass pouch chamber for catching excess gas produced by anaerobic experiments.

The FireflySci Type 501FL cuvette is a flow through cell with inlet and outlet tubes on the top and bottom of the cell. All surfaces are optically polished.
