Test Tube With Interchangeable Stopper
Product Code : EL-TT-10154
Lab Glassware Manufacturer supplies the Test Tube With Interchangeable Stopper from its manufacturing facility in Ambala, Haryana, to research and teaching laboratories across India and export buyers in Morocco, Algeria and Tunisia and other markets across the Maghreb.
Quick answer: This is a graduated glass test tube fitted with a standard interchangeable ground-joint stopper, available in seven height-by-outer-diameter sizes from 100×12mm up to 200×38mm. Because the joint follows a standard interchangeable size, a stopper from one tube can generally be used on another tube sharing the same joint size.

What "Interchangeable" Means for This Stopper
An interchangeable ground joint is manufactured to a standard size, rather than being individually paired and ground to fit only its original tube. That means a stopper from one tube in this range can generally be swapped onto another tube of the same joint size, which is useful when a lab needs to reconfigure setups, replace a lost or damaged stopper, or standardise stopper stock across multiple tubes rather than keeping a matched pair for every single tube. The graduated body adds the ability to read approximate volume directly from the tube, useful for quick reactions or dilutions where a separate measuring vessel is not needed. Seven sizes from a slim 100×12mm up to a larger 200×38mm cover a wide range of reaction and sample scales.
