Glass Labware Accessories

Laboratory glassware accessories are used to support, connect, close, and handle laboratory glassware during experiments and routine procedures. Common examples include watch glasses for sample handling, stoppers for compatible glassware openings, and retort stands for supporting laboratory apparatus.

LabSafetyShop offers laboratory watch glasses, glassware stoppers, heavy-duty retort stand bases, and stainless steel support rods. These products support laboratory glassware assembly, sample preparation, titration, and general laboratory equipment setup.

A laboratory watch glass is a shallow, concave glass dish commonly used for holding small samples, evaporating small amounts of liquid under suitable conditions, and covering compatible beakers. Its suitability for heating depends on the glass material and manufacturer specifications.

A retort stand provides a supporting framework for laboratory apparatus. It typically consists of a base and vertical rod to which compatible clamps, rings, and holders can be attached. Retort stands are commonly used to support burettes, flasks, funnels, and other equipment during laboratory procedures.

Select a laboratory glassware stopper based on the glassware opening, joint size or standard, stopper material, chemical compatibility, and intended operating conditions. A correctly matched stopper helps provide a suitable closure, but pressure or vacuum use requires specifically rated equipment.

Choose a retort stand base and support rod based on the weight and dimensions of the apparatus, required rod height, base stability, and compatibility with clamps or holders. Ensure the assembled equipment is properly secured and suitable for the intended laboratory procedure.
