Description
Rimless round bottom test tubes are engineered for high-temperature laboratory applications such as flame exposure, autoclaving, and dry heat sterilization. The rimless design reduces the risk of contamination and breakage during handling or sealing.
Perfect for use in organic chemistry, thermal testing, plant science experiments, and thin-layer chromatography (TLC), these tubes are compatible with flame-sealing techniques and support secure plugging with stoppers or cotton.
Constructed from LabChoice BORO 3.3 borosilicate glass, they offer superior resistance to thermal shock, chemical corrosion, and repeated sterilization cycles. Supplied by LabChoice Australia, these tubes are trusted for precise, high-integrity performance in both teaching and research laboratories.
