Platinum Wire, Fused with Test Tube is a laboratory apparatus commonly used in microbiology and chemical laboratories for handling and transferring small quantities of substances or microbial cultures. The platinum wire is permanently fused into a glass test tube or glass handle, providing a strong, stable, and heatresistant support for safe laboratory use.Platinum is highly resistant to heat and chemical corrosion, allowing the wire to be easily sterilized by heating in a flame without damage. The fused glass handle ensures safe handling, insulation from heat, and convenient operation during lab. procedures.
