Ideal for use with beakers, Erlenmeyer flasks, test tubes, boiling (Florence) flasks, and burettes, these retort clamps include a high-strength alloy boss head to secure the clamp to a frame or other apparatus. The clamps, constructed of solid die-cast zinc with a blue powder coating, have a metal adjustment screw that allows for precise pressure when gripping glass objects to avoid potential breakage. Each clamp is non-ferrous, rust-free, and long-lasting in any laboratory application and contains a swivel between the clamp and the boss head. The boss head will accept a rod up to 18mm in diameter, and, if needed, the boss head and clamp can be separated with a 5/32 Allen wrench. The vinyl-coated clamps (23458, 23460, 23461) are excellent for higher temperature applications, while it is not recommended that the cork-lined clamps (23459, 23466, 23467) be placed in direct heat.
