50ml MetalFree® Centrifuge Tubes with Flat Caps, 25 per Rack, Sterile

Labcon’s MetalFree® centrifuge tubes are made with ultra-clean resins for the tube and cap and processed to ensure that common trace metals are kept below an ICP-MS detection level of one part per billion (1 ppb). They can be used for storage and analysis tasks that require extremely low levels of the most common metals. These tubes are produced with a proprietary process that virtually eliminates common metals. Far cleaner than metal-free tubes, offering a simple 1 part per million (1 ppm) certification, these tubes are unique. Developed in Labcon’s own lab and using an inductively coupled plasma mass spectroscopy (ICP) system, these tubes are free of more than 20 common trace metals to a detection level of 1 part per billion.

Metals Tested: Calcium, Magnesium, Zinc, Vanadium, Cobalt, Lithium, Cadmium, Iron, Manganese, Copper, Sodium, Chromium, Lead, Mercury, Aluminum, Silicon, Nickel, Phosphorus, Potassium, Selenium, and Arsenic

Labcon’s MetalFree® centrifuge tubes are not only free of ultra-low levels of trace metals. These tubes are also lot tested and certified free of detectable nuclease, endotoxin, and ATP contamination. MetalFree® centrifuge tubes are available in 15ml and 50ml sizes in Labcon’s patented fibre racks or loose bags. Labcon’s MetalFree® tubes are also available in a snap-cap 1.5ml microcentrifuge tube. All Labcon’s sterile products use medical-grade packaging and are radiation sterilised following a validated ISO 11137 method to a sterility assurance level of 10-6. Racked tubes are packaged in recyclable fibre racks.
