Hold tubes on a consistent slant using Thermo Scientific™ Nalgene™ test tube slant racks. Useful for hardening media or incubating liquid cultures at a consistent 5° or 20° slant. These racks are keyed with numbers and letters for easy identification and are stackable when empty.

• After microwaving, set tubes filled with media at either 5° or 20° slant
• Media will harden with a consistent slant
• Higher specific gravity than water so stays submerged in a water bath; won't float
• Autoclavable (note: autoclaving will reduce strength over time)
