The term leakproof applies under the following conditions: The VITgrip™ lab bottle is half-filled with distilled water and is closed with the supplied VITLAB® screw closure - after the ring of the tamper-evident closure clicks into place - with a torque of 5 Nm. Subsequently, the bottle is turned upside down and remains standing on the screw cap, for 15 minutes, without the filled-in water escaping. The test is carried out at room temperature (approx. 20° C) and atmospheric pressure.
