Techne Culture Vessel User Manual

Description

A permanent magnet is sealed into the flexibly mounted stirrer. The
position of the stirrer bulb is controlled by another magnet in the
MCS platform mounted on a pulley wheel. As the pulley wheel turns
the magnet orbits under the culture vessel causing the stirrer bulb to
trace a gentle path around the trough in the bottom of the vessel.

The design causes the culture to be carried gently upwards in the
centre of the vessel to the surface, then it is dispersed outwards
where it loses energy and drops slowly to the trough.

The electronic speed control ensures the stirring speed is consistent
and repeatable at all settings.

The soft start facility causes the stirrer to increase (or decrease)
speed gradually over a period of 20 seconds until the set speed is
reached (or stirring stops).

The interval mode allows stirring to be programmed for “on” periods
from 6 seconds to 5 minutes and “off” periods from 2 minutes to 2
hours.

Standard culture vessels are calibrated in volume and have two
necks and a central filling port. There is also a 5 litre vessel which
has five necks and a central filling port. All culture vessel parts are
suitable for repeated autoclaving at 121°C and 15psi for 30 minutes.
All internal components are biologically inert.

Both the culture vessel and the stirring rod are siliconised before
they leave the factory.

The MCS platforms are designed for incubator environments with a
maximum temperature of 40°C and 95% relative humidity, non
condensing.

Sterilisation of Glassware

In the interests of public health and the safety of our employees we
cannot accept any returned glassware without our previous
authorisation.

We require a certificate of sterilisation from the user before giving
such authorisation.

A suitable form of certificate is enclosed with the glassware when it
is despatched from Techne.
