With this Sartorius Density Determination Kit
you have acquired a high-quality accessory to your
electronic balance.
This accessory kit will ease your daily work load.
Please read the Installation and Operating Instructions
carefully before setting up your density determination
kit and working with it.
If your balance is equipped with a density
determination program, you can have the rho values
calculated by the program.
In this case, please follow the operating instructions
in “Getting Started.”
Perform density determination as described in the
density determination program.
Important Note:
The YDK 01-0D density determination kit can be
used for determining the density of liquid according
to weights and measures regulations.

Getting Started
YDK 01, YDK 01-0D
You can use the density determination kit, YDK 01or
YDK 01-0D, with the following balances:
– ME series balances (Genius series)
– BA balances with a readability ≤ 0.1mg
– BP/LA balances with a readability ≤ 0.1mg
– MC balances with a weighing range of 210 g
and up (Micro series)
– RC balances (Research series)
Preparing the Bar Frame
You must mount the adapter before the bar frame can
be placed on the balance.
Please use the adapter that is appropriate for the
balance you are using.
(approx. dimensions)
8 mm Ø, height 41.3 mm – ME balance
with gasket
7 mm Ø, height 16.5 mm – BA, BP*, MC and
RC balances
12 mm Ø, height 25.5 mm – BP**/LA balances
with a readability
≤ 0.1mg
** = BP 210 D, BP 300 S, BP 210 S, BP 160 P,
BP 110 S
** = BP 211 D, BP 301S, BP 221S, BP 161P,
BP 121S

Screw the appropriate adapter into the underside
of the bar frame base.
Now remove the following components from
the balance:
– weighing pan
– compensating ring for BA and BP balances
– pan support for BA and BP balances
Place the frame in the weighing chamber. The
wedge-shaped opening at the top of the frame must
face the direction from which the sample holder
(sieve/glass plummet) will be placed into the frame.
Always use the metal platform to hold a beaker.
Please position this platform through the frame so it
rests evenly on the base of the weighing chamber.
If you are using an BA, BP or ME balance, turn the
platform so it rests on the pins which are far apart. For
RC and MC balances, the platform should rest
on the pins which are closer together.
