ERWEKA MultiCheck 5.1
The ERWEKA MultiCheck 5.1 is a universal
testing device for fully automatic measurement
of sample weight, thickness, diameter/length
and hardness.
The advanced design of the unit, beginning
even from the outside, shows the innovative
functions such as switchable hardness testing
principle (“Constant-Speed” and “Constant-
Force”), fully automatic speed adjustment of
tablet singulation and transport, independent of
sample size and surface, advanced high-
accuracy thickness measuring system and
state-of-the-art alignment tool for irregular
shaped oblongs and coated tablets.
The new MultiCheck 5.1. comes with a system
for separation of the samples via an oscillating
funnel. This system eliminates the need of vi-
brator strength adjustment as previously neces-
sary for the other MultiCheck versions.
In standard configuration the MultiCheck 5.1
offers an integrated Sartorius weighing cell
(accuracy +/- 0.1 mg). On request the new unit
is also available with Sartorius CPA 64 (with
integrated display) or CPA 64 OCE (gaugeable
version with integrated display, accuracy +/-
0.01 mg).
Further the MultiCheck 5.1 can be fitted with an
overworked alignment flap, a tool which allows
aligning and holding oblongs in the correct posi-
tion for and while breaking. At the version 5.1
the alignment flap (down-holder) is modernized
in such a way that now it creates more force to
hold the samples while the breaking process.
The MultiCheck 5.1 in combination with the
ERWEKA TabSelect flap/switch and the Venturi
air transport system can be connected to any
single or double sided tablet press.
Function:
The samples are individualised automatically by
a new system for separation of the samples via
an oscillating funnel and then deposited onto
the weight measurement boat. From there the
samples are transported to the test stations by
a linear feeder which allows alignment of ob-
longs as well as odd shaped samples such as
sugar coatings. In case of problematic samples
a down holder in the hardness test station is
available as an option. A patented step in the
transport way allows you to switch tablets which
tend to lie on the side.
The unit is controlled by an optional external
PC.
Software Package MC.net (included):
ERWEKA MC.net software is directly connected
via Ethernet network connection with the Multi-
Check 5.1. The Software allows PC operated
external control of the Hardness-/Combination
Tester as well as online storage of user man-
agement, product data, results as well as CFR
21/11 compliant Audit Trail.
Due to the high memory capacity of a PC the
capacity of stored users, product data, results
as well as CFR 21/11 Audit Trail is nearly
unlimited.
Tolerances for test-results can be individually
set or automatically set according to USP or
Pharm.Eur.
An optional alarm-function creates stop of the
unit and alarm in case a sample is out of the set
pass/fail tolerance. In this case the user may
check why the measured result is out of the
pass/fail limit.
The CFR 21/11 compliant user management
allows individual definition of user groups, indi-
vidual user rights for each group including addi-
tional rights for individual users etc.
Similar to users the MC.net software allows to
switch product data inactive and, on request,
only to display active product data. The MC.net
software is a tool to create various statistical
reports from the test-results, such as test-run
statistics, graphical batch statistics, trend
analysis etc.
The integrated CFR 21/11 compliant Audit Trail
tool of the MC.net software automatically stores
all Audit Trail data of the connected unit.
The Audit Trail data may be sorted according to
date or user/user group, displayed and printed
for hardcopy documentation.
