ULTRASONIC CLEANER, LABORETTE 17, SIZE 1
For gentle cleaning of analytical and micro-precision sieves and other sensitive components, with no risk of damage. And for dispersing suspensions for particle size analysis.
Typical fields of application:
- for gentle cleaning with no risk of damage to sensitive components, such as micro-precision sieves and glass.
- in chemical reactions, e. g. when extracting vegetable substances, for accelerating and improving the results of the process.
- for dispersing suspensions for particle size analysis.
Method of operation:
The ceramic oscillator generates high-energy vibrations at the base of the bath and thus a cavitation effect throughout the bath liquid.
Features of performance:
- simple handling
- effective cleaning of analytical sieves
- compact design - bath and generator in a single housing
- safety tested in accordance with TÜV (CE mark)
- 2 year guarantee

VIBRATORY FEEDER, LABORETTE 24, WITH WIDE CHANNEL
For slow, metered feeding for uniform, broad material feed of flow able materials for a wide range of applications.
Typical fields of application:
- slow, metered feeding of flow able materials for e. g. for sample dividers, mills, mixers, balances.
Method of operation:
Vibration of a channel of high-grade stainless steel conveys flow able material from a funnel to the open end of the channel in a uniform stream.
The rate of flow can be controlled by a separate control unit which alters the vibration amplitude of the channel.
The control of vibrational amplitude is achieved by a microprocessor controlled unit which ensures that even the smallest quantities of material are uniformly conveyed.
Features of performance:
- channel and funnel of polished high-grade stainless steel
- Microprocessor-controlled electronics
- Easy to clean - funnel can be pushed aside
- Choice of V-shaped feeder channel for narrow, directed sample feed, U-shaped feeder channel for uniform, broad material bed
- Maintenance-free components
- Separate control unit
- Safety tested in accordance with TÜV (CE mark) and 2 year guarantee
Equipment:
The Vibratory Feeder is delivered with wide U-shaped channel and funnel, but without stand, which can be ordered as accessories, if required.
The wide U-shaped channel can be easily replaced by a V-shaped channel for narrow, directed material feed.
| Voltage / Electrical Details: |

ROTARY CONE SAMPLE DIVIDER, LABORETTE 27
For representative sample dividing of solids and suspensions with a dividing accuracy of 99.9 %.
Typical fields of application:
Rotary Cone Sample Divider form a symbiosis with extremely accurate analytical instrumentation. They are used in research, development and quality control laboratories to provide small but representative sample quantities for accurate analysis.
Method of operation:
Accurate sample division is now achieved by a combination of three principles of division within a single unit: The sample is passed via a hopper onto a rotating dividing cone whose profile simulates the process of coning and quartering. The sample material passes over the surface of the rotating cone and is accelerated outwards by the centrifugal force of the entire system. From there it is fed into up to 30 separate channels. The individual samples are collected in glass sample bottles.
Because of the rotation and the number of channels of the dividing head, the number of divisions reaches up to 3000 dividing steps per minute, so the feed to each channel is made up of a very large number of separate samples - a distinguishing mark for good sample division.
Features of performance:
- a basic machine can be used with a choice of 6 dividing heads
- up to 3.000 divisions per minute
- representative sample division accurate samples up to 99.9 %.
- safe for use with foodstuffs - processes dry free flowing samples or suspensions without additional modification
- choice of division ratios
- quick fit clamping of the sample bottles 250 ml and 500 ml as standard feature
- different sized collecting vessels in glass from 15 ml to 500 ml
- safety tested (CE mark) and 2 year guarantee
Equipment:
The Rotary Cone Sample Divider is delivered without dividing head. Dividing heads are available with different division ratios and materials. The appropriated dividing head must be ordered separately.

115 V/1~ |
| Frequency: |
50-60 Hz |
| max. particle size: |
depending on the used dividing head 2.5 mm, 10 mm |
