AMPI Auto-sampler: Automatic sample feeder or sample changer and sampler for liquids

The Animal Monitoring Platform is proud to announce the launch of the affordable automatic sample feeder and sampler robot for liquids such as milk, water, blood or urine or any other acqueous samples. The first model of the auto-sampler which will be launched is the basic “AMPI 2b”. The high-end version “AMPI H5” will add various, customisable features.

What is it, what does it do?

Each AMPI automatic sample feeder is in its test most basic version an automatic sample changer. wholesale mlb jerseys Such automatic sample changer allows to test a tray or rack of  around 100 sample vials (sample cups, pots, tubes) sequentially. Such rack or tray of samples is a two dimensional plane where the cheap nba jerseys sample vials (sample tubes, cups, pots) are positioned. The sample probe (also called sample needle or sample sucking tube) of the automatic sample changer will move from sample to sample (i.e. sequentially) each time a signal (instruction) is received from an external source (or automatically, after a given time delay, optional).

How many samples (maximum)?

The exact amount of samples which can be tested in one tray or rack, depends on the size of the sample vials (also called sample cups or sample pots). A rack or tray of 216x216mm (prelim. specs, can change without prior notification, please contact us) can be placed on the device. As a concrete example, these dimensions lead to around 10 by 10 sample vials (100 sample vials in total) in case the vials have an 18mm diameter and 2mm spacing on the rack  (tray) between the vials (cups, pots).

Of course we can also make larger size upon request. Please contact us via the online form so we understand your exact need.

Sample probe with or without pump?

The automatic sample feeder operates via an aluminium or the plastic sample probe (also called sample needle or sample sucking tube) which moves from sample to sample. Optionally a peristaltic pump for sucking the liquid from each sample vial (or sample cup or pot) can be included. Such optional peristaltic pump also enables automatic rinsing of the tubes and probe besides enabling stirring and homogenising of the liquids before actual Started measurement starts (sample preparation).

Sampler versus sample changer / sample feeder.

Finally, with peristaltic pump and in the optional reverse mode, the device can also operate as a true sampler by injecting an exact dose of liquid into each sample vial (sample cup).

Which signals or instructions are needed?

Via a signal (a string in your preferred format) on a communication port of the automatic sample feeder (USB, RS232, Wifi, Bluetooth, CANbus) , the sample probe (also called sample needle or sample sucking tube) of the sample feeder will move to the center of the next sample position in order to access the acqueous liquid (milk, blood, urine, other) in that sample vial.

The default instructions (strings) which are needed over RS232 will be specified in the coming months. Please contact us in the meantime; we usually customise according to your needs.

Who customises, who programs?

The sample vials are positioned on a two dimensional plane (basically a rack or tray of samples). In our factory, we program the sample vial positions depending on your sample cup (sample vial, pot) size. Common sample vial sizes are for instance 32mm as upper diameter. The next sample position will therefore be fixed at about 36mm from the previous sample position. The advantage of us performing the customisations is that we can fully test the system and we are used to customise.

Characteristics of “AMPI 2b”:

In December 2016, we will launch the most basic model, “AMPI 2b” with the following preliminary characteristics:

Pricing starts from €2470 EXW per sample feeder unit for water, urine, milk or blood (aqueous liquids) testing and goes up to €4390 Mastitis: EXW (excluding upfront costs for customisation and for on-demand certification)
Low maximum operating speed, max. 3000 samples/day
Operation at room temperature
No certificates besides TUV or SGS for electronics, no FDA approvals (on request)
USB or RS232 communication for instructions from and to your instrument, sensor, equipment or computer
Dimensions approx. 450x450x300mm, around 15kg total
110VAC or 240VAC, confirm during ordering
Sample vials (cups) positions with cups or vial size from 10 to 80mm can be pre-programmed in our factory with according rack or tray, for a minimum ordering volume (MOQ, nr of devices ordered).
Vertical movement of sucking tube can be pre-programmed in our factory from 10 to 50mm
Integrated liquid (milk, blood, urine, water) level gauge to detect empty or insufficient samples
Automated recalibration menu option for two dimensional positioning system
2 rinsing positions

These preliminary specifications can change at any time without prior notice. The prelim. drawing shown is only an illustration, not final. Final specifications will be confirmed on a best effort basis once you place your order.


Optional features, future model AMPI H5:

On future models, bij such as the high-end model “AMPI H5” cheap nfl jerseys we can include extra features. Please indicate on the online quote request form which optional features are important to you:

When livestock is raised in the pasture-based system they are let to graze freely and eat nutritious green grass and other plants that are easily digested by their bodies. The livestock welfare is greatly increased when they graze on pasture.

Sustainable livestock farming also helps in minimizing damage to the environment plus the produces such as beef, eggs and milk is much more nutritious and taste better than food from factory farms.

Livestock Health Benefits:

Livestock that are raised in limited factory farms have less quality life than those raised on pasture. Livestock when raised on pasture can move around and live a natural life where else in factory farms the animals are all crowded in confined facilities. These facilities do not have sun light or fresh air allowing bacteria to develope and affect the animals. This then causes the animals being provided with antibiotics which is not best for the livestock.

Since a great deal of livestock eat grass, grazing them on pasture has a lot of benefits. Some of the benefits will be the animals are able to produce saliva which is great for neutralizing acids that is in their digestive tract. Since grain fed livestock produce less saliva they frequently suffer from dehydration, intestine harm and even death.

Human Health Benefits:

Livestock raised on pasture produce more nutritious eggs, meat, milk which is ideal for consumers then livestock raised on grains. Adding to that, pasture raised foods have a much healthier balance of omega-3 and omega-6 fats then your conventional foods. Their supplement levels are greater as well.

It’s no question that sustainable livestock farming is the way to go if you want to be a successful livestock farmer. The livestock are reared in a healthy way and the produce is healthy for us humans.
