PP Mix Cups - Volumetric capacities from 6ml -2000ml

​

PP Mix Cups come in a variety of sizes and are manufactured from a selected high quality Polypropylene. They whole range has several distinguishing features, the most obvious if the rounded radius at the bottom of each container. 

​

There is no 'Mixing Dead Zone' when using a PP Mix Cup. The rounded radius is a vital characteristic to the internal sides and base of the PP Mix Cup containers. This smooth curved profile at the corner compliments the constant, entire rotational movement that the DAC technology creates so that mixing occurs, inside the sealed container without need of a blade. 

​

Any 90° angle (squared edge) of a container side wall and base, will not compliment the rotational material flow inside the mixing container. Although material may look mixed, the flow of product can be reduced here compromising the 100% mixed objective that using the Hauschild SpeedMixer has. Remember all DAC Hauschild SpeedMixer instruments® have always induced this material mixing ability since the advent of their technology since 1973.

​

Dependent on viscosity and filled content of a particular material, a 'Mixing Dead Zone' may not be detected unless particle size analysis is conducted using a microscope, Hegman gauge or TIDAS Instrument.

​

The PP Mix Cups will achieve best thermal resistance that Polypropylene as their inherant properties insulate due to exemplary quality control used when sourcing the raw product and in process control during and after the moulding process.

​

The generous side wall cross section offers stability, strength and retained  integrity at high, low and ambient temperatures. The 360° securely mating thread in all PP Mix Cups and Lids prevent escape of mixed or unmixed material enhancing a heath and safety standard your company can rely upon.   

​

PP Mix Cup Lid

​

Each PP Mix Cup has a mated thread in its corresponding PP Mix Cup Lid. The integral course helix thread is designed to be easy to open and close, whilst providing a tight reliable seal. To enhance surface area in closure, two types of inner lid seal are available.

​

PP Mix Cup - Inner Lid Seal

​

The inner Lid Seals fit inside the actual threaded Mix Cup Lid. This standard 'wadded' inner lid seal is a precut disc that can be easily inserted by hand into the internal recess of the threaded lid. Once inserted these should stay firmly in place and will not fall out. They can be bonded in with a hot melt adhesive if required. 

​

​

PP Mix Cup - PP Safety Seal 

​

The PP Mix Cup Safety Seal is an additional Safety Seal which is totally optional. This Safety Seal sits on the top shoulder of an open PP Mix Cup before the lid is screwed on. They function with or without the 'Inner Lid Seal'. They also offer a welcomed secondary barrier in laboratories where strict rules for powder handling or active ingredients apply, such as medical / pharmaceutical environments. They can also benefit the handling / processing of materials that have a strong odour.

Using a PP Mix Cup

​

All Hauschild SpeedMixer instruments have upper and lower weight ranges that they will successfully operate within. We calculate this by: -

​

Mixing weight (load) = Total weight of (Cup + Holder + Materials)

​

The load is critical to the SpeedMixer functioning correctly. Because of this many different PP Mix Cup Holders are available for the same container. In a lot of cases a light and heavy version will offer flexibility to use more or less material so that strict weight tolerances can be observed correctly.

​

​

PP Mix Cup Volume vs Weight - S.G

​

To relay an important fact here, imagine your own chosen coffee mug. If we had two of them, and filled one to the top with small gold coins and the other with feathers. You will agree that they would both be different weights. 

​

This is because the weight to volume ratio of feathers to gold are very different. The measurement used to quantify this is Specific Gravity, or 'S.G' for short.

​

Every liquid product has a different S.G. Water (H2O) has an S.G of ~1.0. Therefore 1 litre of water weighs ~1000gms / 1kg. 1 litre of small gold coins would weigh more than 16kg. 1 litre of feathers would weigh next to nothing in grammes.

​

The S.G of gold is ~17, so seventeen times heavier than water. Feathers, well we don't need to go into it but they'd weigh less than 100gms.

​

Our example simply determines the difference of product weights to volumes. 

​

Each PP Mix Cup has a published volume. You can see these on our spec sheet. When selecting your PP Mix Cup / Holder your selection needs to take into account: -

​

Minimum and Maximum weight your chosen SpeedMixer can accommodate.

Diameter and height of the PP Mix Cup thinking will it fit.

Which product do you add first, second third etc. This we call the method of addition.

How will your chosen ingredients behave during mixing.

What speed and time will I need to set on the SpeedMixer.

​

Lots to think about - If you need our assistance and guidance when making your calculations, we are happy to help and assist when necessary. This is actually covered in our basic operator training, delivered to machine operators when commissioning new machines but we are here at all times to help you get it right. We are always more than happy to advise you on this. 

​

​

Processing multiple PP Mix Cups at once.

​

You are not bound to processing just one single sample every time the SpeedMixer is started.

​

Multiple quantities of certain containers can be housed in our specialist holders, some accepting up to eight containers. These allow simultaneous mixing as one single batch. When mixing more than one container at a time, the speed of processing will be a huge increase to productivity.

​

​

Bespoke Mix Cup Holders

​

Custom made, bespoke holders are available for most other types of mixing vessels such as syringes, cartridges and laboratory vials. You are not tied to using just Hauschild PP Mix Cups in your chosen SpeedMixer if you have a reason or need to use others.
