What is a Bostwick Consistometer?

The Bostwick Consistometer is a simple, dependable instrument which determines the consistency of various materials by measuring the distance which a sample flows under its own weight.  The Bostwick Consistometer is used extensively in the food industry for measuring the consistency, flow rate and viscosity of jams, jellies and other highly viscous products such as tomato paste, tomato ketchup,...

How can i measure the sugar content in food stuffs?

In today's busy laboratory manufacturers look towards sample measurement automation to speedup analysis in a bid to improve workflow. This makes the whole production more efficient and maximises profits. Normally refractometers are used in a single use mode and reading times are typically less than one minute, but in some circumstances automation can give rise to higher productivity by reduc...

Bostwick Consistometer – To Incline or Not

The Bostwick Consistometer is used all over the World to check the quality of sauces and condiments. In our in-house training session we do blind product tests and clearly define the differences between brand of ketchup and mustard. This is a testament to the value placed on Bostwick Consistometer tests by the top food manufacturers. We continually get questions about set-up of the consistom...

How To Fix An Abused Bostwick Consistometer

The value of a Bostwick Consistometer is that it’s easy to use, which makes it simple to do repeatable testing. The Consistometer is made of stainless steel. One would think that this means a long and useful life. However, as I regularly discover, the real world often defies theory. A Consistometer’s value is diminished if its leveling plate and screws get bent out of alignment. The story th...

Measuring food consistency

We often get asked about measurements in food and a key measurement is the consistency of sauces, jams and other foodstuffs such as yoghurt's and creams. The simplest way to measure this is with a bostwick consistometer. An example of how to use this for tomato sauce is demonstrated in this video from a Food company in the US. The bostwick consistometer is available from Camlab and ca...

Viscosity of Liquids- Table of liquids and mpas values

Viscosity describes the flow behaviour of liquids. It is defined as the internal frictional resistance of a liquid to the application of a pressure or a shearing stress. The dynamic viscosity is normally given in millipascal-seconds (mpas) and is usually determined by using a  viscometer. For further information on the viscosity of liquids: http://www.buerkle.de/media/files/Downloads/Visc...

What's the difference between a Hydrometer and a Brineometer?

A hydrometer is an instrument that is made of glass and consists of a cylindrical stem and a bulb weighted with mercury or lead to make it float upright. It is used to measure the Specific Gravity (SG) of liquids. In other words the ratio of density of the liquid to the density of water.The SG of water is 1.000 at 4°C. For example the lower the density of a substance the farther the h...

The time is right with a Techne Gelation Timer

[caption id="attachment_2257" align="alignleft" width="130" caption="Techne Gelation timer"][/caption] A Techne digital Gelation Timer provides accurate, reproducible results for manufacturers testing how long a sample or product needs to set from a liquid into a solid gel during polymerisation. Designed to discriminate between the viscosity of a liquid and the elasticity of a gel, the Te...
