Cryopreservation is a process where biological materials such as cells, tissues or organs are frozen to preserve the materials for an extended period of time.
A moisture balance (also known as a moisture analyser) is an instrument that measures the moisture content of a sample. This is done by weighing the sample, then heating it to remove moisture and finally weighing the sample again. The final weight is subtracted from the starting weight and the difference in values is the moisture content. While easy to use, the setup and method development can...
Everyone has seen the standard blue screw caps that adorn every laboratory, but these are not the only option available.
DWK have a comprehensive range of caps for nearly every application:
Standard caps are blue:
The standard caps are blue and are made of food grade polypropylene and suitable for most applications. Made to standard GL bottle threads they are available in GL2...
Oxygen can dissolve into wine throughout production causing wine oxidation which in small amounts can be beneficial to some varieties such as red wines, but in large amounts can shorten the wine's life and lower the quality. Being able to measure the dissolved oxygen throughout wine production allows the winemaker to control and influence the amount of oxygen exposed to each variety before bott...
pH-Fix are Macherey-Nagel's range of non bleeding pH test strips which provide a number of clever and useful features. There are 15 varieties to choose from, covering different ranges between 0-14 and different sensitivities from 0.2 to 1.0 pH units. Other features include: Non-bleeding indicator dyes - no sample contamination Optimized colour scale - easy pH-measu...
The SD 400 Oxi L is Oxygen meter which allows the measurement of dissolved oxygen (DO) at a high level. This is done thanks to the optical technology of luminescence. It uses an Optical DO probe which has distinct advantages: Low maintenance Easy calibration Fast response High accuracy The applications for this meter include: Waste Water Water Treatment Marine Water Surf...
What is a Redox Potential? Oxidation Reduction Potential (ORP or REDOX Potential) measures an aqueous system's capacity to either release or accept electrons from chemical reactions. When a system tends to accept electrons it is an oxidizing system. When it tends to release electrons, it is a reducing system. When are Redox measurements required? There are a number of different reasons...
A. Yes there is, Duran Group offer the YOUTILITY bottle in four sizes all with a unique grip feature that can really benefit people with smaller hands who find conventional media bottles a bit difficult to get a good purchase on.
Features that make the Duran UTILITY bottle unique:
Specially shaped gripping zones on both sides of the bottle for easier and safer handling
With the new...
The TRUEscience team have had years of experience in supporting users of traditional pH meters. During this time they saw all the frustrations that people have when using these meters - unclear buttons, difficult interfaces, trouble saving and retrieving results. They wanted to create a new and unique way of measuring pH that makes the test quick and simple while still retaining a high level...
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...
The TRUEscience pH measurement system enables you to create user accounts for each person that will use the meter. If required, users can login before each measurement session so each action they perform in terms of calibration, pH measurements and logs will be tagged with the users name. Â This allows you to create an audit trail of what was done when and by who.
See the below video for insi...
Memmert's new climatic chamber, the HPP1400 is breaking new ground in its XXL format, its tailored to provide environmental simulation but on a large scale. The New Memmert climate chamber is the largest of its type on the market that does not require energy intensive cooling compressors or conventional heating. Â As with all appliances in the HPP series, the environmentally friendly Memmert Pel...
Thanks for sharing such a great information.. It really helpful to me.. I always search to read the quality content and finally i found this in you post. keep it up!
I came across your article about "DPD Tablets" on Camlab Info, and it's a valuable resource for anyone seeking information about water testing and analysis using DPD tablets. Your explanation of their usage and significance in water quality monitoring is quite informative.
This article on nanocolor tube tests is a gem for analytical enthusiasts. The idea of zero calibration is intriguing, and your detailed explanation makes it accessible. The step-by-step process helps demystify the technique for beginners like me. The use cases you've highlighted, particularly in...
Grant have introduced the new Controlled Rate Freeze Thaw (CRFT), which is a liquid nitrogen and cryogen free controlled rate freeze and thaw system for cryopreservation in a wide range of applications. Cryopreservation is a process where biological materials such as cells, tissues...
A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be...
Purchasing items using donated funds without the burden of VAT will now save many Millions of pounds each year which can be put to better use in advancing scientific knowledge to provide new treatments and cures that will shape the medicines of the future.
Working with pressure/vacuum conditions in the lab is common but not all products are designed to withstand this. Products with appropriate geometry and wall thickness are suitable for working safely with pressure. For example, filtering flasks, desiccators, or flat flange vessels, as well as...
