Hi George - Thanks so much for your feedback. As a supplier of rapid chemical tests for in-process control in food and beverage industries, we are not familiar with commercial procedures for making fruit juices. You may seek support from local sources such as government agencies related to agriculture and food processing. There may be industry associations related to food processing or beverage production that may offer support, training, or networking opportunities. Quality control procedures are essential for ensuring the safety, consistency, and quality of fruit juices. The specific quality control measures may vary based on the scale of production, regulatory requirements, and the type of fruit juices being processed. We offer various rapid tests for in-process control including MQuant® Ascorbic Acid Test that is used to determine levels of natural ascorbic acid (vitamin C) in foods such as fruit and vegetable juices, and also to check how much ascorbic acid has been added to certain foods as a preservative or antioxidant. Hope this helps!

@@MerckLifeScience Thank you for your response!

The Reflectoquant Hydroxymethylfurfural (HMF) test, item 117952, is suitable for use in juices, fruit juice concentrates, and jams. For optimal results in your particular application, we suggest following the test instructions provided with the test kit. We also suggest verifying the HMF content by employing a reference method to validate the test results. In the event of discrepancies between the results and those of your reference method, we recommend consulting the application note and decolorizing the sample using polyvinylpolypyrrolidone.

Hello, @abdelrahmanelshadid310. To ensure we meet all your needs, we kindly recommend reaching out to our customer support team via our website: ms.spr.ly/6055YkrrV. Please make sure the correct country is selected in the top right corner.

@sokolaliji4012 We've developed a specific app note for determining the HMF content in honey using the Reflectoquant Hydroxymethylfurfural (HMF) test: ms.spr.ly/6054Ynhvw (please make sure the correct country is selected in the top right corner.) Please note that while we haven't verified the method for use with other honey products, we'd recommend the same approach for honey powder. We highly recommend measuring the HMF content using a reference method to validate item 117952 Reflectoquant Hydroxymethylfurfural (HMF) test for the specific application of honey powder.

The Reflectoquant Hydroxymethylfurfural (HMF) Test has a measuring range of 1.0-60.0 mg/L of hydroxymethylfurfural (HMF).

@@MerckLifeScience y la lectura del blanco no es necesaria, por que en su protocolo dice que se mida con un tira blanca, pero en el video no lo hicieron, para luego hacer un calculo de conversión de mg/ml a mg/kg?

Determining the blank value of honey depends on its color. For repetitive measurements of the same type of honey it's sufficient to determine the blank value once. In general, it's advisable to take the blank value into consideration even when light-colored types of honey are being investigated for the first time. With regard to the conversion from mg/ml to mg/kg, please note that the calculation is required because the honey is dissolved in water. However, usually you give a statement of HMF content in mg/kg, so the protocol provides the required calculation scheme from mg/ml to mg/kg. Hope this helps! Please let us know if you have further questions.

Thanks for your question! It's important for beverage manufacturers to comply with the local food additive regulations to ensure their products are safe for consumption and meet quality standards. If you're a beverage manufacturer, or considering commercial production of drinks containing ascorbic acid, it is advisable to consult the specific regulations and guidelines applicable in your country or region. The Reflectoquant Ascorbic acid test strips presented in the video are suitable for quickly measuring levels of natural ascorbic acid in food and beverages. Please let us know if you have any other questions!

Hi @mdimranhossain9495, thanks for sharing your interest in the Pall hydrophilic filter integrity testing procedure, specifically for the Flurodyne filter media. We appreciate your feedback and will keep this topic in mind for future discussions. Stay tuned for updates!

Thank you, glad that you enjoyed this video!

Thanks for your comment! To prepare 0.1M Tris-HCl, remember, 0.1M is the same as 0.1 mol/L. We are making 0.5L and will need the molecular weight (MW) for Tris-HCl: 157.594 g/mol. Let’s calculate: 0.1 mol/L x 0.5L = 0.05 mol. Next, multiply by MW: 0.05 mol x 157.594 g/mol = 7.88 g Tris-HCl Please let us know if you have any other questions! Happy to help.

Thank you for your question! Yes, it can be autoclaved or sterile filtered if desired, depending on your application and standard lab practices. After autoclaving, remember to let it cool and check the pH to ensure it hasn't changed.

Hi María - Thanks for your comment! A zero adjustment must be performed for each cell type. The zero adjustment for concentration methods is stored within the spectrophotometer separately for each cell type. The period of validity of the zero adjustment for concentration methods can be edited in the system settings. When a zero adjustment has already been performed for the inserted cell type and the selected method, the date of the most recent zero adjustment is displayed in the info line. If you have more questions or need more info, please contact our Tech Service (ensure the correct country is selected in the top right corner): ms.spr.ly/605594YBZ

It's too runny to be like silly putty, but this is actually how to make silly putty at home. You just have to use a lot less liquid starch.

@@scootermom1791 no it's still slime and less starch just creates rubber that's dried and hard within 2 hours. It's also not moldable no matter any consistency. This is slime.

@@tambram4677 it was called silly putty before there was anything such as "slime," which is just a watered down version of Silly putty.

@@scootermom1791 no slime is not a water downed version of silly putty. Silly putty is a polymer putty and slime is...well your video. Not even close to the same thing.

Hi Samiran, thanks for your interest in joining the team. You can find all available positions and apply online at www.merckgroup.com/en/careers.html. Best of luck with your application.

It would be silly putty if they had added less liquid starch.

Hi Rodrigo, Thank you for your feedback. We're glad you like it.

Hi Kristal, thanks for reaching out. For more viscous streams you need to use higher pressure to force the fluid through the membrane, for very viscous fluids (PVA), we have had to go over 200psi just to get material to pass.

Hi Amber, thanks for reaching out. It is an automated integrity test systems, you can learn more about this system here: ms.spr.ly/60549BDLY
