Which instrument is used to measure grape must?

Grapes do not have "degrees" per se; what is measured is the sugar content in the must, which helps estimate probable alcohol content. We recommend two instruments:

• Handheld refractometer with 3 scales – Ref. 720.5150
  View product
  Measures °Brix, Baumé and probable alcohol. Requires only 2–3 drops.
• Mustimeter (glass hydrometer) with 2 scales – Ref. 414.
  View product
  Used with a 250 ml glass cylinder.
  Recommended cylinder

Both options are reliable, but the refractometer is more practical and faster.

Good morning:
In response to your enquiry, we need to know the Baumé scale of this chemical product. Once confirmed, we will be able to indicate the correct reference you should purchase together with the glass measuring cylinder, which is 524.017.

To use a hydrometer (aerometer for liquids) in a cylinder:

1. Prepare the materials:
   • Clean the glass cylinder and rinse it with a small amount of the liquid to be measured to avoid contamination.
   • Select a hydrometer suitable for the expected density; if it sinks too much, it is not the correct range.
2. Fill the cylinder:
   • Pour the liquid into the cylinder without overfilling it, avoiding overflow when inserting the hydrometer.
   • Ensure the product temperature is correct; otherwise, use equivalence tables.
3. Insert the hydrometer:
   • Hold it from the top and gently introduce it into the liquid.
   • Spin it slightly with your fingers so it does not stick to the cylinder walls and can float freely.
4. Allow stabilisation:
   • Let the hydrometer float freely and vertically without touching the bottom or the sides of the cylinder.
5. Take the reading:
   • Position your eyes at the liquid level and observe the graduated scale.
   • Read at the bottom of the meniscus (the curve formed by the liquid surface). This point on the scale corresponds to the relative density of the liquid.

Good morning,

Regarding your enquiry, please note that the oven model you mentioned does not have a cooling function; it only heats up to the programmed temperature.

The built-in fan is designed to homogenise the temperature inside the chamber during operation. Once the set time has finished, the fan stops and the temperature decreases naturally.

Please do not hesitate to contact us if you need any further clarification.

Kind regards,

Customer Service.

Thank you for your inquiry.

For the 250 ml Soxhlet extractor, it is necessary to use an extraction cartridge large enough to accommodate the sponge in its entirety without compromising the extraction process efficiency. Since the sponge has a radius of 10 cm (100 mm) and a height of at least 10 cm, here’s the information:

• The 33×100 mm extraction cartridges may be suitable for housing only part of the sponge, but they will not be enough to accommodate it completely due to the mentioned dimensions.
• The largest available cartridge, 41×123 mm, would also not accommodate the entire sponge, as its dimensions are still insufficient to house it fully.

Unfortunately, none of the available cartridges for this 250 ml Soxhlet extractor will be large enough to accommodate the entire sponge.

If you need further details or alternatives, please do not hesitate to contact us.

The Blue glass roll-on tube 10ml with stainless steel ball, reference 077.011-AZ, is made in China.

We hope this answers your question. Should you have any further enquiries or require additional information, please do not hesitate to contact us.

Thank you for visiting our website, and we look forward to hearing from you soon!

Hello, thank you for your inquiry.

The chemical thermometer with a range of 0 °C to 50 °C (reference 517.050-L) is an economical model, without certification, and with intervals of 1 °C. Due to its characteristics, we cannot guarantee a specific accuracy.
Currently, we do not have higher-quality or certified models for this temperature range.

We are at your disposal for any further inquiries or to help you explore other alternatives within our range.

Good morning,

Yes, clear glass vials can be sterilised after use and this procedure can be repeated several times. 

Some recommendations for the sterilisation process:

1. Pre-cleaning: Make sure that the vials are thoroughly cleaned before sterilisation to avoid residual contamination.
2. Inspection: Check the jars for damage, such as cracks or chips, which could compromise their integrity during sterilisation.
3. Sterilisation method: You can use autoclave, dry heat oven, or any other sterilisation method suitable for glass.
4. Proper handling: Use sterile gloves and sterile forceps to handle the bottles before and after sterilisation to avoid recontamination.

As for the exact procedure, it will depend on your facilities and available equipment. We do not intervene or offer specific guidelines in this regard.

Thank you for your interest in our products.
