How To Sterilise Glass Bottles

how to sterilise glass bottles

Knowing how to sterilise glass bottles is important for anyone in the business of selling food and drink. As well as getting the glass clean of any dirt or residue that could be leftover from warehousing or transportation, the sterilisation process also kills off any nasty bacteria that would not usually be removed by just giving the glass a quick rinse in water.

Why Is Sterilising So Important?

You must sterilise your glass before use in consumer products for the following reasons:

  • Customer safety. If your glass is not sterilised properly, there could be some nasty germs lingering inside that could make your customers ill when they eat your product.
  • Product integrity. Some types of food or drink could react negatively with any bacteria that has been left on your glass packaging, therefore causing the taste or texture of your products to change.
  • Increases shelf life. By removing the germs and bacteria from your glass bottles and jars, you are increasing the amount of time that your product can be stored and safe to eat.

So how can you sterilise glass at home?

How To Sterilise Glass Bottles: Step By Step

This short guide is perfect for home bakers or small food producers to follow, however if you are a large producer, then it is more efficient for you to use large machines that are specifically designed to sterilise on a mass scale.

Step 1

First of all, you need to take your glass bottles and wash them throughly with hot, soapy water. DO NOT dry them with a tea towel.

Step 2

Next, you need to heat your oven to 140 degrees celsius or higher, place a sheet of baking paper on a middle shelf, then lay your glass bottles and *lids on it. Make sure that they are not touching each other, then leave to bake for 20 minutes until they are dry.

*Do not bake any lids that have rubber seals in the oven, as they will melt or lose shape. Instead, you will need to boil them in hot water and leave to dry in a rack.

Step 3

Take your glass out from the oven and leave to cool. Do not attempt to fill your bottles when they are still hot, as adding cold liquids to hot glass can cause the glass to crack. Once your bottles are cool, you are then free to fill with them with whatever wonderful drinks you so desire!

It’s that easy.

Specimen tubes and vials – 6 alternative uses


Glass specimen tubes and vials supplier UK

Glass specimen tubes and vials are mainly used in the chemistry, pharmaceutical, biology and biotechnology fields, for the collection and storage of organisms, chemical solutions and samples. These strong, reliable containers are manufactured from glass, which has good resistance to a range of chemicals and other liquids, powders, and capsules.


Our specimen tubes are made from type 3 soda glass, which is commonly used for foodstuffs and common chemicals. Our vials are manufactured from type 1 glass (borosilicate), which has high chemical and thermal shock resistance and is widely used for pharmaceuticals and chemicals, which are sensitive to changes in PH levels. Our tubes and vials also come with stoppers, snap-on caps or screw caps, to secure contents.


The good news is that specimen tubes and vials are not just limited to laboratories. If you have never worked in a laboratory and are never likely to, you could still make use of them for craft projects, displays and novelty products. Plus, our range of clear glass specimen tubes and vials all have a flat base, so they can be stood alone, in comparison with test tubes, which require a holding rack.


Here are our 6 alternative uses for specimen tubes and vials


Specimen tubes with flowersFlowers

Create a unique flower display by standing a few of our 30ml tall clip top glass vials in a row. You can use dried flowers or fresh flowers. Fill the vials with water (if using fresh flowers), cut the stems short and stand a single flower in each vial.


Herbs and spices

Spice up your kitchen with a quirky set of 20ml tall clip top vials to store herbs and spices in, such as saffron, cinnamon or cloves. You can fill them up from larger jars and they won’t take up much space on the kitchen worktop.


Specimen tubes with sweets inConfectionery 

If you want wedding favours that are a bit different from the usual sweet jars, our 25ml specimen tube with stopper would make an attractive confectionery container for guests to take home.


Bath salts

Our 30ml vial with screw cap would make a trendy bath salts container. If you use a few vials together as a set, you can put different scented salts in each vial.


Glitter and bead craft containers

Specimen tubes with sequins inCreate a craft kit by filling our 30ml vials (with fitted caps) full of glitter, sequins, small beads and other haberdashery items. If you’re into arts, you could also use the vials for inks, dyes and miniature paints too.

However, if you collect sand from each holiday you’ve been on and store and display it in our 15ml clip top glass vials, with a label stating where it originated from, it’ll make a nice display that will bring back memories of all the places you’ve visited.
