MANUFACTURER OF BESPOKE LABORATORY GLASSWARE & SCIENTIFIC GLASSWARE
Laboratory Glassware is a broad umbrella term we use to describe a wide assortment of scientific apparatus that is traditionally made from glass.
Glass is an exceptionally flexible substance to work with, and thanks to a number of unique properties it possesses, it is perfect for producing items of laboratory glassware.
As well as being durable, it is heat resistant, chemical resistant and can be sterilised easily. Perhaps its most basic property of transparency is the most important, as this means reactions are easier to observe.
Glass can be manipulated into all manner of shapes through glass blowing and can also be bent, cut and moulded. This flexibility makes it invaluable for a wide variety of applications, and it is in common use in chemistry, biology and analytical laboratories around the world.
Interchangeable Laboratory Glassware
The choice of interchangeable laboratory glassware products has diminished from the catalogues over the years making certain combinations of some of the larger cone and socket sizes no longer available. We still supply our customers who require these obsolete products from the whole range of interchangeable glassware.
As a specialist scientific glassware manufacturer, we are familiar with making these products so if you can’t find it in the catalogue we will make it for you. Adaptors, condensers, flasks, funnels etc, we can supply it. Single vacuum manifolds or Schlenk lines for laboratory use. Vacuum manifolds with a choice of socket or screw thread ends. Stopcocks -Single or double oblique – PTFE or glass all of the highest quality to avoid jamming of keys. Length and number of stopcocks to customers’ requirements.

Double wall reaction vessels for temperature control. Can be plain with water connectors or have a flat flange lid and a stopcock on the bottom in sizes from small up to 100mm flat flange, all made to customers’ requirements.
Condensers come in many forms and we can make anything from Leibig, Double surface or coil condensers. Also condensers for all water distillation units, some no longer in production.
Round bottom, flat bottom, Erlenmeyer or vacuum, they come in all shapes and sizes. We modify flasks up to 20 litre capacity, joining on single or multiple sockets, flanges or screw threads using only quality Schott flasks and components.
Sampling tubes or dip tubes are made in borosilicate glass for sampling products for analysis and can be up to 42 inches long for large chemical containers or shorter, such as 30 inches for sampling wine and spirits.
Replacement glass boilers, condensers and constant level devices for water distillation units. Complete distillation apparatus for many applications from essential oil apparatus to lavender oil extraction. Bespoke items made to customers’ requirements.
Laboratory Glassware Repair
Some types of laboratory glassware can be very expensive and a broken socket on a condenser or flat flange lid, or a jammed cone in a socket, or a broken stopcock on a funnel can usually be repaired. We will endeavour to repair products if it is economic to do so.
Selecting Laboratory Glassware
The type of laboratory glassware required will depend on the task that is to be performed. Many common products are mass-produced, easily available and low in cost. Some tasks, however, will require more complex and specialist pieces. In these situations, that item required maybe bespoke and require custom producing for the particular task.
When a new bespoke item of laboratory glassware is required an expert in the field of scientific glass blowing is needed. Glass Blowers can create complex and unique pieces designed specifically for a particular task.
A glass blower typically uses an open flame to heat the glass, which then allows for manipulation. Often the work is done by hand. However, some tools are used when creating specific products. Glass blowers are highly skilled, and it takes many years of training before an individual can create some of the more complex pieces.
Types of Glass Used
Laboratory Glassware can be produced from a number of different types of glass. Each variety has specific properties that make it suitable for different uses.
Borosilicate glass is the most commonly used type. It is naturally transparent and can withstand thermal shock. Borosilicate glass is used in a wide variety of applications including medical equipment, cookware and lab apparatus.
Quartz glass is capable of withstanding very high temperatures and appears transparent in certain parts of the electromagnetic spectrum. Also known as Fused Silica, it contains only silica, which means it is extremely heat resistant.
Fritted glass is a porous type through which gas or liquids can pass. It is often used in laboratories to filter items.
Silanized glassware has a coating that prevents organic material from adhering to the glass. It is often used in cell culturing.
Cleaning Laboratory Glassware
It will often be necessary to clean laboratory glassware. The best approach is to soak the glassware in a detergent-based solution. The solution will help remove any grease and also soften and loosen most contaminations. After soaking, the glassware can then be scrubbed to remove any particles that cannot be simply rinsed off. After soaking a triple rinsing process is typically used and the glassware is allowed to air dry on drying racks.
If you are using the glassware for an experiment which is very sensitive and where any contamination may affect the results, then soaking in a solvent or mild acid is recommended.
Common Types of Glassware
There is a wide array of glass lab equipment available. Below we highlight some of the most common pieces;
Test Tubes: Used to hold, mix and heat small volumes of chemicals.
Beakers: Basic glass cylinders used keep samples. Heavy-duty beakers are available to reduce breakages.
Funnels: Used for transferring powders or liquids from one vessel to another. Glass funnels are heat and chemical resistant and typically more durable than plastic funnels.
Petri Dishes: Used for cell culturing.
Laboratory Flasks: Available in many different types depending on there use. The common distinguishing feature is a wide bottom tapering into a thin neck.
Sampling Tubes: Long, thin glass tubes measuring up to 42 inches. They are used for taking samples of liquids.
Bottles: Used for storage of substances. Many glass laboratory bottles have specific features depending on their intended use. Amber coloured bottles are used for storing light-sensitive chemicals. Wide neck bottles aid with pouring. Specialists safety caps can be fitted if the bottles are to keep high-temperature substances. Square bottles help with reducing the space needed for storage.
Coil Condensers: Designed to cool or heat a substance, changing it from a gaseous state to a liquid state, or vice versa.
Microscopic Slides: Thin glass strips used for holding and viewing items through a microscope.
Bespoke Laboratory Glassware
Many items of laboratory glassware are becoming less and less common and the skills to produce them also slowly being lost.
Our team at Scientific Glass Services have 40 years experience in the field and can produce complex, custom made glassware to exacting specifications.
Our knowledge and experience also mean we can work with our customers to design items for specific tasks.
