 Heater & stirring rods
|
|
|
|

|
Immersion heater rods
These rods are especially suitable for avoiding defervescence in boiling or distillation in a beaker or Erlenmeyer flask.
Made of high-quality soda glass, reusable and simply ideal for many applications. |
|
|
Stirring rods
For mixing and homogenizing mixtures of chemicals and samples. Ideal for stirring even hot or boiling substances.
Made of high-quality soda glass. Reusable and suitable for many applications. Also available in borosilicate glass or quartz glass. |

Twisted glass tubes
|
|
|
|
|
|
|
|
|
By heating up and twisting them, we can produce twisted glass tubes and capillaries. These tubes then have a larger surface
inside in relation to their length and can be used as cooling units, for instance. They can also be used as ornaments and
decoration articles. |

|
Rated break points
|
|
|
|
|
|
|
|
|
As a special feature we can equip capillaries and tubes with rated break points. For this purpose the tube or
capillary is notched at the desired point. If shearing force is exerted on the tube then,
the tube will break at the predetermined point. In order to avoid unintended breakage,
it is recommended to use tubes and capillaries with middle or strong walls. |

Cloning Cylinders
|
|
|
|
|
|
|
|
|
Cloning cylinders are particularly suitable for cloning single cells or cell groups separately on a culture medium.
Simply by putting the cloning cylinder on the respective cell or cell group, these are separated from
the rest of the cells on the culture medium.
Cloning cylinders are made of high-quality borosilicate glass and so, heat sterilization is no problem.
The plane bottom of the cylinders allows an exact positioning. |

Connecting branches
|
|
|
|
|
|
|
|
|
These short formed components are fused on measuring electrodes and are used for the filling and emptying of the electrodes.
With their bulge they are also particularly suitable as connecting piece for hoses. They are mainly produced in lead glass,
borosilicate glass and soda glass. |

Glass fibre connector
|
|
|
|
|
|
|
|
|
In order to connect optical wave guides with each other, special capillaries with a specific geometry is necessary.
These connectors are produced of a capillary tube with a very exact inside diameter in order to position both fibre
ends exactly in front of each other.
In order to thread the glass fibres with more ease into the connectors, these need to have a taper on both sides
which is significantly larger than the typical inside diameter of about 150 μm.
Additionally, the edges are fire-polished to avoid a possible cracking off of glass dust and grains,
which could soil the inner channel. Already during the production we are taking care to keep the inner channels free from any dirt. |
In addition to that, we can rinse all parts separately with ethyl alcohol to remove possible soiling.
We can also produce special glass fibre connectors for you with particular inside and outside measurements for your specific needs.
Small batches from 500 items on are possible. |

Hollow glass balls
|
|
|
|
|
|
|
|
|
Form
These hollow glass balls are blown into a mould. Melting them down, a small spigot at the end of the balls comes into being.
On the one hand, this spigot makes them float nicely, and on the other it can be equipped with a fixing clip,
so that the balls can be arranged on a rod. The walls of the balls are very thin, nevertheless they will withstand
an external pressure of up to 6 bar (0.6 MPa).
Measurements
These balls have a diameter of approximately 32 mm and a wall thickness of 0.35 mm. The upper part of
the balls is flattened out a bit. |
Material
Soda glass is a transparent, inexpensive glass that fulfils usual technical requirements. However,
it is not suitable for application in aggressive media and is not resistant to thermal shocks.
Characteristics
Hollow glass balls are mainly used as floats. Due to their light weight and great volume
they are simply ideal for this kind of application. Additionally, with the small spigot at
the bottom of the ball a mounting of the ball is possible. |
|
|
Fields of application
|
| Hollow glass balls are ideal for a wide range of applications. |

Thin glass slices
|
|
|
|
|
|
|
|
|
Due to our optimized cutting process we are in a position to produce extremely short sections from rods and tubes which can,
among others, be used for covering sensors and sensible components. Alternative manufacturing methods require much more work,
like e.g. drilling circular cut-outs into small slices later. However, there is one disadvantage: the surface of the slices
that have been produced by cutting them off a tube or rod are finely matt. This structure can be corrected by fire-polishing
the surface later, but this polish, however, cannot fulfil optical standards. |
|
Further options during the production
|
With a groove in the rod or tube, cut in before the single sections are cut off, special gaps in the slices can be created through which wires or other elements can be lead.
For the production of the slices, there are different glass qualities available in form of tubes, like e.g. soda glass (lime-sodium carbonate glass), borosilicate glass 3.3, Kovar sealing glass, lead glass or quartz glass and some other materials. Even materials similar to glass, like ceramics, ca be processed this way. |
