NTL-Student Experiment Kits SEK
The whole student experiment kits for physics from NTL: simple - fast - safe...
Our Studentexperimentboxes SEK are the ideal solution for student experiments in secondary school physics lessons. With their topic-orientated structure and division into physical sub-areas, they cover all disciplines of physics lessons - from mechanics to modern physics.
Our student experiment system has been developed over many years of experience and in close co-operation with teachers. The compositions are closely harmonised with the curricula and education plans of the federal states.
The numerous advantages of our student experiment kits at a glance:
Topic-orientated structure and division according to physical sub-areas
All areas of physics (mechanics, thermodynamics, electricity, optics, radioactivity, modern physics) are covered.
Organising the sub-areas didactically and thematically into several boxes
The equipment and parts for a specific topic area of a physical sub-area are sensibly grouped together in a box. This allows students to carry out experiments on the chosen topic using as little material as possible. This ensures efficient use of materials and space at the workplace.
Clarity of the box contents
Almost all student experiment boxes only contain one layer of material, that means we do not have any confusing intermediate shelves that have to be removed from the boxes and further restrict the already small working area.
Robust material for student experiments and availability
The material we use is specially designed for student experiments and is characterised by its robustness and durability. Unfortunately, damage, defects and signs of wear and tear cannot be ruled out, especially over long periods of use, which is why individual parts are available at all times and for the long term and can be easily replaced. In addition, each part in the student box can also be ordered separately and purchased individually if required.
Extremely sturdy storage boxes
Our storage boxes are extremely stable and can be stacked on top of each other without slipping. All boxes have a removable and lockable lid that can be positioned under the box during the experiment so that it fits perfectly and is also non-slip. We are the first and only manufacturer of teaching materials to use only 100% recycled plastic as the base material for our boxes.
Moulded box inserts
Each of our boxes contains a device-moulded box insert in which all parts are clearly arranged. The box inserts are made of plastic, so they do not become brittle and therefore have a long service life.
The standard scope of delivery of our SEKs includes (storage in sets):
Complete equipment set for a group of students
This means that students have everything they need for their experiments right at their workstation. Spontaneous additional experiments on the respective subject area are possible at any time - ideal for school classes with a wide range of levels.
Storage box incl. lockable lid
All parts are stored safely and, above all, protected from dust everywhere. The latches ensure that the lid stays securely in place at all times.
Individually moulded plastic box insert
Each item has its own desginated place. This makes it easier to put them away and check that everything is complete - good for the students and also for the teachers.
Well-organised box storage plan in the lid
This ensures that everyone knows immediately where each item is located in the box. The box storage plan also makes it easier to buy missing parts - because all parts are listed with name and article number.
Our student experiment boxes are usually offered as a set, i.e. each working group receives the appropriate box for carrying out the chosen experiments, which contains all the materials for the respective subject area.
NTL student experiment boxes SEK in set storage:

Set storage
all parts required for an experiment are stored in a box
- ⇒ entire equipment for each group
individual, device-moulded inserts
- ⇒ needed items quickly at hand
coloured box storage plans on the iunside of the lid
- ⇒ make it easier to put items away again
- ⇒ easy check for completeness
Our extremely solid boxes are a central and important element in set-by-set storage:

Our NTL boxes are...
- ... exceptionally stable.
- ... very good non-slip stackable.
- ... equipped with a removable lid.
- ... available in 3 sizes.
- ... made of 100% recycled materials.
- ... stackable on a trolley and therefore highly mobile.
The box inserts are made of plastic
- ⇒ do not becomoe brittle
- ⇒ long service life
Your and our contribution to greater sustainability
With our NTL storage boxes, we are also making a small contribution to greater sustainability in the physics collection. Since summer 2021, we have been the first manufacturer of teaching materials in Germany to produce the storage boxes for our equipment sets for student experiments from 100% recycled plastic!
This will also make your physics teaching materials collection a little more sustainable:
Rethink – Recycle – Reuse.
However, you can also choose to store your student experiments in blocks. In this case, all similar parts are stored in a drawer in the cupboard and the pupils only take out the parts they need for the planned experiment.
NTL student experiments in block storage:

Block storage
All similar items are in one tray
- ⇒ only required items for each group
- ⇒ optimum utilisation of space in the cupboard
Unsere NTL-trays...
- ... are stable thanks to a reinforced base.
- ... have deep moulded handles at the front and back.
- ... have grooves for optimal spacing of partitions.
- ... are available especially for NTL modules PIB.
Important for the stundents - and also for you: safety!

Important for student experiments in thermodynamics and chemistry:
Stable aluminium and steel rail stand material
Additional mounting with table clamp possible as standard
Support rings in several diameters are standard and included in the scope of delivery
- ⇒ Ideal for securely holding beakers, Erlenmeyer flasks and other glassware
- ⇒ Maximum safety, especially when handling hot liquids

Electricity theory:
All voltages are limited to 12 V
Low-voltage power supply units for student experiments are RiSU-compliant
Our concept for the student experiments: 1 separate basic box with stand and set-up material - multifunctional use!

The SEK rail stand material - basic box for...
- ... SEK Mechanics 1
- ... SEK Dynamics
- ... SEK Vibrations and Waves
- ... SEK Forces and Torque
- ... SEK Heat 1
- ... SEK Optics 2
NTL rail stand material - stable and robust made of aluminium and stainless steel
NTL-Experiment manuals:
Of course, we also offer the corresponding experiment instructions for all student experiment boxes. The wording of the experiment instructions available for all experiments is ideally matched to the material composition of our student experiment boxes.
NTL student experiment boxes and the associated experiment manuals lead simply, quickly and safely to the desired result and thus guarantee the achievement of the set learning objectives.
Our experiment manuals are formulated and structured in such a way that students can set up and carry out experiments independently. Of course, all the experiments we offer can also be used in station mode; we regularly organise experimental seminars for teachers in which we work with our student material in station mode, among other things.

NTL-Student experiment manuals
Ideally matched to the compositions of the boxes
Adapted to the curricula and education plans of the federal states
Developed by and with experienced educators
Available as a printed version or digitally as a PDF document
Please note:
The experiment manuals are not included in the boxes. They must be purchased separately in the required quantity.
You will find the experiment manuals in the accessories for each SEK.
Directly below you will find all available student experiment boxes. Clicking on them will take you to the respective detail page of the SEK.
