Quick answer. Order by practical, not by line item. This first school listing, SLE1-0001 to SLE1-0090 (D to H), splits apparatus that is used together into separate codes, so a buyer who orders one line at a time ends up short or doubled. The rectangular glass block, glass prism and semi-circular blocks are separate codes but one refraction practical; the dissecting kit (SLE1-0008) may already contain the forceps, needles and scissors that are also listed singly; and the gold leaf electroscope (SLE1-0048) has its spare gold leaf as a separate line. Build each class set from the practical outwards, then check for overlaps.
This is the first of three alphabetical listings in Ray Export's school laboratory range, covering codes SLE1-0001 to SLE1-0090 across nine pages, broadly from D to H. It holds dissection instruments, optical blocks and prisms, electrostatics and cell apparatus, biology models, hygrometers and hydrometers, and the glassware and protective wear that go with school practicals.
| Group | Codes seen | Items as listed |
|---|---|---|
| Dissection instruments | SLE1-0006 to SLE1-0010 | Dissecting board, dissecting forceps, dissecting kits, dissecting needles with plastic handles, stainless steel dissecting scissors |

| Electricity and electrostatics | SLE1-0001, SLE1-0003, SLE1-0005, SLE1-0048, SLE1-0049, SLE1-0089 | Complete Daniel cell, demonstration transformer with two secondary coils, mounted diode, gold leaf electroscope, spare gold leaf, AC/DC dynamo working model |
| Biology models | SLE1-0082 to SLE1-0084 | Animal meiosis model, plant mitosis model, plant meiosis model |
| Measurement | SLE1-0086 to SLE1-0088 | Hydrometer, wet and dry hygrometer, digital hygrometer with temperature |

| Protective wear | SLE1-0046, SLE1-0047 | Rubber gloves, disposable latex gloves |
Ray Export's school laboratory range is catalogued alphabetically and split across three listings. Nothing in the navigation says where one stops and the next begins, so this is the map:
| Listing | Codes | Pages | Alphabetical span |
|---|---|---|---|
| School Laboratory Equipments 1 | SLE1-0001 to SLE1-0090 | 9 | D to H, from Daniel Cell to Hygrometer |
| School Laboratory Equipments 2 | SLE2-0001 to SLE2-0066 | 7 | I to O, from Incubator Electrical to Oven Electrical |
| School Laboratory Equipments (third listing) | SLE3-0001 to SLE3-0111 | 12 | P to W, from Pencil Jockey to Wheel and Axle |
There is no A to C section in the SLE series. Items whose names begin with those letters, such as ammeters, balances and burners, are catalogued in other ranges on this site rather than here, so search by item rather than by letter if you cannot find something.
| Decision | What to confirm |
|---|---|
| Latex or nitrile gloves | SLE1-0047 is listed as disposable latex. Latex can cause allergic reactions in a minority of users, so many schools now specify nitrile instead. Ask whether a nitrile equivalent can be supplied if that is your policy. |
| Hand lens style | SLE1-0050 and SLE1-0051 differ in the handle and case rather than the optics. Ask for the magnification and lens diameter for either code. |
| Hygrometer type | The wet and dry hygrometer (SLE1-0087) needs a wick and distilled water and teaches the principle; the digital version (SLE1-0088) gives a direct reading and also shows temperature. For an assessed practical, the wet and dry pattern is usually the one specified. |
| Dissecting kit contents | SLE1-0008 is listed as a kit while SLE1-0006, SLE1-0007, SLE1-0009 and SLE1-0010 are individual instruments. Ask for the kit contents list so you do not order items twice. |
| Optical block set | The rectangular block, prism and semi-circular blocks are separate codes. A standard refraction practical usually needs all three, so quote them together. |
| Metal foil | SLE1-0090 covers zinc, copper and lead in one code. State which metal and what thickness you need. Lead requires handling precautions in a school lab. |
Give the code, the item name and the quantity per class set, for example Gold Leaf Electroscope (SLE1-0048) or Dissecting Kits (SLE1-0008), and contact Ray Export for prices and class-set pricing. Parent range: Scientific Lab Equipments.
Not necessarily, and the listing does not say. SLE1-0008 is listed as dissecting kits, while the dissecting board, dissecting forceps, dissecting needles with plastic handles and stainless steel dissecting scissors appear as individual codes within SLE1-0006 to SLE1-0010. Ask for the contents list of the kit before you order, then add individual instruments only for what the kit leaves out or for spares. That way you do not pay twice for forceps and scissors that may already sit in every kit.
A standard refraction practical usually needs all three shapes, so quote them together: the rectangular glass block, the glass prism and the semi-circular glass blocks, listed as separate codes within SLE1-0042 to SLE1-0044. The rectangular block shows lateral displacement, the prism shows deviation and dispersion, and the semi-circular block is the usual shape for finding the critical angle. Diffraction gratings (SLE1-0004) sit in the same optics group if your scheme also covers diffraction, and the two hand lenses (SLE1-0050, SLE1-0051) differ in handle and case rather than optics.
Choose by what the lesson needs. The wet and dry hygrometer (SLE1-0087) needs a wick and distilled water, and it teaches the principle: evaporation cools the wet bulb, and the difference between the two readings gives the relative humidity from a table. The digital hygrometer with temperature (SLE1-0088) gives a direct reading and also shows temperature. For an assessed practical the wet and dry pattern is usually the one specified, so check your syllabus before ordering the digital version alone.
Two codes are listed: rubber gloves (SLE1-0046) and disposable latex gloves (SLE1-0047). Latex can cause allergic reactions in a minority of users, which is why many schools now specify nitrile for class use. If nitrile is your policy, ask whether a nitrile equivalent can be supplied, and give the sizes and the quantity per class set. For the rubber gloves, ask what they are made from and whether they are intended for handling chemicals or only for general bench work.
The group covers a complete Daniel cell, a demonstration transformer with two secondary coils, a mounted diode, a gold leaf electroscope, a spare gold leaf and an AC/DC dynamo working model, under SLE1-0001, SLE1-0003, SLE1-0005, SLE1-0048, SLE1-0049 and SLE1-0089. Gold leaf is thin and tears easily in student hands, so it is worth ordering the spare leaf with the Gold Leaf Electroscope (SLE1-0048). Ammeters and other items beginning A to C are catalogued in other ranges on this site, not in the SLE series.
SLE1-0090 covers zinc, copper and lead foil under one code, so the code alone does not identify what you want. State which metal, what thickness and how much of each. Lead requires handling precautions in a school lab, so plan gloves and hand washing for any practical that uses it. The same sundries group lists a deflagrating spoon with lid (SLE1-0002) and glass stirring rods (SLE1-0045), which can go on the same enquiry with the quantity per class set.
