Quick answer. Capacity and readability decide every balance purchase, and this listing gives neither, so ask for both in writing against any LB code you are considering. They trade against each other: readability is the smallest increment the display resolves, capacity is the largest mass the pan will take, and no single balance is excellent at both. That is why a laboratory ends up with two or three rather than one. Specify from the smallest mass you need to weigh accurately, not the largest you might ever put on the pan, and the rest of the choice follows.
Ray Export lists 24 balances, scales and weight sets in the LB series, LB-0001 to LB-0025, across three pages. Two numbers decide every balance purchase, and the listing gives neither: capacity and readability. Ask for both, in writing, for any code you are considering. They trade against each other, so there is no single balance that covers a whole laboratory.
| Type | Codes | Items as listed |
|---|---|---|
| Analytical balances | LB-0001, LB-0008, LB-0024 | Analytical scale, electronic analytical balances, analytical balances. Three separate entries; ask what distinguishes them |
| Precision balance | LB-0015 | Precision balance |
| Digital bench and platform scales | LB-0006, LB-0007, LB-0014, LB-0016, LB-0017, LB-0020 | Digital platform weighing scale, digital weighing scale, platform balance, weighing balances, weighing scale, laboratory balances |
| Mechanical and beam balances | LB-0002, LB-0004, LB-0011, LB-0013, LB-0022 | Balance beam scales, countertop mechanical scales, mechanical scales, pan balance, triple beam balance |
| Spring balance | LB-0021 | Spring balances, which measure force rather than mass |
| Weights and calibration | LB-0003, LB-0009, LB-0010, LB-0012, LB-0018, LB-0019, LB-0025 | Calibration weight, laboratory weights, measuring weights, metric weights, weight box, analytical balance weight, calibrated weight |
There is no LB-0005 in the sequence, and LB-0023 is a vernier caliper, which belongs with the measuring instruments rather than the balances. Many of the product names in this listing also end with a stray number, for example "Weighing Scale - 4453"; that number is not a model number or a capacity, so do not quote it as part of the specification.
Readability is the smallest increment the balance displays; capacity is the largest mass it will take. A balance cannot be excellent at both, so match the instrument to the smallest mass you need to weigh accurately, not the largest.
| Class of balance | Typical job | What to ask for |
|---|---|---|
| Analytical | Weighing to prepare a standard solution, gravimetric analysis, anything whose result is reported | Readability, capacity, whether a draught shield is fitted, and whether calibration is internal or by external weights. An analytical balance also needs a stable, vibration-free bench away from draughts and direct sun, so check the installation before you order. |
| Precision | General preparation, reagent weighing, sample weighing where the last decimal place is not reported | Readability and capacity, and whether it has a below-balance weighing hook or a density kit if you need those |
| Bench and platform | Bulk weighing, receiving stores, larger glassware and equipment | Capacity, platform size, and whether the display can be mounted separately |
| Mechanical, beam and pan | Teaching the principle of weighing, and any bench with no reliable power | Capacity and the smallest division on the beam. These need no power and hold their accuracy indefinitely, which is why they still earn a place in a teaching lab |
| Spring balance | Physics practicals measuring force | Range in newtons and in grams, and the division. Note this is a force meter: it is not a substitute for a mass balance and its reading changes with local gravity |
Seven of the 24 codes are weights or weight sets, and a weight is only useful if its tolerance class suits the balance it is checking. Calibration weights are graded into classes, and a weight whose tolerance is coarser than the balance's readability cannot verify that balance. So on any weight enquiry:
Ask for the supply voltage and whether the balance will run on battery; whether a calibration certificate for the balance itself is available and what the recalibration interval is; whether the display reads in the units your method uses; and what is in the box, specifically the pan, draught shield, adapter and any software. Any accuracy figure quoted for these balances is confirmed in writing on the quotation, so ask for its basis and verify it against your own requirement before ordering.
Further balances and scales, including a weight box and slotted weight sets, are under Lab Balances and Scales. Physical, platform and torsion balances for pharmaceutical work are under Pharmaceutical Lab Equipments. Calipers and micrometers are under Measuring Lab Instruments and, with more variants, under Lab Equipments. Ovens, furnaces and baths used alongside gravimetric work are under Analytical Lab Instruments. Parent range: Scientific Lab Equipments.
Give the smallest mass you need to weigh accurately and the largest mass you will put on the pan, and the supplier can match the balance to both. For weights, give the class and the balance they will check, for example Electronic Analytical Balances (LB-0008) at a stated readability, with a weight set of matching class. Contact Ray Export for prices, specifications and certificates.
Readability is the smallest increment the balance displays - the last digit - and capacity is the largest mass it will accept. A balance cannot be excellent at both, because the mechanism that resolves a tenth of a milligram is not the one that carries several kilograms. So specify from the smallest mass you need to weigh accurately: if a method needs a 0.1 g addition read reliably, that sets the readability, and the capacity only has to cover your largest routine sample plus its container. Buying for the largest mass first is the usual way a laboratory ends up unable to weigh its standards.
Ask what distinguishes them, because the listing does not say. The analytical scale (LB-0001), the electronic analytical balances (LB-0008) and the analytical balances (LB-0024) are three separate entries with near-identical names, so the comparison has to come from the specification rather than the listing. Request four things for each: the readability, the capacity, whether a draught shield is fitted, and whether calibration is internal or by external weights. The shield matters because a balance resolving the fourth decimal place will not settle in moving air, and internal calibration saves buying and maintaining a weight set.
Two reasons, and both are practical. First, teaching: a beam or pan balance shows the principle of weighing in a way a digital display cannot, which is why it still earns bench space in a teaching laboratory. Second, power: mechanical balances need no supply at all, so they work on a bench with no socket or where the supply is unreliable, and they hold their accuracy indefinitely with no recalibration of electronics. When you order one, ask for the capacity and the smallest division on the beam, since the division is the mechanical equivalent of readability and sets what the instrument can actually resolve.
No. A spring balance is a force meter, not a mass balance, and it is listed here for physics practicals that measure force. Its reading depends on local gravity, so the same object gives a different reading in a different place, which is exactly what a mass balance is built to avoid. Use it for pulling, hanging and force experiments, and keep sample weighing on a proper balance. When ordering, ask for the range in newtons and in grams and the division, since a force meter graduated too coarsely for your experiment is no more useful than the wrong range.
By class, because the class is the specification. Seven of the 24 codes here are weights or weight sets, and a weight is only useful if its tolerance suits the balance it checks: a weight whose tolerance is coarser than the balance's readability cannot verify that balance at all. So state the class you need and the standard it is graded against. If you do not know the class, give the readability of the balance the weights will check and ask for a recommendation rather than ordering a weight box by capacity alone. Ask also whether a calibration certificate accompanies the set.
Four things. The supply voltage, and whether the balance will also run on battery, which matters for field work and for rooms with interruptions. Whether a calibration certificate for the balance itself is available and what recalibration interval the manufacturer expects. Whether the display reads in the units your method uses. And what is in the box - specifically the pan, the draught shield, the adapter and any software - since those are the items most often assumed and then missing. Any accuracy figure quoted is confirmed in writing on the quotation, so ask for its basis and check it against your own requirement.

Capacity, readability, pan size and division are not published anywhere on this listing, so all of them have to be requested in writing per code before an order is placed; the same applies to weight classes and the standards they are graded against. Any accuracy figure quoted is confirmed in writing on the quotation: ask for its basis and check it against your own requirement. No price is quoted on this page, as prices are issued as dated written quotations. Defects visible in the listing itself: there is no LB-0005 in the sequence; LB-0023 is a vernier caliper, which belongs with the measuring instruments rather than with the balances; several product names end with a stray number, such as the 4453 on a weighing scale entry, which is neither a model number nor a capacity and should not be quoted as part of a specification; and six digital bench and platform entries carry near-identical names, which makes them impossible to tell apart from this page alone.
