Acid and bicarbonate concentrates
We supply acid and bicarbonate concentrates to registered renal units only, in canisters and cartridge formats for compatible proportioning systems. Orders are handled from Midrand with next-day courier to major centres and scheduled deliveries further afield.
What these concentrates are
Acid and bicarbonate concentrates are ordered by renal units for use with dialysis delivery systems that proportion concentrate with treated water according to the machine setup in the unit. We supply the concentrate formats commonly requested by registered renal units, including canisters and dry bicarbonate cartridges, for routine facility purchasing only.
This page is about supply and ordering rather than treatment use. Because machine configuration differs between units, concentrates must be matched to the unit's existing proportioning method, connector style and storage arrangements before dispatch. We do not supply to the public and we do not advise on patient-specific product choice.
- Available supply formats include liquid acid concentrate in canisters.
- Dry bicarbonate is supplied in cartridge format for compatible cartridge-based systems.
- Some units may require matching documentation on connector type, label wording and pack format before ordering.
Formats, sizes and working limits
Concentrates are not a one-size-fits-all item. The right option depends on the dialysis machine or central delivery arrangement already in place at the renal unit. Canisters are generally suited where the unit uses liquid concentrate feed and has the correct pick-up fittings, while cartridges suit systems designed specifically for dry bicarbonate cartridge loading.
Working limits are mainly about compatibility, handling and storage rather than treatment settings. A cartridge system must use the cartridge size and fitting type specified for that system, and canisters must match the unit's connectors and concentrate ratio requirement. Mixing formats, transferring contents between containers, or using an unconfirmed connector setup is not suitable.
- Canister options are selected by container size, connector arrangement and concentrate type.
- Cartridge options are selected by cartridge diameter, height and machine compatibility.
- Units should order the exact format already validated for their facility setup.
- Products should remain sealed until use and should not be decanted into other containers.
Where these products suit, and where they do not
These concentrates suit registered renal units that already run a fixed procurement process, have trained operators, and can receive, store and rotate stock correctly. They are a practical fit for hospital-based renal areas, day units and other authorised treatment facilities that need repeat supply into Johannesburg, Pretoria, Durban, Cape Town and other major centres by courier, with scheduled runs where needed.
They do not suit home use, public walk-in purchase, or facilities without a confirmed machine setup and receiving process. They are also not suitable where there is no controlled storage area, no batch receiving procedure, or no way to separate incoming stock by type and date. In coastal areas the storage room should be kept dry and orderly because moisture can affect outer packaging over time if cartons are left open, this matters especially for cartridge stock.
- Suitable for registered renal units only.
- Suitable where the unit can confirm machine compatibility before ordering.
- Not suitable for patient purchase or collection by the public.
- Not suitable where the facility cannot receive and inspect consignments promptly.
Site requirements and receiving at the unit
Before placing a regular order, the unit should confirm how and where concentrate stock will be received and stored. Canisters need a clean, level storage area away from heat sources and direct sun. Cartridges should be kept dry in their original cartons until needed. For larger orders, make sure the receiving area can handle the carton count and has enough floor space to keep acid and bicarbonate lines separate during checking.
If your unit is in a business park or hospital campus with restricted access, tell us about loading bays, delivery windows and sign-in requirements when you enquire. Around Midrand, Johannesburg and Pretoria this helps avoid missed handovers. For outlying towns and coastal routes, scheduled delivery planning is often the better option if same-day receiving staff are limited.
- Indoor storage only, in a clean and dry room.
- Keep products in original sealed packaging until required by the unit.
- Separate acid concentrate, bicarbonate cartridges and disinfectants by clearly marked shelf or pallet space.
- Record batch details on receipt according to the unit's own procedure.
Care, storage and stock rotation
Good stock care starts with tidy receiving and clear rotation. Place newer stock behind older stock and issue oldest suitable stock first. Cartons should stay off damp floors and away from leaking pipes or wash areas. In buildings affected by power cuts it helps to check that storerooms remain ventilated and that access control does not delay urgent receiving after hours.
Do not stack canisters higher than the packaging allows, and avoid crushing outer cartons of cartridges. If any package arrives damaged, wet or with an unreadable label, set it aside and note it on the receiving paperwork before the consignment is booked in. Small handling errors become a bigger headache later so a quick check at the door saves time.
- Rotate stock first-in, first-out.
- Keep labels visible for batch and expiry checks.
- Do not expose cartons to direct weather during offloading.
- Store away from cleaning chemicals not intended for the same stock area.
What to tell us when you enquire
To quote the correct concentrate format for your renal unit, we need enough detail to match your established setup. The quickest route is the enquiry form on our contact page, with the unit information entered clearly so the supply format can be checked before dispatch. If your requirement is urgent, note your preferred delivery town and receiving times.
Please include whether you need acid concentrate canisters, bicarbonate cartridges, or both, together with the pack format currently used by the unit. It also helps to mention if the delivery point is in Midrand, central Gauteng, or a major centre requiring next-day courier. For scheduled deliveries further afield we can work around your receiving days where possible.
- Name of the registered renal unit and delivery town.
- Whether you require acid concentrate, bicarbonate cartridges, or both.
- Container or cartridge format currently in use at the unit.
- Any connector or compatibility notes used by your procurement team.
- Preferred delivery window, receiving contact role and site access requirements.
- Approximate order pattern for routine monthly planning if applicable.

Questions we get asked
Can you supply concentrates directly to a patient or home address?
No. We supply dialysis consumables to registered renal units only and do not supply to the public.
How do I know whether to order canisters or cartridges?
Order the format already used by your unit's existing dialysis system and procurement setup. If you are enquiring, include the current format and any compatibility notes from the unit.
Do you provide instructions for treatment use?
No. We only assist with supply, storage and delivery information. Product use must follow the renal unit's own procedures and equipment requirements.
