Burette Set: Uses, Parts, 100 mL vs 150 mL & Buying Guide for Hospitals
A burette set is an IV set with a graduated chamber between the fluid bag and the patient line. The chamber holds a measured volume of fluid, which is why doctors, nurses and paediatric wards use it when they need tighter control over how much fluid is available to the patient.
If you are a hospital, clinic, nursing home or distributor, this guide covers what you need to order the right set the first time: uses, parts, 100 mL vs 150 mL, drop factor and a ready-to-use enquiry format.
Always specify chamber capacity, drop factor and venting separately. Never order by the words “burette set” alone.
What Is a Burette Set?
A burette infusion set (also called a burette IV set, IV burette set or measured-volume set) is a single-use IV administration set with a graduated chamber that holds a measured volume of infusion solution.
Single-use gravity burette sets are covered by ISO 8536-5, a separate standard from ordinary gravity IV sets (ISO 8536-4). A burette set is therefore not just another name for a standard IV set.
The chamber gives volume control. It does not decide the dose or infusion rate; those remain clinical decisions.
Burette Set Uses
Burette sets are used where clinicians want a defined volume of fluid within the line, commonly in:
- Neonatal and paediatric care
- Geriatric care
- Controlled gravity infusions
- Intermittent medication administration (in suitable systems)
- Selected pump-compatible applications, where the set is specifically approved for the pump
Why Paediatric Wards Use Burette Sets
Children, especially neonates, need careful management of fluid volumes. A measured chamber lets staff work with a defined quantity instead of relying only on the large primary container. Many paediatric sets combine a burette with a 60 drops/mL microdrip.
This does not mean every child needs a burette set. The choice is made by the treating clinician and hospital protocol.
Main Parts of a Burette IV Set
| Component | Function | What to Specify |
|---|---|---|
| Piercing spike | Connects to the infusion container | Vented or non-vented? |
| Air vent (where provided) | Supports container venting | Closable? Filtered? |
| Graduated burette chamber | Holds a measured volume | 100 mL, 150 mL or other? |
| Float / shut-off valve (where provided) | Fluid/air control | Required or not? |
| Drip chamber | Lets staff see drops | 60 gtt/mL (micro) or other? |
| Fluid filter (where provided) | Filtration | Micron rating, if needed |
| Tubing | Carries fluid to IV access | Material, length, priming volume |
| Roller clamp | Manual flow control | Type supplied |
| Injection / access ports | Extra line access | Number and type |
| Terminal connector | Connects to IV access | Luer lock, rotating luer, etc. |
Features differ by manufacturer and catalogue number. Compare exact product codes, not product names.
100 mL vs 150 mL Burette Set
Both capacities are sold by major manufacturers. For example, Romsons offers a 100 mL paediatric measured-volume set (Pedia Drip Plus, 60 drops/mL), while Baxter (Buretrol) and B. Braun (Dosifix) offer 150 mL sets.
| 100 mL Burette Set | 150 mL Burette Set | |
|---|---|---|
| Typical use | Smaller-volume paediatric / neonatal use, as per clinician | Larger measured volume, paediatric and general use, as per clinician |
| Example | Romsons Pedia Drip Plus | Baxter Buretrol, B. Braun Dosifix |
| Common drop factor | 60 gtt/mL (verify per SKU) | 60 gtt/mL (verify per SKU) |
| What still varies | Venting, filter, connector, tubing | Venting, filter, connector, tubing, pump compatibility |
Neither is universally better. The right capacity depends on your hospital’s approved protocol. Do not let a supplier swap 100 mL for 150 mL without clinical approval.
Is a Burette Set the Same as a Microdrip Set?
No. They are two separate specifications:
- Burette = the measured-volume chamber
- Microdrip = the drop factor (60 drops/mL)
Many burette sets are also 60 gtt/mL, but this must be confirmed for each product. When ordering, write: “Burette capacity: 150 mL; Drop factor: 60 gtt/mL.” Do not write only “micro burette set.”
Burette Set vs Standard IV Set
| Feature | Standard Gravity IV Set | Burette IV Set |
|---|---|---|
| Graduated measured-volume chamber | No | Yes |
| Main purpose | Basic fluid delivery | Measured volume control |
| ISO standard | ISO 8536-4 | ISO 8536-5 |
| Can one replace the other? | Not automatically; needs clinical approval | Not automatically; needs clinical approval |
Some burette sets are gravity-only, while others are designed for specific infusion pumps. Never assume pump compatibility; check the exact product.
Burette Set Bulk Buying Checklist
Before placing a hospital or distributor order, confirm:
- Chamber capacity (100 mL / 150 mL)
- Exact drop factor (gtt/mL)
- Vented or non-vented spike
- Tubing material and length (DEHP-free / PVC requirement, if any)
- Filter requirement and micron rating
- Float / auto shut-off valve, if required
- Access ports and connector type
- Gravity or pump use (and exact pump model)
- Sterile, single-use, individually packed
- Batch number, expiry and minimum remaining shelf life
- Applicable standard and regulatory documents (CDSCO / Medical Devices Rules, 2017)
- Pieces per pack and per case
- Quantity, delivery city and schedule
- Whether brand substitution is allowed
