Benchtop Water Circulator 3.4L Overview
The Benchtop Water Circulator 3.4L (model CB100) is a recirculating circulator / chiller from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. Built for closed-circulation heating and cooling, this unit holds a 3.4 L bath and regulates fluid temperature across a −10°C to 80°C range.
A closed circulation cooling system pairs with R-134a refrigerant to pull bath temperature below ambient without an external water feed. Front-mounted, the intake filter removes for fast cleaning, while a standard-equipped drain simplifies fluid changes. Peak flow reaches roughly 6.8 / 8.0 L/min and lift reaches about 3.3 / 4.7 m at 50 / 60 Hz.
Power runs on AC115V at 50/60 Hz, matching standard North American bench circuits. Measuring 180 mm wide by 360 mm deep, the circulator fits a crowded benchtop beside the instrument it feeds. Typical pairings include viscometers, spectrofluorometers, and other apparatus needing stable cooling or heating circulation.
Key Features
- Wide temperature control: regulates the circulating fluid from −10°C to 80°C for both cooling and heating duty.
- Closed circulation cooling: self-contained loop maintains sub-ambient temperatures without a continuous tap-water supply.
- R-134a refrigeration: sealed refrigerant system (GWP 1430) drives the cooling performance.
- Removable intake filter: front-mounted filter pulls out for quick cleaning and uninterrupted flow.
- Standard drain: equipped as standard for straightforward bath emptying and fluid changes.
- Compact 3.4 L bath: delivers up to ~6.8 / 8.0 L/min flow and ~3.3 / 4.7 m head at 50 / 60 Hz from a 180 × 360 mm footprint.
How to Choose the Right Circulator / Chiller
Matching a recirculating circulator to a downstream instrument comes down to a few measurable axes. Weigh each against the apparatus you plan to feed and the bench space available.
- Temperature range: confirm the unit spans your process setpoints; the CB100 covers −10°C to 80°C for combined cooling and heating work.
- Bath capacity: a 3.4 L reservoir suits single benchtop instruments such as viscometers and spectrofluorometers rather than large multi-loop systems.
- Flow and head: verify the pump can move enough fluid against your line restriction; rate and lift here scale with 50 / 60 Hz operation.
- Voltage and power: match site power, as this model is built for AC115V at 50/60 Hz.
- Footprint: a 180 × 360 mm base fits tight benches beside the instrument being cooled or heated.
- Maintenance access: a removable front filter and standard drain shorten cleaning and fluid-change downtime.

Frequently Asked Questions
What temperature range does the Yamato CB100 cover?
The CB100 regulates circulating fluid from −10°C to 80°C, supporting both sub-ambient cooling and heating applications in a single unit.
What is the bath capacity and footprint of the CB100?
The CB100 has a 3.4 L bath capacity. Its compact footprint measures 180 mm wide by 360 mm deep, fitting alongside benchtop instruments.
What voltage and power does the CB100 require?
The CB100 runs on AC115V at 50/60 Hz, matching standard North American laboratory bench circuits.
Does the CB100 need an external water supply for cooling?
No. The CB100 uses a closed circulation cooling system with R-134a refrigerant, so it cools the bath without a continuous tap-water feed.
How is the CB100 maintained?
Maintenance is straightforward. A front-mounted intake filter removes for cleaning, and a standard-equipped drain allows quick bath emptying and fluid changes.
What applications is the CB100 designed for?
