Laboratory Water Baths Series Manufacturer

Laboratory Water Baths Series: What Qiujing Supplies

Shanghai Qiujing Biochemical Reagent & Instrument Co., Ltd. is a Laboratory Water Baths Series manufacturer operating from Songjiang, Shanghai, China. Our range covers three bath families used for incubation, reagent warming and constant-temperature reaction work: the WB-2 thermostatic water bath pot, the WB-5 bath pot, and the HW-S multi-point stirring water bath in 1, 2, 4, 6 and 8 positions.

A water bath holds a sample or vessel at a steady temperature for a prolonged period rather than applying a short heating step. That is why it is used instead of an open flame when flammable substances are heated, and why it supports reactions that need sustained heat. We manufacture, test and pack these units as part of our Laboratory Instruments programme, then deliver them to laboratories, distributors and OEM partners.

Our Water Bath Range and Where Each Model Fits

Each family answers a different working pattern. Single-vessel incubation and reaction work is handled by the thermostatic pots; parallel vessel handling under one set temperature is handled by the stirring baths. Model-level capacity, set-point range and stirring speed are confirmed against your workload when the proposal is prepared.

Detailed configuration for the WB-2 family is listed on the Thermostatic Water Bath Pot WB-2-1/WB-2-2/WB-2-3 model page, and the stirring positions on the Multi-Point Stirring Water Bath HW-S-1P/2P/4P/6P/8P model page.

Application Fit in Laboratory Workflows

Water baths sit in the wet-bench workflow wherever a vessel must be held at temperature while the rest of the protocol continues. Microbiology incubation, biochemical assay preparation, reagent warming before use, media melting and viscosity-sensitive transfers are the most common placements.

• Research and teaching laboratories — general incubation and preparation steps where a stable, repeatable set point matters more than throughput.
• Medical and clinical testing — sample conditioning and reagent preparation inside documented procedures.
• Biotechnology and pharmaceutical — reaction support and sample preparation where temperature consistency across the batch is recorded.
• Food, environmental and industrial QC — sample pretreatment and dissolution steps in testing laboratories.

Because flammable materials are frequently handled nearby, the liquid-heating principle of the bath is applied instead of direct flame contact. Where a customer works with media other than water, the fluid, concentration and working temperature are agreed before the wetted-part specification is fixed.

Critical Specifications We Confirm Before Quoting

Two baths with the same nominal set point can behave very differently once racks, flasks and cold samples enter the chamber. The variables below decide whether a model actually fits the protocol, so we settle them with your technical contact before the configuration is released.

Multi-Point Stirring Baths for Parallel Work

The HW-S series combines U-shaped heating with water bath circulation, so heat distribution and stirring act on the same chamber. Position counts of 1, 2, 4, 6 and 8 let a laboratory scale a method from a single vessel to a full run without changing the set temperature between positions.

For distributors, the practical benefit is one chassis platform covering several catalogue entries, which simplifies stocking and spare-part planning. For the end user, it keeps vessels at the same condition throughout a series, which is the point of a parallel method.

Controls, Utilities and Installation

Control interface expectations differ by market, so the operator panel, display language and setting method are part of the order specification rather than an afterthought. Where a bath is used inside a regulated environment, we agree how the unit is identified, set and logged, and whether the customer needs the temperature to be independently verified at the bench.

• Supply voltage, frequency and plug type matched to the destination market.
• Bench position planned with access for filling, emptying and vessel loading.
• Start-up procedure and set-point routine documented for the operators who will run the unit.
• Protective measures for hot surfaces, spills and the chemicals in use handled as part of the bench risk assessment.

Quality Control, Documentation and Serviceability

Qiujing operates a quality management system certified to ISO 13485 and holds CE certification for its instrument range. Inspection covers raw material intake, in-process checks and finished-product verification in our own test lab, so accuracy and repeatability are confirmed on the assembled unit rather than inferred from components.

Shipping documentation, model identification and configuration details are aligned to the order, since these records drive both customs clearance and later service. Routine maintenance is straightforward: keeping the chamber and wetted parts clean, checking the liquid level, and inspecting the stirring positions of the HW-S series for uninterrupted rotation.

OEM/ODM Customization, Packaging and Delivery

We build OEM and ODM programmes around customer drawings or samples, and around market requirements that differ from our standard catalogue. Supported changes include product design adjustments, specification changes, appearance and branding, and packaging configuration. A sample can be supplied for performance verification before bulk production is confirmed.

Standard lead time is 10 working days, with the exact schedule confirmed once the model, quantity and customization scope are settled. Units leave our factory in protective packaging suitable for international freight, and after-sales support covers product consultation, operating guidance and troubleshooting for overseas partners.

Frequently Asked Questions

Which models make up the Qiujing laboratory water bath range?

The range covers the WB-2-1, WB-2-2 and WB-2-3 thermostatic water bath pots, the WB-5 bath pot, and the HW-S multi-point stirring water bath in 1, 2, 4, 6 and 8 positions. Each family is produced under the Qiujing brand and can be adapted for OEM or ODM programmes.

Can a water bath be supplied as an OEM or ODM build with our own branding?

Yes. We support OEM and ODM projects based on customer drawings or samples, including specification adjustment, appearance customization and packaging design. The customization scope is agreed before production, and samples are available for evaluation.

When should a multi-point stirring bath be used instead of a standard bath pot?

When several vessels must be stirred at the same temperature in one run, the HW-S series keeps heating, circulation and stirring inside a single chamber. Single-vessel incubation, warming and reaction steps are normally served by the WB-2 or WB-5 thermostatic pots.

How is temperature quality verified before shipment?

Incoming materials, in-process assembly and finished instruments pass through staged inspection in our own test lab under a quality system certified to ISO 13485, with CE certification held for the instrument range. Test results are attached to the production record for the order.

What is the typical delivery time for a water bath order?

Standard lead time is 10 working days. The confirmed schedule depends on model, quantity and the extent of OEM/ODM customization, and is stated once the order details are fixed.

What applies after the unit is installed?

We provide operating guidance, product consultation and troubleshooting for overseas customers, plus configuration records that make spare parts ordering and service straightforward. Routine upkeep centres on chamber cleanliness, liquid level and, on the HW-S series, free rotation of the stirring positions.
