Laboratory Metal bath Series Manufacturer

Shanghai Qiujing Biochemical Reagent & Instrument Co., Ltd. manufactures the Qiujing Pure Series of metal bath and dry block instruments for laboratories that need stable temperature control without water. The range covers a dry bath unit, an actively cooled metal bath plate, heating and cooling temperature-controlled mixers, a covered heatable mixer, and microplate thermostatic oscillators in single-plate and six-module formats. Our brand was established in 1988 and the company has developed and produced laboratory instruments in Shanghai since then, with CE and ISO 13485 certification behind the product lines and a full-process quality system covering incoming material, in-process and finished-product inspection.

A metal bath module replaces water as the heat transfer medium with a machined block that holds tubes or microplates directly. That removes evaporation, spillage and refill routines from the bench and makes setpoint behaviour the main engineering question rather than water quality. As a Laboratory Metal bath Series manufacturer we build the range around that working principle: solid block contact, PID control, and a format that matches the vessel you actually load.

The Qiujing Pure Series Metal Bath Range

Seven instruments make up the current series. Each one answers a different bench task, from simple tube incubation to temperature-controlled mixing and plate-based batch work.

Where Dry Block Instruments Fit

The series is used wherever a protocol needs a defined block temperature held for a defined time, with no water contact and no evaporation loss. PID control is the normal control approach on these instruments, and block uniformity within ±0.1 °C is a realistic target when the controller, block and loaded vessels are matched as one system. We confirm that figure against your actual tube or plate format rather than quoting it from a single specification line.

• PCR and nucleic acid preparation — block incubation, denaturation and enzyme step control.
• Enzyme and protein assays — reproducible incubation temperatures without water bath cross-contamination.
• Clinical and diagnostic testing — plate formats for ELISA and comparable methods, extended to six-module batch work with MP-H6.
• Food, environmental and industrial testing — sample preparation and component analysis in quality-control laboratories.
• Biotechnology and pharmaceutical development — the repeatability required for sample preparation and process monitoring.

Where a protocol genuinely depends on a liquid medium — for example, evaporation-sensitive work in open vessels or methods validated on water — the Laboratory Water Baths Series remains the appropriate choice inside our instrument programme. Metal bath and water bath instruments are complementary, and liquid handling sits alongside both, which is why the Pipetting range and the metal bath series are frequently specified for the same bench.

Specifications We Configure

Temperature performance is only one part of a usable metal bath. Block geometry, vessel fit and control behaviour determine whether a validated protocol transfers to a second bench, so we treat them as a single configuration task.

• Block format and well geometry — matched to 0.2 mL, 0.5 mL, 1.5/2.0 mL microtubes, larger tubes or standard microplates.
• Working temperature — the setpoint window your protocol needs, including cooling where the method requires sub-ambient holding.
• Uniformity and stability — the block and vessel combination, the load, and the ambient conditions at the bench.
• Heat-up and cool-down behaviour — relevant where a step change or a rapid cool-down sits inside the protocol.
• Control and display — microprocessor and PID control, timer and step settings, and how quickly an operator can read and change them.
• Mixing parameters — speed range, orbit and duty cycle for MIX-100, MIX-100L, MIX-100C, MP-H and MP-H6.
• Electrical supply — voltage and frequency for the destination laboratory, and the low-voltage design used in the H-100 dry bath unit.

Covered Work, Mixing and Plate Formats

Covered incubation

CH-100 and CL-100 combine a heated block with a cover to reduce condensation and temperature loss above the vessel. MIX-100C adds a heated lid to the mixing function, which matters for small volumes and for incubation steps that run long enough for condensed liquid to change the reaction concentration.

Temperature-controlled mixing

MIX-100 and MIX-100L are multi-purpose constant temperature mixers built for protocols that require heating or cooling and agitation at the same time. We confirm the speed range and working temperature against the vessel size and the fill volume, because both influence how uniformly the contents reach the block setpoint.

Microplate throughput

MP-H handles a single plate with microprocessor and PID control. MP-H6 extends the same function across six modules for laboratories running plates in batch. The choice is a throughput decision, and we size it against the number of plates per run and the incubation time rather than against bench space alone.

Installation, Integration and Utilities

Every instrument in the series is a bench unit with its own controller, so installation is straightforward: a level surface, clearance for airflow on the cooling models, and a mains supply matching the configured voltage and frequency. We confirm the destination supply before production so that the delivered configuration meets the local power conditions without an external transformer.

Where an application needs to sit inside a larger workflow, the relevant interface questions are the temperature programme, the timing, and how the instrument is used alongside other bench equipment. We review those points during configuration rather than assuming a standard catalogue variant will fit a specific data or control requirement.

Quality, Acceptance and Documentation

Our quality system is certified to ISO 13485 and our products carry CE certification, supported by an in-house test laboratory and a number of technical patents. Production runs through incoming raw-material inspection, in-process testing and finished-product inspection, so accuracy and stability are checked at each stage rather than at the end of the line.

• Block temperature performance verified on the finished assembly, not on the controller alone.
• Order-specific acceptance checks agreed before shipment for OEM and ODM projects.
• Shipment documentation, product identification and packaging agreed with the order scope.
• CE and ISO 13485 certificates available as part of the commercial documentation set.

OEM/ODM and the Laboratory Metal bath Series We Supply

We work as an OEM/ODM partner as well as a catalogue manufacturer. Custom block drilling for your tube or plate set, specification adjustment, branding and packaging are handled through the same engineering process used for the standard range. Customisation runs from requirement consultation and solution or sample confirmation through to precision manufacturing, global delivery and after-sales support, with a standard quoted lead time of 10 working days for catalogue configurations.

Serviceability is designed in: block replacement, controller settings and routine cleaning are bench-level tasks, and we support long-term operation with spare parts, operating guidance and troubleshooting for overseas partners.

Information We Use to Configure Your Solution

A useful quotation for a metal bath project is built from the working point, the vessel and the production target — not from a model number alone. These are the inputs our engineers work through with you.

Send those inputs and we respond with a configuration, a sample route where applicable and a delivery schedule. For a single reference point in the range, the Qiujing Pure Series Dry Bath Unit H-100 shows how the dry block format is realised, and the wider Laboratory Instruments programme covers the centrifuges, stirrers, balances, photometers and pH meters that accompany it on the bench.

Frequently Asked Questions

What is the difference between a dry bath and a water bath?

A dry bath transfers heat through a machined metal block that holds tubes or plates directly, so there is no water to evaporate, spill or refill. A water bath uses a liquid medium and suits protocols validated on water. We manufacture both instrument families, and we recommend the format that matches the method rather than the bench habit.

Can you supply custom block drilling for our tube or plate format?

Yes. Custom block geometry is part of our OEM/ODM scope. We work from the vessel drawing or a physical sample, confirm the well diameter and depth, and verify the fit before production. Samples can be provided for performance verification before a bulk order.

Which models support both heating and cooling?

L-100 provides a cooled metal bath plate, MIX-100 and MIX-100L combine heating or cooling with mixing, and CH-100/CL-100 bring heating and cooling to a covered block format. The H-100 dry bath unit is a heating instrument for straightforward incubation work.

Which model suits microplate work?

MP-H handles one plate with microprocessor and PID control. MP-H6 carries six modules for laboratories processing plates in batch. We size the choice against plates per run and incubation time, since a longer hold can shift the throughput calculation towards the six-module format.

How is temperature uniformity addressed across the block?

Uniformity depends on the controller, the block material and mass, the vessel fit and the ambient conditions. PID control is used across the range, and uniformity within ±0.1 °C at the block is a realistic target when those elements are matched. We confirm the value for your tube or plate combination during configuration.

What quality certification do you hold, and how do you support overseas customers?

Our quality management system is certified to ISO 13485 and our products hold CE certification, backed by an in-house test laboratory and full-process inspection from raw material to finished product. Products are exported to international markets and supported with technical consultation, operating guidance, spare parts and troubleshooting for overseas partners.
