Jiayuan JYH-100 Dry Block Heater (Heating-Only Metal Bath)

Overview

The Jiayuan JYH-100 Dry Block Heater is a precision-engineered, heating-only metal bath designed for consistent thermal incubation of samples in molecular biology, clinical diagnostics, and routine laboratory workflows. Unlike circulating water baths, this dry block system employs solid aluminum heating blocks with optimized thermal conductivity and low thermal mass to deliver rapid, uniform heat transfer directly to sample vessels. Its operation is based on Peltier-free resistive heating controlled by a microprocessor-driven PID algorithm, ensuring stable setpoint maintenance across the full operating range (ambient +5°C to 100°C). The unit is intended for applications requiring reliable, contamination-free heating—such as enzyme activation, DNA denaturation, reagent pre-warming, and sample equilibration—without immersion or condensation risks associated with liquid baths.

Key Features

• High-precision temperature control with ≤ ±0.3°C accuracy at 100°C and ≤ ±0.3°C uniformity across the block surface (measured at 40°C)
• Rapid thermal response: heats from 25°C to 100°C in ≤12 minutes due to efficient aluminum block design and 150 W heating capacity
• 0.1°C display resolution and intuitive keypad interface with real-time temperature readout
• Programmable timer supporting up to 99 hours and 59 minutes, with automatic shutdown upon completion
• Auto-restart function after power interruption—resumes prior settings without manual reconfiguration
• Compact footprint (260 × 195 × 150 mm) and lightweight construction (2.5 kg) for benchtop flexibility and space-constrained environments
• Modular interchangeability: supports 11 standardized block configurations (A–K), including formats for 0.2 mL PCR tubes, 96-well plates, 1.5/2.0 mL centrifuge tubes, 5–50 mL conical tubes, and custom-designed inserts

Sample Compatibility & Compliance

The JYH-100 accommodates a broad spectrum of common laboratory consumables through its configurable aluminum blocks. All modules are machined to ISO-toleranced depths and diameters to ensure secure fitment and optimal thermal coupling—critical for reproducible results in protocols governed by CLSI, ISO 15189, or internal SOPs. While the device itself does not carry CE, UKCA, or FDA 510(k) certification, its electrical safety design conforms to IEC 61010-1:2010 requirements for laboratory equipment. It is suitable for use in GLP-compliant environments when integrated into validated workflows; however, end-users are responsible for performing IQ/OQ/PQ verification per their institutional quality management system.

Software & Data Management

The JYH-100 operates as a standalone instrument with no embedded data logging or PC connectivity. All operational parameters—including set temperature, elapsed time, and remaining timer—are displayed locally via a 4-digit LED screen. For laboratories requiring audit trails or electronic record retention, external validation-grade data loggers (e.g., compliant with FDA 21 CFR Part 11) may be deployed alongside the unit to capture temperature profiles during critical processes. No proprietary software or drivers are required, eliminating compatibility constraints with modern Windows, macOS, or Linux platforms.

Applications

• Molecular biology: Pre-heating restriction enzymes, ligases, and master mixes prior to PCR setup
• Clinical labs: Warming serum controls, calibrators, and immunoassay reagents to specified incubation temperatures
• Pharmaceutical QC: Equilibrating solvents and standards before HPLC or dissolution testing
• Cell culture: Gentle warming of fetal bovine serum (FBS) or growth media without protein denaturation
• Environmental testing: Conditioning soil or water extracts prior to extraction or analysis steps
• Educational labs: Demonstrating thermal kinetics, enzyme thermolability, and basic incubation principles

FAQ

Is the JYH-100 suitable for temperature-sensitive enzymatic reactions?

Yes—its ≤ ±0.3°C stability at target setpoints and uniform block temperature distribution minimize thermal gradients that could compromise enzyme activity.
Can multiple modules be used interchangeably without recalibration?

Yes—each module is calibrated against the same reference standard during manufacturing; no user recalibration is needed when swapping blocks.
Does the unit support cooling functionality?

No—the JYH-100 is a heating-only dry block heater and does not incorporate active cooling elements.
What safety protections are built into the system?

It includes over-temperature cutoff, short-circuit protection, and thermal fuse redundancy to prevent uncontrolled heating under fault conditions.
How often should performance verification be performed?

Per ISO/IEC 17025 and CLIA guidelines, temperature accuracy and uniformity should be verified at least daily prior to use in regulated applications, using NIST-traceable thermometers or calibrated PT100 probes.
