TAITEC XY-80 Precision Oscillating Water Bath

Overview

The TAITEC XY-80 Precision Oscillating Water Bath is an engineered platform for controlled thermal incubation combined with programmable mechanical agitation. Designed for reproducible biochemical and microbiological workflows, it integrates PID-controlled heating with three distinct oscillation kinematics—reciprocating, orbital, and figure-eight—each optimized for specific vessel geometries and mixing requirements. Unlike static water baths or single-mode shakers, the XY-80 enables dynamic fluid motion within temperature-stabilized environments, supporting applications ranging from bacterial culture expansion and enzyme kinetics to serum inactivation and media pre-warming. Its construction adheres to JIS Z 8103 and ISO/IEC 17025-aligned manufacturing practices, with thermal performance validated under ambient conditions per ASTM E2251–22 (Standard Practice for Calibration of Liquid-in-Glass Thermometers).

Key Features

• Triple-Mode Oscillation Kinematics: Select between reciprocating (linear back-and-forth), orbital (circular path), and figure-eight motion—each mechanically actuated via a precision cam-driven linkage system. The figure-eight mode ensures uniform shear distribution across rectangular containers (e.g., plastic storage boxes) and conical flasks, minimizing vortexing artifacts while maximizing oxygen transfer efficiency.
• High-Fidelity Thermal Regulation: Equipped with a Pt100 RTD sensor and digital PID controller, the bath maintains setpoint stability within ±0.02–0.1 °C across its full operating range (RT + 5 °C to 80 °C). Internal recirculation ensures homogenous temperature distribution (±0.15 °C spatial uniformity, measured at 5 points per IEC 61000-4-30).
• Intuitive Operator Interface: LED-based dual-display shows both setpoint and real-time bath temperature (0.1 °C resolution). Dedicated illumination indicators confirm active oscillation mode. Parameter entry uses tactile UP/DOWN keys; no touchscreen dependencies reduce maintenance complexity in humid lab environments.
• Modular Platform System: Includes a standard spring-grid platform (20 mm pitch) compatible with common labware: up to 204 × 16 mm test tubes, 24 × 50 mL Erlenmeyer flasks, or 6 × 500 mL shaking flasks. Optional clamping fixtures provide secure retention for tall or top-heavy vessels during high-speed operation (≥120 rpm).
• Robust Safety Architecture: Integrated safeguards include overtemperature cut-off (independent bimetallic switch), dry-run protection (level-sensing circuitry), real-time sensor fault diagnostics, and visual alarm indication for thermal deviation (>0.5 °C from setpoint for >30 s).

Sample Compatibility & Compliance

The XY-80 accommodates glass, polypropylene, and borosilicate vessels up to 2 L capacity. When operated above 70 °C, silicone oil (not included) must replace water as the heat-transfer medium—consistent with ISO 15190:2020 recommendations for high-temperature bath safety. The unit complies with IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and carries PSE certification for use in Japan. While not intrinsically rated for Class I Division 1 environments, its sealed heater assembly and drip-proof enclosure meet IP22 ingress protection standards.

Software & Data Management

The XY-80 operates as a standalone instrument without proprietary software dependency. All parameters are configured locally via front-panel controls. For integration into GLP/GMP-regulated workflows, optional RS-232 or analog 4–20 mA output modules (sold separately) enable connection to centralized data loggers compliant with FDA 21 CFR Part 11 requirements. Audit trails—including temperature setpoint changes, mode selection events, and fault logs—are timestamped and stored onboard for ≥30 days (non-volatile memory). Remote temperature setting is supported via external voltage input (0–5 V DC), facilitating integration with building management systems.

Applications

• Microbial cultivation of Escherichia coli, Bacillus subtilis, and other aerobic strains requiring consistent O₂ transfer and thermal uniformity.
• Enzymatic assays where reaction rate depends on both temperature and mixing homogeneity—e.g., restriction digests, ligations, and phosphatase treatments.
• Serum heat inactivation (56 °C, 30 min) with minimal protein denaturation due to low-shear figure-eight agitation.
• Pre-warming of culture media, agar solutions, or reagent stocks prior to aseptic handling.
• Accelerated solubility testing of polymers or APIs in aqueous or silicone-oil matrices under controlled thermal stress.

FAQ

Can the XY-80 operate with oil as the bath medium?
Yes—silicone oil is required for sustained operation above 70 °C. Verify oil viscosity and flash point compatibility per manufacturer specifications before use.
Is the oscillation speed adjustable in real time during operation?
Yes—speed is continuously tunable from 20 to 160 rpm using front-panel controls, with closed-loop feedback maintaining setpoint accuracy within ±1 rpm.
Does the unit support external temperature probes for sample monitoring?
No—the built-in Pt100 sensor monitors bath temperature only. Sample-specific temperature measurement requires insertion of a calibrated external probe into the vessel.
What is the maximum load capacity of the spring-grid platform?
The platform supports up to 8 kg distributed load; exceeding this may compromise oscillation uniformity and long-term mechanical integrity.
Is calibration documentation provided with shipment?
Each unit ships with a factory calibration certificate traceable to JCSS (Japan Calibration Service System), including as-found and as-left temperature deviation data at 37 °C and 60 °C.
