Vitl MicroTS Manual Microplate Sealer

Overview

The Vitl MicroTS Manual Microplate Sealer is a compact, fixed-temperature thermal sealing instrument engineered for precision sample integrity in life science laboratories. It operates on resistive heating principles, delivering consistent thermal energy to thermoplastic sealing films—such as aluminum foil, polyester film, or pressure-sensitive adhesives—applied over microplates used in PCR, qPCR, ELISA, and long-term biobanking workflows. Unlike programmable thermal cyclers or multi-zone sealer platforms, the MicroTS employs a single, factory-calibrated heating element maintained at 170 °C ±2 °C, ensuring reproducible seal formation without user-configurable ramp rates or dwell times. Its passive thermal architecture eliminates complex firmware dependencies, reducing calibration drift and supporting GLP-compliant documentation through manual logbook entries. Designed for benchtop integration—including laminar flow hoods and biosafety cabinets—the unit meets IEC 61010-1 safety requirements for laboratory electrical equipment and complies with RoHS and CE directives.

Key Features

• Fixed-seal temperature of 170 °C ±2 °C, optimized for rapid, uniform fusion of standard thermal sealing films without cold spots or over-sealing
• Compact footprint (220 × 250 × 230 mm) and lightweight construction (4 kg), enabling flexible placement in space-constrained environments including Class II biosafety cabinets
• LED status indicator provides real-time visual feedback: solid green indicates operational readiness; flashing red signals overheating condition, automatically disabling the heating element until thermal recovery
• Sub-10-minute preheat time enables immediate workflow integration—no extended warm-up delays between sealing cycles
• Modular adapter system supports standardized microplate formats: full-skirted (e.g., ANSI/SLAS 96-well), semi-skirted/unskirted, and deep-well plates (e.g., 96-well V-bottom or 384-well low-profile)
• No software dependency or USB connectivity required—operation is purely mechanical and tactile, minimizing cybersecurity exposure and IT validation overhead

Sample Compatibility & Compliance

The MicroTS is validated for use with commercially available heat-sealable films compliant with ISO 20776-1 (clinical microbiology) and ASTM D882 (tensile properties of thin plastic sheeting). It accommodates all ANSI/SLAS-standard microplates up to 96- and 384-well configurations when paired with the appropriate adapter (V903003, V903004, or V903005). Seal integrity has been verified per USP for extractables profiling under accelerated aging conditions (40 °C/75% RH for 30 days), confirming minimal leachables from sealed interfaces. The device itself carries CE marking under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to ISO 13485:2016 quality management requirements for medical device accessories used in diagnostic sample preparation.

Software & Data Management

The MicroTS operates independently of software control—no embedded firmware, no network interface, and no data logging capability. This design aligns with FDA 21 CFR Part 11 Annex A guidance for “non-electronic record” instruments, where operator actions are documented manually in lab notebooks or LIMS entries. For laboratories requiring audit trails, the device may be integrated into electronic batch records via external timestamped entries referencing seal date/time, plate ID, operator initials, and adapter type used. No password protection, user roles, or electronic signature functionality is provided—consistent with its classification as a Class I general-purpose laboratory accessory under MDR 2017/745 Annex VIII.

Applications

• PCR/qPCR plate sealing prior to thermal cycling to prevent evaporation-induced concentration shifts and cross-contamination
• Long-term archival storage of DNA/RNA extracts and clinical specimens under inert atmosphere or desiccated conditions
• Sealing of ELISA plates post-coating to minimize antigen degradation during incubation steps
• Preparation of sample arrays for automated liquid handlers—uniform seals ensure reliable pipetting accuracy and tip seal integrity
• Biobanking workflows requiring traceable, non-invasive closure of cryovial racks and microtube strips

FAQ

Is the sealing temperature adjustable?
No. The MicroTS operates exclusively at a fixed temperature of 170 °C ±2 °C, calibrated at the factory and not user-modifiable.
Which microplate formats are supported?
All ANSI/SLAS-compliant 96-well and 384-well plates—including full-skirted, semi-skirted, unskirted, and deep-well variants—when used with the corresponding Vitl adapter (V903003, V903004, or V903005).
Does the MicroTS require routine calibration?
Annual verification of temperature accuracy using a NIST-traceable surface probe is recommended per ISO/IEC 17025 guidelines, though no internal recalibration procedure is available.
Can it be used inside a biosafety cabinet?
Yes. Its low power draw (<150 W), absence of forced-air cooling, and compact dimensions allow safe operation within Class II A2 and B2 cabinets without airflow disruption.
Are sealing films included with the instrument?
No. Compatible heat-seal films must be sourced separately and selected based on downstream assay compatibility—e.g., UV-transparent films for absorbance assays or low-extractable foils for mass spectrometry applications.
