Options & Accessories


Innovative hybrid design for maximum flexibility

Adding the monochromator option to your EnVision instrument enables you to select either the filter or monochromator mode on the same instrument. The EnVision system’s monochromators allow you to choose any wavelength and perform wavelength scans.

Ultra-Sensitive Luminescence technology makes the most of your precious cells and reagents

Working with primary, stem or difficult-to-transfect cells presents a unique set of challenges. Optional ultra-sensitive luminescence boosts sensitivity by almost 40X versus standard luminescence by bringing the detector closer to the sample—giving you more information from every cell.

Efficient, adaptable Alpha Technology

PerkinElmer’s highly versatile Alpha Technology is a homogeneous, bead-based platform that detects virtually any molecule from large endogenous protein complexes to very small peptides. Easy to automate and miniaturize, it works with a variety of sample types—all in one well and with no wash steps. There are two options available:

·        Standard AlphaScreen®involves excitation, delay and measurement of each sample sequentially

·        Laser-based HTS AlphaScreensimultaneously measures one sample while exciting another, removing the delay and providing a 2.5X speed boost.

TRF laser enhances signal-to-noise and accelerates measurement

A high energy laser for time-resolved fluorescence (TRF) gives superior signal-to-noise ratios and exceptionally fast measurement times—less than 36 seconds on a 1536-well plate, including plate loading times.



Temperature Control

To ensure reproducibility of cellular and enzyme kinetic assays and other assays that require a defined temperature range, the EnVision platform’s temperature control option lets you precisely regulate from +2°C to +45°C above ambient. Temperature control is uniform across the plate, and a top heating plate eliminates condensation problems.


The EnVision dispenser can be used with 1- to 384-well plates in all reading modes. It consists of two pump units, a magnetic stirrer and a heater, allowing precise delivery of reagents in 1μL increments over a volume range of 2-475μL. An adjustable dispense speed setting lets you optimize for viscosity, cell density and other assay requirements.

Plate Stacker

Available for 20 or 50 plates, interchangeable plate stacker magazines can easily be added to increase capacity and throughput. For kinetic assays, the grip-fed re-stacking function lets you maintain the order of plates in the stack, increasing the reliability of data.

Flexible Automation

For increased throughput or walkaway convenience, PerkinElmer offers a range of automation solutions that include full liquid handling systems such as the Janus® Automated Workstation. EnVision plate readers are also compatible with a wide range of third party automation systems.

Label-specific filters and optical modules

User-changeable, label-specific mirror modules and filters provide optimized detection sensitivity for every label and application. You can easily add modules to meet changing applications needs.


Cellular Assays

Bottom-reading, shaking, scanning, temperature control and kinetics capabilities make EnVision the reader of choice for cellular assays.

GPCR Assays

The EnVision system’s high throughput read technologies are a perfect match for a wide range of GPCR assay types such as AlphaScreen®, LANCE® and AequoScreen®.

Reporter Gene Assays

Scanning and kinetics capabilities and label-specific optical mirror modules and filters enable fluorescent protein assays and dual reporter gene assays using luciferase and beta lactamase.

Enzyme Assays

Accurate, stable temperature control and re-stacking capability let you perform sensitive kinetic measurements across a wide dynamic range and high-speed measurements at short-repeat intervals.

Kinase Assays

LANCE Ultra TR-FRET biochemical assays are ideal for tyrosine/serine/threonine kinases. Alpha technologies measure phosphorylated peptides, full protein substrates and endogenous phosphorylated proteins in cellular format.

Quantification Assays

A wide range of filters and optical mirror modules covering the UV/Vis spectrum enable direct measurement of DNA, protein and classical ELISAs. AlphaLISA, AlphaScreen and DELFIA® capabilities also allow use of ELISA alternatives that offer wider dynamic range and higher sensitivity.
