What is New Star Environmental?
New Star Environmental is a supplier of environmental monitoring and laboratory instrumentation and supplies. Its catalog centers on air sampling, aerosol particle measurement, particle counters, labware, and related field and lab equipment, alongside accessories such as filter storage dishes and vacuum pumps. The site also presents the company as service-oriented, emphasizing experience and customer support rather than acting as a pure marketplace.
Who it suits
- Air quality and emissions researchers who need sampling and filter-handling supplies for field and lab work.
- Industrial hygienists and environmental technicians verifying or calibrating personal and environmental sampling pumps.
- Laboratories buying general labware and oil-free air or vacuum equipment.
Practical trade-offs
The range spans consumables and instruments, which can simplify purchasing from one vendor, but it is not a deep specialist catalog in every category. Product pages emphasize short feature lists rather than extensive comparison data, so for instrument selection you will usually need to check the manufacturer's documentation for detection limits, flow ranges, and certifications.
As a next step, decide whether you are buying a consumable (for example, filter storage dishes for transporting ambient or emission samples) or an instrument (such as a flow calibrator for routine pump checks). For the latter, confirm the required flow range and calibration standard before ordering.
What types of environmental monitoring instruments does New Star Environmental sell?
New Star Environmental sells environmental monitoring and laboratory instruments, with a stated focus on aerosol particle measurement. Its catalog spans particle counters, air sampling equipment, gas leak detection, flow calibration and general labware.
Main instrument categories on the site
- Gas leak detection: The Gascheck G handheld leak detector is presented for rapid, accurate gas leak measurement, aimed at field technicians checking lines, fittings or equipment for leaks.
- Air sampling: The site offers air sampling products and filter storage and shipping containers such as PetriSlides dishes, described for ambient and emission air quality fieldwork and lab analysis.
- Flow calibration: The mini-BUCK M-5 primary flow calibrator is positioned for day-to-day verification and calibration of personal and environmental sampling pumps.
- Sampling pumps and air supply: The Rocker 300 vacuum pump (oil-free piston design, marketed as maintenance-free) and the Rocker 440 oil-free air supply system serve sampling and clean-air supply roles.
- Particle measurement: Aerosol particle measurement is named as the company's central application area, so particle counters are the category to look for first if that is your task.
- Laboratory products: General labware is sold alongside the instruments, which suits buyers equipping a lab and a field kit from one supplier.
Who this fits
A typical buyer is an air quality consultant or university lab that needs a sampling pump, a flow calibrator and filter carriers together, then wants a single source for consumables. A technician doing leak surveys on industrial equipment would look at the Gascheck G instead.
How to choose
Decide first whether your work is particle counting, gas detection or pump-based sampling, then confirm the voltage and plug variant (the Rocker listings show AC100-120V and AC220V/EU plug options) and whether calibration support is available for flow devices. As a practical next step, compare the mini-BUCK calibrator against your existing pump models, since calibration compatibility matters more than brand.
For broader comparison, official sites such as TSI and Sensidyne cover particle counters and gas detection respectively.
How do I choose between a handheld gas leak detector and an air sampling pump for my field work?
The choice depends on what you need to detect. A handheld gas leak detector like the Gascheck G, featured on New Star Environmental, is for finding where a specific gas is escaping; an air sampling pump draws air through a filter or sorbent so you can measure what is in the air over time. They answer different questions, and many field programs use both.
When a handheld leak detector fits
- You suspect a leak from equipment, cylinders, fittings or pipework and need to locate it quickly.
- You want an immediate reading in the field rather than a sample sent to a lab.
- The gas in question is one the instrument is designed for; check the target-gas and sensitivity information before relying on it.
When an air sampling pump fits
- You need a time-integrated sample (for example, personal exposure or ambient air quality) collected on a filter or sorbent tube.
- You need flow control and calibration, which is why a calibrator such as the mini-BUCK M-5 appears alongside pumps in the same catalog.
- You are sampling for particulates or multiple compounds rather than tracing a single leak.
A practical comparison
| Criterion | Handheld leak detector | Air sampling pump |
|---|---|---|
| Main purpose | Locate and confirm a leak | Collect air for later analysis |
| Typical output | Immediate reading on site | Sample for lab or gravimetric analysis |
| Key setup need | Correct target gas and response check | Calibrated flow rate and suitable media |
| Best for | Maintenance, safety walk-throughs, troubleshooting | Exposure monitoring, compliance sampling, research |
A concrete scenario
A technician checking a cylinder manifold would start with a leak detector to pinpoint a suspected leak. A hygienist assessing a worker's daily exposure would use a calibrated pump and sampling media. If both tasks fall in one visit, carry both; the detector screens, and the pump documents.
How to decide
- Define the question: locate a source, or quantify exposure over time?
- Confirm the instrument supports your target gas or sampling medium.
- Check that you can calibrate and maintain it in the field.
- Call the supplier with your gas list and sampling goals; New Star Environmental lists a phone number and invites contact, which is a sensible next step before buying.
What accessories and labware do I need to store and transport air sampling filters?
For storing and transporting air sampling filters, the core items are a sealed filter storage and shipping container (often a Petri-style dish or slide holder) and, for gravimetric work, a clean, protected carrier that keeps filters flat and free of contamination. New Star Environmental lists a filter storage and shipping dish described as suited to ambient and emission air quality field and laboratory research and analysis, which is the type of container this task calls for New Star Environmental.
What the kit usually includes
- Primary container: a Petri-style dish or slide holder that holds filters flat, closes securely and is labeled for sample ID.
- Secondary carrier: a rigid box or case that protects dishes during transport and keeps them upright.
- Handling tools: clean forceps and gloves so filters are never touched directly.
- Conditioning and weighing support: a desiccator or clean balance area if filters are weighed before and after sampling.
- Field labels and log sheets: to record site, time, flow rate and filter ID.
Choosing between options
| Need | Better fit | Trade-off |
|---|---|---|
| Short field trips, few filters | Simple sealed Petri-style dish | Less protection if the case is dropped |
| Multi-day or multi-site campaigns | Rigid carrier holding several dishes | Bulkier and heavier to carry |
| Gravimetric analysis | Desiccator plus sealed dish | More steps and conditioning time |
A practical next step is to count filters per sampling day and match container capacity to that number, then confirm the dish seals tightly enough for transport. For filters that will be weighed, keep a dedicated desiccator and handle filters only with forceps.
Which products help me calibrate air sampling flow rates in the field?
The most directly relevant product on New Star Environmental is the mini-BUCK Calibrator M-5, which the site describes as a primary flow calibrator for day-to-day verification and calibration of personal and environmental sampling pumps. That is the item to start with if your field task is confirming that a sampler is drawing the flow rate you set.
How to choose within the catalog
- Calibrator first: The mini-BUCK M-5 is positioned for routine field checks of sampling flow. If you already own sampling pumps, this is the piece that turns "the pump says 2 L/min" into a verified number.
- Pump support: The Rocker 300 Vacuum Pump (23 lpm, AC100–120V) is a lubricant-free piston pump the site lists for sampling and vacuum work. It is a pump, not a calibrator, but it is the kind of device a calibration routine would be checking.
- Sample handling around the calibration: The PetriSlides filter storage and shipping dish is for ambient and emission air quality field and lab work. Useful for keeping filters clean during a field campaign, but it does not measure or set flow.
- Gas leak checks are a different job: The Gascheck G Handheld Leak Detector is for locating gas leaks, not for verifying volumetric flow through a sampling train.
Practical field scenario
Suppose you are running personal sampling pumps on a multi-site air quality study. Each morning you attach the mini-BUCK M-5 in line with a pump, compare the indicated flow against the calibrator's reading, and adjust the pump before sampling begins. At the end of the day you recheck, because pump flow drifts as filters load. The PetriSlides container keeps the collected filters intact in transit; the Rocker pump serves separate vacuum needs in the same campaign.
Decision criteria
- Your goal is flow verification: choose the calibrator.
- Your goal is moving air or creating vacuum: choose a pump.
- Your goal is detecting a leaking gas line: choose the leak detector.
- Your goal is preserving samples: choose the storage dish.
For a broader comparison of primary and secondary flow calibrators before buying, the U.S. EPA's air monitoring guidance at U.S. EPA and the occupational sampling methods published by CDC/NIOSH explain which calibration approach each method expects.
Does New Star Environmental offer oil-free vacuum pumps suitable for laboratory air sampling?
Yes. New Star Environmental's catalog includes oil-free vacuum pumps aimed at laboratory air sampling. The Rocker 300 Vacuum Pump is listed at 23 lpm with AC100–120V, 50/60Hz power, and the page describes the Rocker series as piston-driven with no lubricant required, which means no oil mist or oil-change maintenance. A second option, the Rocker 440 Oil-Free Air Supply System, is listed with AC220V, 50Hz and an EU plug, so it suits a European power setup rather than a North American one.
For a lab running personal or ambient air sampling, the practical fit is a pump that matches your sampler's required flow and your facility's voltage. The Rocker 300's 23 lpm capacity suits low-to-moderate flow sampling setups; if your method needs higher or calibrated flow, pair the pump with a flow calibrator such as the mini-BUCK M-5 listed on the same site, which is described for day-to-day flow verification of personal and environmental samplers. Check the sampler's flow requirement and plug type before ordering, since the two pumps differ in both.
If you want to compare oil-free pump lines from other suppliers, SKC and Zefon International are established air-sampling equipment sources worth checking for flow ranges and voltage options.
