LAB & SCHOOL

Even before masks became a common sight, we sold a bunch of N95 particulate respirators because Surpies have a long history of woodworking, model building and DIY renovating. Contractors love these! These masks are from 3M, (we don't get 3M masks often) model #8511 with a cool-flow valve, and are for filtration of particulates. Cool-flow valve keeps your face cool and, perhaps more importantly, dry. You’ll get (10) per box, and yeah, they’re made in the USA. Date Code is 2025

Now for the 3M Specs

• NIOSH approved for at least 95 percent filtration efficiency against certain non-oil based particles 
• Features the 3M™ Cool Flow™ Valve 
• M-Noseclip adjusts easily for fewer pressure points and greater comfort 
• Braided headbands two-strap design with dual point attachment helps provide a secure seal 
• Spacious and durable Designed to increase comfort and wearability 
• Advanced Electret Media is designed for ease of breathing

But maybe you don’t weigh enough? Make that, maybe you don’t weigh often enough. We’re talking about the precise weighing of substances topping out at 5000g, or 176 oz. Good for the lab or kitchen, this 7” x 5-1/2” digital scale has a stainless steel, brushed-aluminum top and a high-precision sensor. Stand stands about 1/4” high. Has a backlit LCD display, zero function, auto power-off, low battery indicator, overload indicator, g/ml/oz/lb’oz units, and it takes (2) “AAA” batteries, which you supply, along with whatever it is you’re weighing.

Stethos is Greek for chest. Indeed you can scope your stethos with this stethoscope, or your friend's or your dog's. But it works equally well for picking up any sound being transmitted through a solid medium. Listen to the air flowing through the heating ducts, the water in the pipes, the sounds of machinery, the termites munching on the floor joists!! The color does vary so we will select from what's currently available. We've had blue, teal, red, black, burgundy, green and purple, but there may be other colors yet to be seen! Not professional quality, but also not just a toy.

Good things come in (2) different small packages. Our pocket microscopes are compact and perfect for a clear, close look at stamps, coins, flora, insects or assorted minutiae. The 30X version measures 5-3/4" x 1-5/8" x 3/4" in black plastic with a focus knob, on/off switch, small LED for illumination, and a vinyl carrying case. Requires (2) "AA"s. The 60X version is a microscopic 3-1/4" x 1-3/16" x 3/4" and has a built-in white LED illuminator powered by (3) coin-cell batteries that are included. Magnifies from 60-100X, with coarse- and fine-focus knobs, and has a vinyl carrying case.

Inside the lab, it's a standard translucent-white, LDPE-plastic wash bottle, 500ml/16oz, measuring 2-3/4" dia x 6-3/4 tall with a screwcap and a right-angle, 5/16" dia nozzle. Outside the lab, it's so pleasing to squeeze and squirt with that some of us keep them in the kitchen.

This digital instant-read lab thermometer measures 8-1/4" long total with a 5" long stainless-steel probe that's resistant to most chemicals. Has a removable cover with a pocket clip, on/off button, and C or F readings (-50 to +300C, -58 to +572F). Button-cell battery included.  

If you lose sleep keeping track of your daily intake, have we got 2-in-1 special for you! This handy 500mL clear glass beaker mug not only proudly proclaims that it's for caffeinated beverages only, but it also has 50mL graduations to let you know just how much you've consumed. The front has the molecular symbol for caffeine, and is labeled as such for the non-chemists out there, while the back has the graduations, from 200-400mL. At 4-3/4" tall x 3-1/2" diameter with lip around the top it's a smidge taller than a normal mug and not intended for serious lab work as the volumes are approximate.

Porcelain mortars and pestles. Great heavy duty mortars, with sides that are easily 5/16" thick on the smaller ones, and up to 1/2" on the larger. The mortars are glazed outside, but rough inside, the better to grind, and have a pouring lip. The business ends of the pestles are unglazed, while the shafts are glazed. Very functional, very good looking!! So grind your own spices, fresh herbs or lab concoctions as you prefer. You get a mortar and pestle as a single order.

This small chrome constricting clamp is designed for controlling IV drips, but no doubt will inspire other uses for crafters, jewelry makers and those who want to control the flow from small pumps both air and fluids. Measure 2" x 1-1/4" OA when fully open. Flat clamp screws open to approx 5/8". The clamping surface is approx 3/4" x 1/4". Uber handy to have around. 

Stainless steel mortar and pestle set. Mortar measures 5-1/4” dia x 3” on a 4” dia attached saucer-like base. Holds approx 250ml. Pestle is 6-3/4” long with 1-1/4” and 2” dia heads. Nice for the lab, or for folks who want everything in their stainless steel kitchen to be stainless steel. You know who you are. And we salute you.

Yeah, you guessed it. They fit like a glove, like a pair of size Large vinyl, non-sterile, powder-free, disposable gloves from Cureguard Glove. You’ll get (100) of them, which works out to (50) pairs if you don’t have a calculator handy. You’re welcome—for the math and the hand protection.

This (10) piece set of weights are brass cylinders topped with knobs. The weights are stamped on the top. There are (2) each of 1, 2, 5 and 10 grams, plus (1) 20 and (1) 50 gram weight. Our each is the full set of 106g. 

If you want something done right…. and yes, that includes laboratory slides. This slide-making kit from Elenco makes a fantastic start to exploring the miniature world around you or great expansion to your microscope usage. Includes: a 4-chamber Micro Hatchery®, Vial of Shrimp Eggs, (2) Prepared Slides, (10) Glass Slides, (12) Cover Glasses, (12) Statical Slide Covers, (12) Labels, Vial of Eosins, Vial of Methylene Blue, Vial of Sodium Chloride, (2) Collecting Vials,  (2) 10mL Graduated Cylinders, Tweezers, Dropper, Stirring Rod, 3x/6x Magnifier, Safety Goggles and a great instruction Manual. Wow, that's not just a kit, it's a small lab!

Sometimes you just need a nice plastic tube with caps on the ends. You know it and we know it, which is why we’re carrying this one. Measures 5-3/4" long with a 0.79" (or 2cm) exterior dia and is made of transparent black/gray-tinted acrylic. Has black plastic plugs on both ends, and we’ll never ask you what you did with it. As long as you don’t ask us what we did with ours.

Eye dropper, tongue dropper, test tube dropper, petri dish dropper, anywhere dropper. Use this 3" glass dropper, with a rubber squeeze bulb to drop small amounts of liquid wherever you think they should go. You will have to measure by counting drops, though, because there are no markings on it. Also, it is called "3" because that is about how long the glass tube is. Overall, it is 4" long.

You know those times when you don’t have a stove and you wonder how you’re going to heat up your soup or mac and cheese? Like at college, or when you’re on the road and living in hotel rooms? Times like those are when this 110VAC, 1000-watt (9A) hot plate shines. Has an easy-to-use dial with (5) temperature settings, from 140F to 716F, a neon power indicator, metal body, non-slip feet and a 3-foot cord. Measures approx 8” x 8” x 2-3/4”. This is a serious cooking tool, not a toy, and shouldn’t be used by anyone under age 12. Anyone over 12 should operate the plate under the supervision of an adult. Just one, though. Too many cooks spoil the broth. CE listed.

When you peer through your magnifying glass at this specimen, or focus your microscope on it, even at the lower magnifications which work best, you're looking at one big bug. Make that (4) big bugs. The insects are real, encased in clear acrylic blocks 1-3/4" x 1-1/4" x up to 11/16" thick, and ready for inspection. Set 1 includes a scorpion, giant ant, wasp and a flower bug. Set 2 is a cricket, locust, yellow leaf beetle, and crab. No, not a crab louse or a crab spider, but definitely a crab ugly.

We’ll say. Herr Erlenmeyer of flask fame was handled Richard August Carl Emil Erlenmeyer, but you can call him Emil. Our Borosilicate glass version of his flask holds 500ml, and is graduated from 200ml to 400ml in 50ml increments. Stands 3-3/4” tall with a 4-1/4” dia bottom narrowing to 2-1/2” at the top, which also makes it a hard-to-spill coffee cup.
